Dont Just Use Your Data‚ Exploit It!Adam James, Jeff Cherwonik, Brandon BryantThe Data Age is here. Data are being collected at an exponential rate and cost analysts are struggling to exploit it. Limited structured contextual information and clunky formatting are significant barriers to efficient use. This paper demonstrates the importance of establishing a modern data strategy that considers how analysts identify, access and use data in the context of an example exploitation of a large CSDR data set for the Armys Stryker Family of Vehicles.2019Analysis & Modeling
Production System Cost Modeling Within an MBSE EnvironmentDan Kennedy, Karen MourikasModel-based Systems Engineering (MBSE) incorporates digital models to represent system-level physical attributes and operational behavior throughout the system life-cycle to support product development. To date, many MBSE efforts have focused on technical requirements with little emphasis on cost. Integrating cost models into MBSE provides visibility into cost impacts of design decisions. This presentation explores optimizing production-system design, manufacturing processes, and operations, by integrating various internal and industry production-system cost models into an MBSE environment.2019Analysis & Modeling
An Upgrade to Anderlohrs Retrograde Method for Broken LearningTommie MillerBreaks in production cause havoc for managing and estimating program costs. Estimators must consider the loss of efficiencies that will result from the break as well as the expected rate of learning after the break. Anderlohrs Retrograde Method is a popular technique for estimating the cost of broken learning, but it suffers from a weakness that arise when the learning slope changes at the break. This paper describes this weakness and suggests a robust solution.2019Analysis & Modeling
The Beginning of the End of Traditional Analogous ‚¬ËœBottoms-up EstimatingChris PriceTraditional bottom-up estimating methodologies are under fire due to inconsistency and inaccuracy. Leveraging advanced data-driven techniques is key for accurate, rapid cost estimating. Based on a recent endorsement provided by the DCAA in their 2018 Audit Manual, acceptance of alternative estimating methodologies other than ‚¬Ëœbottoms-up are now acceptable. We will present a disruptive process for transitioning from a traditional costly, time-consuming analogous ‚¬Ëœbottoms-up Basis of Estimate (BOE) bidding process to a new, more cost-effective process2019Analysis & Modeling
Adaptive Curve Fitting: An Algorithm in a Sea of ModelsMichael SchiavoniAdaptive Curve Fitting (ACF) is a novel technique that analyzes finite time series data such as monthly expenditures for government acquisition contracts. By intelligently fitting known resource phasing curve forms to an existing sequence of data, it generates a custom model that extrapolates the remaining values. This enables a variety of joint cost, schedule, and phasing analyses. ACF is based in theory and empirical research, shares similarities with existing techniques, and introduces several key innovations.2019Analysis & Modeling
Hybrid Cost Estimating: The Union of Macro and Micro-ParametricsDale ShermonAt the pre-concept phase of a project the nature of the solution is varied and the number of options numerous. As the project moves into the later phases the feasibility studies begin to produce more information and the number of options starts to reduce. In a hybrid cost estimating framework solution it is possible to migrate from a macro to a micro parametric cost model without need for training or skills.2019Analysis & Modeling
Schedule Estimating Relationship Development Using Missile & Radar DatasetsSara Jardine, Justin Moul, Donald TrappThis paper addresses the challenges of collecting useful historical schedule data for missiles and radars. The objective was to develop schedule estimating relationships and descriptive statistics for predicting the time between major acquisition milestones based on technical parameters. Major milestones are not always clearly defined and consistent. The difficulties of collecting and analyzing schedule data are highlighted. Various schedule drivers are discussed. The results provide a cross-check on the reasonableness of projected schedules for new programs.2019Analysis & Modeling
Estimating Chinas Defense Expenditures (AM08)Jack BianchiWhile DoD releases detailed budget data, China releases virtually none. The Center for Strategic and Budgetary Assessments developed a straightforward, adaptable, and strategy-driven program, the Strategic Choices Tool (SCT), which allows users to modify planned U.S. military force structure and modernization spending over the next decade. We are developing an SCT for Chinese defense spending. This presentation addresses cost estimation methodologies for Chinas procurement, personnel, and O&M costs, and preliminary data collection and modeling efforts.2019Analysis & Modeling
Measuring Portfolio Value for Government Programs and InitiativesGeorge Bayer Jr., Bryan AndersonTransformational government initiatives which require major capital investments or acquisitions are complex, difficult to measure, and challenging to articulate to decision-makers. Considering the complex dependencies and implementation risk of individual programs, risk-adjusted cost estimates for portfolios are often overstated. This paper examines how cost estimators and analysts measure portfolio value and generate stakeholder advocacy for major government initiatives, which require multiple acquisitions for implementation and agency policy changes to change behaviors and realize value.2019Processes & Best Practices
2020 Census Cost Estimation - GAO Audit Lessons LearnedEdward Kobilarcik, Neala JonesThe 2020 Census LCCE is a large, complex estimate with a projected $15 billion total cost. In 2016, the GAO assessed the estimate as only partially meeting any of the GAOs four characteristics of a quality cost estimate. Using the GAOs Cost Estimating and Assessment Guide, the 2020 Census LCCE team used a data-driven analysis to improve the LCCE and its supporting documentation. The result was a drastic improvement in the 2017 GAO assessment.2019Processes & Best Practices
GAO Updated, New, and Coming Best Practice GuidesJennifer Leotta, Brian BothwellThis session will go through GAO's updated, new, and forthcoming best practice guides. This includes a review of the best practices described in the cost guide, schedule guide, technology readiness assessment guide, and Agile assessment guide.2019Processes & Best Practices
Contractually Speaking: The Story of DOD Contracts & Potential ConsequencesOrly Olbum, Stephanie Lee, Peter BraxtonA contract is the legal document holding government and contractor accountable for their responsibilities and can play a significant role in cost and schedule issues throughout its lifetime. This paper utilizes the Contracts Database and CADE to investigate whether or not contract vehicles themselves contribute to these issues. We also dive into the acquisition process to determine the efficiency of different contract vehicles and how profit may impact a contracts success or failure.2019Processes & Best Practices
Business Case on the Cost/Benefit of U.S. Government Support of Contractors in order to Maintain CompetitionTodd Pardoe, John Stedge, Chad Bielawski, Jaimie SmithThe DoD is facing shrinking industrial bases in its acquisitions due to contractor mergers, specific military applications, and scarcity of materials. National security, strategic posturing, and Congressional interest make it vital to keep these industries viable and competitive. Mitigating the risk of ‚“shrinking industrial bases‚ offers unique opportunities in structuring these acquisitions. This study looks at the costs and benefits associated with strategies for acquisition of defense systems within the constraints of shrinking industrial bases2019Processes & Best Practices
Engineering the Acquisition Process: Better Value Through Mechanism DesignChristian Smart, Britt StaleyAs both the regulator and the only buyer in a market that measures over $500 billion a year in acquisitions, the Defense Department has tremendous leverage but does not make full use of it. Limited competition in the prime contractor market results in higher prices and lower quantities purchased. There have been some recent strides made to achieve better value, but much more can be done if the government will pursue strategic approaches. In this paper, we consider the use of mechanism design to achieve better value.2019Processes & Best Practices
Comparing Cloud Costs Equitably: J-Funded Capability DevelopmentKevin Buck, John Dubelko, Matthew Griesbach, Anthony RojasGovernment agencies often base cloud investment decisions on prices quoted in published cloud calculators and rate cards that invariably apply different service offering assumptions and cost drivers. The likelihood of making decisions based on incomplete or misunderstood data is high, and misinformed investment decisions can unfortunately be quite costly. MITRE evaluated several predominant commercial and government vendor solutions and developed a suite of vignettes that highlight challenges in comparing price quotes on an apples-to-apples basis.2019Computing
The 11th Commandment: Thou Shalt Migrate to the CloudEmily Hagerty, Orly Olbum, Brian FlynnAnd God gave unto Moses on Mt. Sanai and to General Mattis in the Pentagon the 11th Commandant: Migrate to the Cloud. This paper presents research that supports mission owners, program offices, and cost components in their quest for the Holy Grail ‚¬ cost effective and cyber-security compliant migration of legacy systems and data to the cloud. It offers innovative artifacts to support up-front requirements and trade-space analyses and back-end cloud design, build, testing and deployment.2019Computing
Predictive Analytic Estimates of Cloud Costs for Government IT SystemsRichard Mabe, Dan HarperThe White Houses ‚“Cloud Smart‚ strategy encourages agencies to consider life cycle costs focused on three main ‚“pillars‚: workforce, procurement, security. IT funding requires two years to approve and allocate a budget; so commercial Cloud rates will not be known as the budget is approved. Cost estimates must therefore capture historical workforce, procurement and security cost trends to estimate future solutions. Predictive analytic estimating approaches can provide effective estimates using calibrated historical data.2019Computing
Measurements in CyberspaceArlene MinkiewiczAddressing cybersecurity and software assurance is becoming increasingly important within the DoD and beyond. With software systems constantly talking amongst themselves and across various networks, concern is growing about the protection of our sensitive data and applications. But one must also consider how much security is too much and when the ‚¬Ëœright degree of cybersecurity has been achieved. This paper discusses cybersecurity and presents measurements suitable for accessing the efficacy of mitigation strategies.2019Computing
Cost Analysis Needed for Blockchain EffortsHarvey ReedU.S. government offices are exploring blockchain to address key challenges in their missions. The motivation stems from blockchain enabling peer-to-peer information sharing, without a centralized authority, which in turn supports execution of processes which span organizations. Currently, government lacks tools to describe blockchain projects with sufficient consistency to support acquisition and cost analysis. This presentation proposes a blockchain descriptive framework as a first step, with a focus on cost elements and drivers for blockchain projects.2019Computing
Forecasting Future Amazon Web Services PricingHassan Souiri, Andrew KicinskiThe National Reconnaissance Office (NRO) Cost and Acquisition Assessment Group (CAAG) produces independent cost estimates to support decision making, budgeting and trade studies. Cloud service costs procured from Amazon Web Services (AWS) are becoming increasingly scrutinized. A thorough analysis was conducted to collect historical AWS prices and model the downward trend. Autoregressive time series models were fit to storage and compute service prices, resulting in annual price reduction rates to be applied to future estimates.2019Computing

Simplifying the Estimate without Sacrificing QualityJeremy GoucherA typical Plan of Actions and Milestones for an ACAT 1 cost estimate is six months. This includes time to define the scope, define the WBS, research and analyze data, develop the estimate, iterate, brief, iterate again, brief again, and so on. Simplifying the estimate will result in shorter research and analysis periods, easier model revisions, easier quality assurance, and easier to understand presentations. This presentation will discuss various methods and processes for simplifying the estimate without sacrificing quality.2019Communication & Visualization
Data Visualization ‚¬ a Product of Human DesignBenjamin KwokCost estimates are based on data analysis and statistical methodologies that capture complex behavior in mathematical terms. One of the biggest challenges estimators face is describing their analyses in a way that a decision maker can quickly grasp and apply. Data visualization is an important skill set that analysts can use to present complex results in a clear and compelling manner. This presentation will provide an overview and show the benefits of data visualization.2019Communication & Visualization
The Point Estimate Is Not the PointJack Snyder, Joe BauerThe purpose of cost estimating and analysis is to inform planning decisions and secure sufficient / timely funding to facilitate program execution. Or is it? The authors will explore how tangible and intangible roles of cost estimators can better inform design, acquisition strategy, and planning decisions early. Traceable, repeatable, credible and flexible analytical models help to paint the quantitative picture, enabling decision makers to accurately plan a successful program.2019Communication & Visualization
Clearly Communicating Your IGCE to Decision MakersChristopher SvehlakAll that work gathering data, crunching numbers and running sensitivity tests for Independent Government Cost Estimates. Not done yet‚¬now comes communicating them. Its more art than science. Leaders need the key details and facts. But they can get hazy amidst probability distributions, parametrics, discounting, inflation and other elements. This presentation uses a real (sanitized) cost estimate, providing tried-and-true examples of getting the message across‚€understandably, concisely, and decision-ready.2019Communication & Visualization

Machine Learning Assisted Data Extraction and NormalizationJonathan Brown, Devin GeraghtyData collection and normalization is a key component of analysis. However, it often requires significant time and effort to properly extract quality normalized data from the raw datasets. Given the recent proliferation of larger datasets a more automated approach to data extraction and normalization is required. This research applies machine learning text classification algorithms and methods to automate historically manual data normalization tasks.2019Machine Learning
The Robot Forecaster--A Continued Study of Artificial Neural Network ApplicationNathan EskueIf your job includes predicting the future then you understand the difficulties of the "unknown", of all the little gremlins (sometimes called risks) that can mess up the most elegant and well thought-out plan. There are data models and statistical methods that can help a great deal, but if the conditions are right, a relatively new tool that is as accessible as it is misunderstood might just be what you need. We will cover the basics of Artificial Neural Networks and I'll share the progress I've made since ICEAA 2018 in putting these digital brains to work.2019Machine Learning
Don't be Scared, Machine Learning is EasyMary Johnson, Dakota ShaferThus far the field of cost estimating has only explored the pedagogical utilization of machine learning within cost estimating. The novelty of machine learning makes it difficult to find real use cases demonstrating the efficient application of machine learning to the cost estimating process. This paper and accompanying presentation will document a case study exploring the data cleaning and modeling process for a cost estimate done on DoD installations.2019Machine Learning
Machine Learning and Natural Language Processing Applications for Cost AnalysisKaren Mourikas, Jose Lemus, Enrique SerrotHow can machine learning and natural language processing enhance the traditional methods of cost analysis? By analyzing larger datasets more easily than the human brain can, and by automating many of the manual, time-consuming tasks needed to cleanse and prepare the data for analysis. This presentation examines several applications in which we integrated Natural Language Processing using python libraries, with various Machine Learning methods, in particular trees, randomization, and boosting, to improve prediction accuracy.2019Machine Learning
Beyond Regression: Applying Machine Learning to ParametricsKimberly Roye, Christian SmartCost estimating has relied primarily upon regression analysis for parametric estimating. However, regression analysis is only one of many tools in data science and machine learning, and is a small subset of supervised machine learning methods. In this paper, we look at a variety of methods for predictive analysis for cost estimating, including other supervised methods such as neural networks, deep learning, and regression trees, as well as unsupervised methods and reinforcement learning.2019Machine Learning
Data Impacts on System Readiness and CostPaul BrownOperations and support costs are becoming increasingly in focus as system readiness is addressed. This paper will discuss the impact data has on forecasting readiness and the corresponding effects on cost. Identifying ‚“correct‚ data and sources, such as CSDRs and OEM data reporting systems, plays an important role in modeling both cost and readiness. Different approaches to improve readiness and their impacts on cost and data needs will be discussed.2019Methods
A New Approach When Cost/Capability Trades Matter MostJeffery Cherwonik, Adam James, Richard BazzyConsideration of life cycle costs (LCC) early in the acquisition process, specifically prior to Milestone A, is paramount to credible requirements generation and improves the probability of program success. This paper describes a parametric universal wheeled ground vehicle LCC model based on CSDR data and designed for integration into a modeling and simulation environment that produces alternative vehicle designs. The LCC model uses outputs from a requirements-driven preliminary design model to generate informed cost vs. capability/requirements trades. 2019Methods
Five Steps for Improving the Accuracy of Rough Order of Magnitude Estimates ‚¬ Bell V-280 Wing Predictive Cost Analytics Case StudyZachary Jasnoff, Ross RaburnAccording to the GAO Cost Estimating and Assessment Guide, ROMS are ‚“developed when a quick estimate is needed, and few details are available‚. This leads to challenges with ROMs especially when estimates become ‚“locked in‚ early, based on the least accurate data. We will discuss five enabling steps that estimators can take to improve the accuracy of ROM estimating. This includes using a predictive analytic data driven methodology for leveraging and extrapolating limited data sets.2019Methods
Intellectual Property Valuation: An OverviewCynthia PrinceIntellectual property (IP) refers to inventions, literary and artistic works, designs, and symbols, names and images used in commerce. IP is protected by patents, copyright and trademarks, which enable earning of financial benefit from these inventions or creations. While most cost estimators already know that, what do we know about IP valuation? If asked to derive a cost estimate for IP valuation, what approaches could be taken? This overview will answer that question and more.2019Methods
PAC Template - Program Acquisition Cost (PAC) TemplateHorace White, Jim Cain, Raymond GarridoOne of the goals of our young and upcoming cost organization was to create a universal cost model template. Fast forward 6 years and the template we developed introduced standardization, a starting point for new analysts, minimized tedious work, and reduced common errors. We would like to share the success story of the cost model template and the lessons learned through the 6-year development process.2019Methods
Self-Organizing Markets And TimeDoug HowarthMarkets demonstrate statistically significant self-organization concerning how they respond to changes in prices and the product features offered to them. The nature of these self-organizing activities changes over time. What works for a market now may not work a few years from now. Being able to characterize market self-organization now and in the future is key to optimizing financial success, which this paper examines.2019Planning & Strategy
Contracting for Agile ProjectsBlaze SmallwoodThe nature of agile, with its flexible approach to requirements and stress on incorporating feedback from frequent stakeholder engagements, makes contracting for agile projects particularly difficult. This paper proposes a new idea that uses a capability-based incentive structure, which is currently being considered on upcoming Department of Defense contracts. The paper will present the mechanics of implementing this approach, its pros and cons, and a comparison to other approaches recently used on similar projects.2019Planning & Strategy
Enhance Estimator Success & Organization Competitiveness in Supplier AssessmentJohn SwarenThis presentation reviews the use of an effective methodology to perform Supplier Assessment. Estimator success and organizational competitiveness are enhanced when supplier quotations can be assessed and validated, leading to stronger negotiation positions as well as basis for preferred suppliers. This paper offers a quantitative methodology to benchmark, monitor and evaluate potential suppliers of a customer-specified technology. Once established, a Supplier Assessment capability creates the outcome of timely consistent bid evaluations as well as ceiling prices for negotiation.2019Planning & Strategy
Application of Conjoint Regression to Requirement AnalysisJacob WalzerConjoint analysis provides a simple method of measuring how the tradeoff between different capabilities can affect the perceived value of a product. Normally associated with marketing research, it can also be utilized to help estimate the cost of developmental items based on their expected requirements. This presentation explores the best practices, common pitfalls, and validation techniques associated with conjoint regression, and includes a notional example derived from an application of this technique in a USMC tradeoff analysis study.2019Planning & Strategy
Creating a Cost Driver S-CurveSandy BurneyS-Curve analysis is not just for Risk Analysis. It can be used for both Contractor and Government Cost Driver analysis. The presentation will: 1) describe the similarities and differences between Cost Driver and Risk Analysis; 2) provide a rational for doing an S-curve on Cost Drivers early in the procurement lifecycle; 3) provide detailed steps to developing a Cost Driver S-Curve; and 4) display examples of Cost Driver S-Curves and additional outputs that result from the analysis.2019Risk
The 3-Point Method Redux: Estimating Cost Uncertainty Given Only a Baseline CostMarc GreenbergLeveraging a 2007 paper entitled ‚“Estimating Cost Uncertainty when only Baseline Cost is Available,‚ this presentation revisits the 3-point method: a scenario-based application of the Analytical Hierarchy Process (AHP). This presentation steps through an overview and notional example on applying the 3-point method to demonstrate how pessimistic and optimistic costs are derived from a given baseline cost. These three costs, in turn, serve as the requisite three parameters of the triangular distribution.2019Risk
When is Less More? Level of Detail in Cost and Schedule Risk AssessmentLaura Krepel, Zachary PirtleWhen performing cost and schedule risk assessment (C)SRA, the level of detail in the analysis schedule dictates the time to build, validate, and review the model. In this brief, we will discuss the pros and cons of using a more or less detailed analysis schedule as the basis for these models, whether 10s or 10,000s of lines. We will explore the level of effort, accuracy, and value (stakeholder understanding) of each approach through the use of real-life scenarios, based upon the authors' experience developing models for NASA and other federal agencies. An overview of the basic requirements for any SRA or JCSA, including detailed schedule for execution, monitoring, and control of the schedule to validate model critical path will also be provided.2019Risk
Risk: Intentional Interaction With UncertaintyKai Lemay, Raymond Britt, Jessica LaitiIn this session we review how Risk Management is too often perceived as a compliance exercise rather than a management tool. Because of this outlook, the vast majority of risk registers record too few risks. The limitations and pitfalls of restricting the amount of risks recorded leads to a reliance on point estimates, an incomplete risk mitigation plan, and an absence of tangible impacts and analysis. Its not the big risk that lead your project to failure, its the 30 little risks that occur in a unique sequence of events that spirals into a perfect storm.2019Risk
Adapting Existing Cost Model to Estimate Section 804 Rapid Prototyping and RapidRick Garcia, Jesse CelisAnalogous prototype program cost data doesnt readily exist and the development of prototype specific cost databases is a lengthy process. Our immediate Cost Estimating needs must address estimating prototype satellites using existing cost models. Our evolving process elicits and applies explicit cost model adjustments to existing cost models to directly address the explicit differences between prototypes and operational systems, specifically in the areas of CERs to Model Commercial-Like Programs and %New Design and Heritage.2019Space & Missiles
The Efficacy of NASA's Joint Confidence Level PolicyAndy PrinceIn January 2009 NASA policy established the performance of a Joint Cost Schedule Confidence Level (JCL) analysis as the basis for project funding and external commitments. This paper examines the efficacy of that policy relative to reducing cost overruns. Projects executed before the policy implementation are compared to projects approved post-policy implementation. Various statistical techniques are used to perform comparative analyses and alternative explanations are explored.2019Space & Missiles

An Analytical Explanation for Vertical Integration Behavior in the MarketplaceCaleb Williams, Jack SemrauVertical integration is a costly and difficult-to-reverse strategy with significant risks, yet it has experienced a sharp rise in popularity within the satellite sector over the last decade. Building on previous research, this session demonstrates how commercial parametric tools can be used in combination with business-case analysis to understand why aerospace companies are increasingly pursuing vertical integration strategies. Additionally, it discusses how the framework for this analysis can be applied across other industries.2019Space & Missiles
Estimating Missile G&C Development Cost: An Important AdvanceJames York, Paul Hardin III, Jeffery Cherwonik, Olivia CollinsThis paper describes improved cost estimating methodologies for tactical missile Guidance and Control (G&C) Development Engineering (DE), generally the largest contributor to missile development cost and typically one of the most challenging cost elements to estimate. These methodologies represent an alternative approach to commonly used cost factors (e.g., factor of prototype production cost) which have error metrics that normally exceed 50%. The research developed CERs with error metrics below 50% and as low as 20%.2019Space & Missiles
A Comparative Analysis of Nuclear Security Enterprise Estimates.Terry Josserand, Leone Young, Wendy LeeVarious government publications recommended adapting multiple methods and approaches to enhance the quality, validity and reliability of a program cost estimate. This study utilizes a COTS software tool and two approaches based on different system architectures, for a Nuclear Security Enterprise estimating effort. The cost estimate results exhibit a phenomenon of near-homogeneity. Model techniques, critical parameters, and cost drivers are analyzed and evaluated to help comprehend the model behaviors.2019Space & Missiles
Impact of Scope Changes on Schedule GrowthDaniel Bowers, Geoffrey Driskell, Gail Flynn, Kelsey AndersonCan cost analysts predict and thus estimate schedule growth based on scope changes? Is there a relationship between the two? Leveraging from the same research and data as the 2018 ICEAA Workshop paper ‚“Impact of Scope Changes on Software Growth‚ by Jonathan Brown and Gail Flynn, this research focuses on the possible schedule impacts due to pure growth and scope changes. Analysis was performed from a scheduling perspective to show the impact scope changes can have on the program schedule.2019Scheduling & Programming

The Journey to Better ERP EstimationJon Kilgore, Jenna Meyers, Arlene Minkiewicz, Cara CuiuleSoftware estimation is never easy, especially when implementing large complicated Enterprise Resource Planning (ERP) Systems comprised of significant off-the-shelf (OTS) components combined with glue code interfaces to numerous legacy systems. Data to support such an estimate is sparse, incomplete, and often inconsistent. This paper presents the first phase of a journey toward improvements to this situation, utilizing analysis of historical data to inform future estimates, focusing on process and lessons learned.2019Software
Software Cost Estimation ‚¬ Why Is It Different?Harold van HeeringenSoftware Cost Estimation is often considered the most difficult part of an integral cost estimate. Unrealistic software estimates often result in disasters. Examples are new tunnels, metro lines or factories that cant start their operation because everything is ready, except for the software part. One of the main reasons for this is often an inaccurate and optimistic software cost (and schedule) estimate. Why is estimating software differently and how is ICEAA dealing with this?2019Software
In Search of the Production Steady State: Mission Impossible?Patrick McCarthyLearning Curves are a vital tool for cost estimators when predicting the number of direct labor hours required for a production run.

Using Real Options to Quantify Portfolio Value in Business CasesGeorge Bayer, With the challenges in quantifying program risks, interdependencies, and the business case impact on portfolios, cost estimators can use real options to estimate probabilistic value in business cases and assess portfolio value. Many business cases not only add value as stand-alone investments, but they provide the opportunity for subsequent investments. Cost estimators can measure this incremental program value and the impact of a specific investment on a larger portfolio by using real options.2017Economic Analysis
Discount Rate for Government InvestmentRon Beheler, Laura BarkerWe often use a discounted-cash-flow construct to evaluate the Economic Viability of an investment. OMB-94 provides discount-rate guidance for internal investment (treasury rates) and public investment/regulatory programs (7% - rate of return on an average private sector investment). Since any resources consumed by the government must be foregone by the private sector, we will argue that the discount rate should be based on a rate that at least proxies the value of private investment.2017Economic Analysis
Are the Rates Right? Benchmark Protection Against Escalation SWAGBrian Flynn, Brian Torgersen, Greg Mihalek, Adam JamesMedical escalation rates continue to trend higher than general inflation - with significant impact on defense firms and acquisition affordability. Modest deltas in rates translate into billions of additional costs. This research presents benchmark escalation values for employer costs of employee medical compensation. The benchmarks, in turn, support company planning & collective bargaining and liberate government cost estimates from their traditional reliance on solely FPRPs and FPRAs.2017Economic Analysis
The Rate You Want ‚“ Rethinking Cost Escalation in FAA DevelopmentSriram Krishnan, Andrew DrennonLike most civilian agencies, the FAA has used 'raw' OMB escalation indices to produce then-year costs for its life cycle cost estimates. However, as an agency which incrementally funds many development programs, could the FAA benefit from recognizing time value of money principles at the estimation stage? We look at outlay data from across the agency to determine whether defense appropriations styled weighted indexes would significantly impact then-year FAA solution development costs.2017Economic Analysis

This presentation discusses a systematic approach to tailoring DoD best practices for non-DoD acquisition needs.2017EVM & Scheduling
Cost Associated with Acquisition Complexity and Differing Levels of Mission AssuranceErik BurgessIn Government acquisition programs, the cost of what we buy is largely driven by how we buy. For satellites, this includes contracting, funding, oversight, reporting, testing, parts assurance requirements, and other factors. All of these are related, and no single attribute defines the cost curve. The NRO has developed and implemented a method that quantifies the cost of these factors and circumvents the usual debate about whether or not an acquisition is streamlined or commercial-like.2017Methods

Data Driven Confidence Regions for Cost Estimating RelationshipsChristopher JarvisCost estimating models typically contain many uncertain parameters. The uncertainty of the parameter values drives the uncertainty of the model outputs. In this paper we review and compare the techniques to compute the confidence regions for linear and nonlinear regression methods. Application to two common CERs is presented with comments regarding the practical implementations and limitations within the current cost estimating environment.2017Parametrics
Moment One, PleaseChad Krause, Erik BurgessCost models constructed without statistical correlation are designed to underestimate the mean, unless they are simple sums. Any model that uses a factor or other instance so functional correlation will miss the first moment, not to mention others, unless statistical correlation among the CERs is also applied. An internal audit of 13 recent satellite cost estimates comprising of 52 CERs shows the mean cost changes by as much as 9% when this correlation is applied.2017Parametrics
Modeling with Gumby: Pros and Cons of the Weibull CurveMichael Mender, Ann HawpeThe Weibull function is used to model various cost phenomena. This popularity is driven by its significant flexibility, driven by its nature as a two parameter function. Additional parameters result in flexibility, which while advantageous, also places incorporating estimates at risk of over fitting (i.e., a model that fits the observed data well, but has little predictive power). Presentation relays theory and exhaustively reviews pros and cons for cost estimating.2017Parametrics
Maximum Likelihood Estimation for Regression of Log Normal ErrorChristian SmartThe use of Log-transformed Ordinary Least Squares (LOLS) has been criticized for the use of transformation, which results in biased estimates. LOLS is a maximum likelihood estimate (MLE) of the median when the residuals are lognormally distributed, for which we provide evidence. We discuss MLE and show how to use this technique to directly model untransformed lognormal error. We also discuss two other popular methods, ZMPE and MUPE, in the context of MLEs.2017Parametrics

A 'Common Risk Factor' Method to Estimate Correlations Between DistributionsMarc GreenbergA 'common risk factor' method uses expert-derived risk factors to estimate correlation between two distributions. The premise is to estimate mutual information among risk factors that underlie each distribution. Approximation of such mutual information leverages properties of the joint probability distribution of a unit square. Geometric outputs of each pair of common random variables are compared to estimate common risk factor 'intersections' that are, in turn, proxies of correlation.2017Risk
The End of S-Curve Alchemy: Gold from a New SAR DatabaseTodd Andrews, Jeffrey Pincus, Brian FlynnS-curves typically address only "known unknowns." They're built upon an analysis of cost risk and uncertainty‚“ element by element. But, they fail to address the ambiguity of the curve itself, or the degree of confidence that its proffered probabilities are actually correct. This confidence factor, of course, is hard to measure. The "unknown unknowns," in other words, are not explicitly captured since their probabilities are a mystery. This research fills the gap in knowledge.2017Risk
Being Certain About Uncertainty, Part 1Andy PrinceDoing cost risk analysis is hard because we don't really know what a good cost risk analysis looks like.

Predictive Thresholds for Schedule Execution MetricsMichelle JonesWe called it the search for a unicorn. After an intense week of schedule analysis, checking the numbers, updating visual basic code, then presenting objective evidence that the contractor is not achieving the baseline plan, we got the action: provide the metrics of a good program. We tried, but after reviewing countless schedules, we realized that a "good" program is as rare as a unicorn, because every program deviates from the baseline plan. Although we never found a unicorn ("good program" with good metrics), we developed data driven thresholds predictive of significant milestone slip.2022Processes & Best Practices
The BS in BoeS – Oh the Games that are PlayedSandy BurneyA good Basis of Estimate (BoE) uses a historical comparison, and a complexity factor. These two choices are not statistically based, meaning a bias is introduced into most BoEs. This paper explores the bias in BoEs through the framework of Game Theory. A BoE goes through a creation, internal review, internal approval, and external review process, where each player in this process will likely have a different payoff matrix. Each player in this process will want to insert their bias into the BoE, which this paper terms “Bias Selectivity” (BS).2022Processes & Best Practices

Estimating Costs of Climate Change Impacts to Public Infrastructure (CIPI)Edward Crummey, Nicolas RhodesWhat is the long-term budgetary cost that certain climate change hazards could impose on public infrastructure in Ontario, through accelerated deterioration, increased operating expenses or compromised service levels? CIPI combines climate data with mapped infrastructure data, and applies a derived climate "elasticity" to cost the impact of specific climate hazards. While quantifying the budgetary impacts of climate change on public infrastructure is relatively new, the methodology could support capital funding decisions and adaptation actions by governments now and in the future.2022Trending Topics
Superheavy Launch: The Coming Paradigm Shift for the Space IndustryRyan TimmA new generation of superheavy launch vehicles will provide mass and volume capabilities not available in the last 50 years. This paper describes how superheavy launch will transform space vehicle (SV) design and the space industry. No longer mass-constrained, SVs will be build with different materials and processes, and will include capabilities previously inconceivable. SV developers will adapt their facilities, logistics, and support equipment. Cost estimators may want to revisit parametric CERs dominated by weight.2022Trending Topics

Establishing Standards as the Basis for Effective Measurement and AffordabilityPete PizzutilloMeasurement of application development output has long been a controversial topic. Yet as contracting relationships within industry and public sector become more strategic, buyers and sellers of software development and sustainment services require consistent and effective measures of application development output to provide: objective visibility into application development output; a rational basis for Application Development and Maintenance (ADM) investment decisions; and vendor and buyer accountability supported by data, not subjective judgments.2018Software Estimating
Integrating Excel Cost Models and MS Project SchedulesMelvin R. Etheridge, Jr.The FAA requires non-risk-adjusted 'resource loaded' schedules as part of its Milestone Decision process. Integrating cost and schedule risk in MS Project schedules and Excel cost models is challenging. These challenges stem from the fundamental differences between a cost estimate, which is a tree, and a schedule, which is a network and the dependency of some cost elements to duration. This paper investigates techniques for linking risk-adjusted schedules and cost estimates. It highlights the need for close collaboration between cost estimators and schedulers.2018Management, EVM & Scheduling
Software Data Collection and Analysis for Proposal EvaluationKen Rhodes, Eric HippensteelSoftware data collection forms provide necessary information for the Government to assess the validity of proposed software development effort, productivity, sizing, and schedule. This paper discusses use of the forms with an RFP to validate contractor proposals and compare across multiple bids. This data collection and evaluation approach helps ensure selection of the best vendor and defend against protests, and was recognized by Defense Procurement and Acquisition Policy (DPAP) as a DoD acquisition best practice.2018Software Estimating
Cost of Software Obsolescence ResolutionsSanathanan RajagopalSoftware plays an important role in defence. Almost every project in defence has software elements with various degrees of complexity and dependencies. This has brought its own challenges to the availability-based contracts. The challenges to both the contractors and the suppliers is that they have to have a good understanding of the whole life cost of the product and have confidence in the whole life cost model at the time of negotiation and contract signing. This paper will look into the ways to estimate the cost of Software Obsolescence resolutions of real-time defence software.2018Software Estimating
Software Made Simple: Effort Adjustment Factors and the Accuracy of the EstimateJeremy GoucherThis research investigates the sensitivity of estimated hours for software development in relation to effort adjustment factors (EAFs). The analysis highlights the importance of performing original data analysis for new estimates, rather than relying on rules of thumb or industry standards. Accuracy and precision metrics are used to demonstrate the applicability of the ESLOC method to a variety of software projects, including agile projects. Finally, the analysis is supported with data from over thirty historic programs.2018Software Estimating
Predicting Maintainability for Software Applications Early in the Life CycleCara CuiuleMaintainability is defined as the difficulty of altering a software system's source code, thus it is tied very closely to the concept of software maintenance. The following research is an investigation of the methods used for measuring this characteristic (including the Maintainability Index). Guidance on how maintainability affects maintenance effort will be proposed. This will be followed by a discussion of which metrics could possibly predict maintainability early in the life cycle.2018Software Estimating
Impact of Scope Changes on Software GrowthJonathan Brown, Gail FlynnThe SEI DoD Software Factbook summarizes MDAP/MAIS SRDR data for DoD programs. The mean value reported for ESLOC growth is 106%. While accurate, the SEI's and other similar analyses capture total software growth, including the impact of scope changes. This paper introduces 'Pure Software Growth' which differentiates planned scope changes from traditional software growth. Several programs are analyzed from this perspective to show the difference between pure and total growth and the unexpected impact this could have on estimates.2018Software Estimating
Enhancing Risk Calibration MethodsChristian B. SmartCalibration methods such as the Enhanced Scenario-Based Method allow analysts to establish cost risk analyses that are based on objective data. Some methods currently in use rely on the normal and two-parameter lognormal. Empirical data, however, indicates that a three-parameter lognormal is more appropriate for modeling cost risk. We discuss three-parameter lognormals and how to calibrate cost risk using this distribution. We compare the results with traditional calibration to two-parameter normal and lognormal distributions.2018Risk & Uncertainty
Calculating a Project's Reserve Dollars from its S-CurveMarc GreenbergA probabilistic method was developed to calculate funds a project would need if it exceeded the project's point estimate. This conditional cost reserve is depicted as the amount of funds held in reserve 'above the project of program. The method requires three data inputs to calculate cost reserve: (1) the project cost dispersion (measured by its coefficient of variation), (2) the project point estimate, and (3) the confidence level of the project point estimate.2018Risk & Uncertainty
Estimating the Cost of Pharmaceuticals: Managing Cost and ExpectationsThurman D. Gardner, Robert HuntRecently headlines have been addressing the high price of pharmaceuticals. Contrary to what it may seem, greed does not drive pricing, it is the unknown and recovery of costs. Science provides a big piece of this, but the regulatory pathway is almost as big a factor, and in some cases bigger. Estimating new products requires a solid methodology and forward-thinking approaches to adequately bound projected costs and expectations.2018Risk & Uncertainty
Risk-Adjusted Contract Price MethodologyPeter J. Braxton, Keith S. Hetrick, Orly S. OlbumTraditional risk approaches rely on program-level risk and uncertainty benchmarks from SARs, but governments and other buyers need to assess and manage risk at the contract level.

Demand, Recurring Costs, And ProfitabilityDouglas K. HowarthCustomers in all markets collectively abide by their self-imposed demand curves, which dictate their responsiveness to changes in price and the maximum quantities of products they can absorb. Concurrently, producers in all markets face recurring costs, which typically fall over time due to a variety of factors. Producers can effectively model demand and recurring costs before product launch. Understanding how demand curves relate to recurring costs is key to enhancing profitability, which this paper examines.2018Economic/Data Analysis

Robust Non-Design, Code, Test, and Integration Cost Estimating RelationshipsBritt Staley, Nicole RobertsonComputer program development (CPDEV) models are founded in accurately estimating the design, code, test, and integration (DCTI) of the computer program. Given that non-DCTI support costs can account for 50 percent or more of the estimate total, it is also critical to accurately capture these indirect costs. This paper analyses almost two decades of historic data from nineteen CPDEV efforts to derived timely non-DCTI cost estimating relationships for use in these types of estimates.2018Economic/Data Analysis
Calibrating Use Case Points Using Bayesian AnalysisKan Qi, Anandi Hira, Elaine Venson, Barry BoehmUse Case Points (UCPs) has been widely used to estimate software size for object-oriented projects. Yet, many research papers criticize the UCPs methodology for not being verified and validated with data, leading to inaccurate size estimates. This paper explores the use of Bayesian Analysis to calibrate the use case complexity weights of the UCPs method to improve size and effort estimates. Bayesian Analysis integrates prior information (in this study, we use the weights defined by the UCPs method and the weights suggested by other research papers) with parameter values suggested by data. The effectiveness of the calibration approach has been evaluated by our empirical study of 34 use case driven projects. We found that the Bayesian estimates of the use case complexity weights consistently provide better estimation accuracy compared to the weights proposed by the original UCPs method, the empirically calibrated weights, and the expert-based weights.2018Economic/Data Analysis

A Case Study for Future Munition: An Analysis of AlternativesFaye Kim, Meagan GadreaultAn Analysis of Alternatives (AoA) is essential in making a rational funding decision particularly before MS A decisions. An AoA was conducted to determine the Total Ownership Costs (TOC) for 21 possible Courses of Actions (COAs) for the design of a future munition. Multiple options within the future munition's three main hardware sections and software section create the COAs, and differences in these options within the COAs drive the TOC that impact the overall AoA decision.2018Economic/Data Analysis
Projecting Future Costs with Improvement Curves: Perils and PitfallsBrent M. JohnstoneImprovement curves are one of the most common projection tools used by cost estimators. Their use is surrounded however by perils and pitfalls. Common errors include: the fallacy of 'straight edge and graph paper' projection, the dangers of recovery slopes, failure to understand how development and production environments differ, and the dangers of using learning curve slopes to measure production line efficiency. This paper examines these potential pitfalls and proposes ways to avoid them.2018Economic/Data Analysis
Diamonds in the Rough: How to Normalize Cost Accounting DataNiatika Griffin, Jason DeLorenzoEvery government agency has a cost accounting system. For cost estimation purposes, this is a wealth of actual cost data that can be used as a reference for estimates. Unfortunately, the needs of financial analysts differ from cost analysts. This paper explores how to normalize cost accounting system data using FAA's Delphi system as a case study. We conclude given certain assumptions the data can be normalized into usable source data and customized reports.2018Economic/Data Analysis

Potential Impacts of Non-Major Program Data Collection on Cost EstimatingBrandon S. Bryant, Stephanie MyrickThe FY 2017 NDAA requires the armed services to collect cost data on all acquisition programs over $ 100 M. The requirement creates a challenge of balancing data collection standardization and flexibility for programs that have not been required to follow traditional data collection strategies. However, this new requirement is an opportunity to improve DOD cost analysis. This paper provides implementation strategies, how to leverage current data collection tools, and potential impacts on cost estimating.2018Acquisition & Operations
The Concepts of Size and Productivity in an Agile WorldHarold van HeeringenMany organizations have moved to agile development software development. One of the cornerstones of one of the main Agile methods, Scrum, is to de-professionalize estimation and to use an arbitrary effort unit of measurement, the story point, to estimate projects. Because of a lack of understanding of the matter, management in these organizations believe that this is the way to go, but now they are facing huge challenges in estimation and budgeting. it is explained why agile has resulted in lower estimation maturity in the industry, and the ways this can change again using industry standards.2018Agile

Beyond the Matrix – The Quantitative Cost and Schedule Risk ImperativeChristian B. SmartThe first step in risk management is gaining an appreciation for risk and uncertainty. However, despite a long history of cost and schedule growth in all types of projects, we tend to focus on averages rather than recognize extremes. Project management is blind to risk. The fixation on averages leads to an underestimation of risk. The use of qualitative methods, including risk matrices, is prevalent, but should be analyzed with rigorous quantitative methods.2021Analytical Methods

Facilities Cost Estimates Drivers in the Oil and Gas Field DevelopmentLinda Newnes, David Peacock, Ettore Settani, Jon WrightIn aerospace and defence research has focused on estimating the cost of delivering an outcome, e.g. available aircraft. Our research shows that focusing on the product alone, using product reliability/failures does not reflect the cost of delivering an outcome. In this paper we show why this is the case and how the use of input-output modelling and systems engineering can be used. We then demonstrate how the approach can be used in estimating the cost of waste water treatment.2016 Int'lModels & Methods

NASA's X-Plane Database and Parametric Cost Model V2.0Steve SterkIn 2015 the idea of creating an Armstrong X-Plane Cost Model was conceived. Initially the data being used was leveraged from Dr. Joe Hamaker's Quick Cost v5.0 and verified and supplemented by Armstrong's summer intern Aaron McAtee (PhD). After several peer reviews, it was suggested to go back and take a hard look at the data collected. Our objective is to produce an X-plane database that ensures that all the data is as accurate, traceable and far-reaching as possible.2016 Int'lGovernment Perspectives

Preventing Program Management Pitfall Using Portfolio EstimatingNick Morales, Christopher DewberryEstimating the effort, time, and resources needed to complete project activities is one of the most challenging tasks that project managers must face. Along with the inherent uncertainty associated with managing these activities, additional management uncertainty occurs when there are multiple incremental efforts associated with that project. In order to handle the complication of managing several program increments, each with their own budget lines, portfolio estimating is a method that helps to provide program managers with a fully comprehensive overview of the resource requirements across multiple projects. Program managers can use the portfolio estimate as a tool to help make informed management decisions at the appropriate level and identify how those decisions impact the entire program.2016Management, EVM & Scheduling

Fixing the Flawed Nature of DoD BCA'sWilliam G. WilliamsonThe government is not a business that is profit-oriented. Monetary business metrics as a means of determining what items to consume are inherently flawed for the government since metrics such as Return on Investment's assume the organization is a provider of the goods or services, not a consumer. A better approach for the government would be to measure the areas that the government most values, i.e. schedule and requirements. Using those areas as anchors, a best value metric can be developed, pointing the government to smarter acquisition decisions.2016Business Case Analysis
Developing a Dynamic Expense-Volume-Profit Model to Determine Break-Even pointWilliam KentAnalysts must be able to determine when a program will be profitable. This insight is used to drive contract negotiation, pricing, and strategy. Many factors need to be evaluated: expenses, revenue, and volume of sales. These factors must be determined based on limited historical data and extrapolated over a time horizon. This paper introduces a framework for analyzing these factors using learning curves, regression, and financial statement analysis to determine break-even.2016Business Case Analysis
ROS vs. ROC: Government Can Lower Price by Raising FeeSandy BurneyMany Government Contractors measure profitability using Return on Sales (ROS), which includes Fee in the denominator.

Cost Risk for Firm Fixed-Price ContractsDavid Biron, Christian SmartThe terms "cost risk" and "firm fixed-price contracts" seem contradictory. By design the contractor bears all risk under a firm fixed-price (FFP) contract. In spite of this, overruns often occur, and contractors have recourse to a Request for Equitable Adjustment (REA) when cost grows beyond the contract value. We present statistics on cost overruns for FFP contracts, some of which are significant, and show how to model risk for such contracts.2016Risk & Uncertainty
Modeling Prediction Intervals Using Monte Carlo Simulation SoftwareJames Black, Qing Qing "Q" Wu, The use of a prediction interval (PI) is a simple method of quantifying risk and uncertainty for a Cost Estimating Relationship (CER) derived from an Ordinary Least Squares (OLS) regression.

This presentation will provide a step-by-step tutorial for modeling a PI for an example CER using Monte Carlo Simulation software and will identify the beneficial impact on the coefficient of variation (CV).2016Risk & Uncertainty
Introducing RIFT to Protect Your Uncertain ScheduleNicholas DeTore, Peter FredericThere are industry-accepted methods for allocating cost risk and uncertainty analysis results to detailed WBS elements; schedule results cannot be allocated the same way since duration behaves differently than cost. We present an innovative solution to this issue. The RIFT algorithm calculates a threshold date, for any task or milestone, that if exceeded puts the probabilistic project finish date in jeopardy. RIFT provides a new tangible metric to guide decision makers.2016Risk & Uncertainty
Risk vs. Uncertainty - What's the difference?Melvin R. Etheridge, Jr.After years of applying "risk", many in the profession still do not understand the difference between program risk and cost uncertainty in cost estimates. Determining confidence levels goes beyond simply applying the effects of programmatic risks. Simply put, risks have a probability of occurrence, while we know that quantitative inputs have some degree of uncertainty and must be treated as random variables. This paper explores analytical methods in Excel-based cost models using Monte Carlo s2016Risk & Uncertainty
A 'Common Risk Factor' Method to Estimate Correlations between DistributionsMarc GreenbergA 'common risk factor' method uses expert-derived risk factors to estimate correlation between two distributions. The premise is to estimate mutual information among risk factors that underlie each distribution. Approximation of such mutual information leverages properties of the joint probability distribution of a unit square. Geometric outputs of each pair of common random variables are compared to estimate common risk factor "intersections" that are, in turn, proxies of correlation.2016Risk & Uncertainty
How Regression Methods Impact Uncertainty ResultsBoyan Jonov, Shu-Ping Hu, Log transformation and weighted least squares are commonly used to develop multiplicative error cost estimating relationships. We objectively compare the two regression techniques and provide a sound defense of log-linear ordinary least squares (LOLS) to counter arguments against its use. We then demonstrate how uncertainty modeling varies substantially based on regression method. Lastly, we establish criteria to use so that LOLS leads to a justifiable uncertainty assignment.2016Risk & Uncertainty
The Zone System of Uncertainty AnalysisJeff McDowellThis paper presents a methodology for selecting cost uncertainty distributions and their dispersion inspired by the photography Zone System. The method seamlessly addresses five groupings of uncertainty across a sliding complexity scale. The distribution shapes and their parameters are drawn from patterns developed from the AFCAA Cost Risk and Uncertainly Metrics Manual (CRUAMM) body of work.2016Risk & Uncertainty
Cloud Total Ownership Costing: Considering the Technologies, Costs and BenefitsDan Galorath, Steven WoodwardCloud abounds with promises of drastically reduced costs, which are all attractive. However, Cloud computing can be ineffective in terms of technology, affordability and total cost of ownership in many situations. The assumption that cloud technology reduces government costs is often flawed. The benefits from cloud computing relating to time-to-market, savings, innovation and agility should be analyzed, providing balanced perspectives for the cloud opportunities presented.2016Software & IT
Data Collection for Agile ProjectsBlaze SmallwoodAgile software development projects produce a unique set of metrics, such as points and velocity, that can provide interesting insight into project progress. However, collecting this data requires specialized mechanisms, since no established standards exist, like SRDRs.

Estimating Small Scale Software Integration Efforts with a Large Scale Code BaseJoe BauerEstimating the cost and effort for testing and integration is often one of the most challenging aspects of software estimation. Integration effort depends greatly on the components under evaluation. When relatively small capabilities are introduced into large existing code bases, the integration impact due to the existing code may surprise stakeholders even when requirements are reduced. This presentation highlights software integration modeling for a major defense acquisition program.2016Software Sizing
Alternatives to SLOC in the Modern EnvironmentJeremy GoucherSource Lines of Code (SLOC) based estimating relies heavily on subject matter expert input. However, viable alternatives to SLOC are few. By mapping deliverables to functionality and functionality to effort, the authors propose an alternate technique with reduced reliance on SLOC. Agile development and some recent innovations represent alternatives as well. The authors will present an overview of the topic with examples, required data inputs, and estimating methodology.2016Software Sizing
Agile and Function Points: A Winning CombinationDaniel B. FrenchMany users of Agile have an incorrect belief that projects do not need to adhere to proper project management practices. However, it doesn't advocate getting rid of metrics or PM processes. The most critical aspect of software development is software size. Function Points can be effectively used with Agile development and this presentation will demonstrate the benefits of using FP in many aspects of project management including estimation, schedule and product backlog.2016Software Sizing
Cost Element Structure for Cloud Migration Business Case AnalysisLorena AguilarIn 2010, the White House released its initial "cloud first" policy. Agencies have since struggled to identify all of the costs associated with cloud migration, and recent audits have criticized agencies for not properly assessing cloud-related costs and benefits. We have developed a cloud migration cost element structure (CES), which simplifies and standardizes cost data collection and estimating. We will present the structure and its applicability to business case and cost benefit analyses.2016Software Sizing
Collaborative Scoring: An Innovative Approach for Sizing Software ProjectsBlaze SmallwoodA major challenge facing government organizations is developing defendable cost and schedule estimates for software development projects, driven by adequately estimating software size.

Building an Integrated Aerospace Electronics Development Parametric Model from the Ground UpDavid BloomThis paper presents the results of a multiple year effort to create a business specific set of integrated parametric cost models for complex electronics hardware development in such a way that all disciplines and activities that participate in that development process have a piece of the model and a stake in the data collection that drives the model. This "grounds up" approach provides that added benefit of cost allocation guidance once the development is approved.2016Parametrics
Essential Views of the Integrated Program Management Reports (IPMRs)Thomas Coonce, Glen AllemanDuring this session, the authors will describe key views of the IPMRs and other data that will allow a government stakeholder to a) understand the cost, schedule and technical status on applicable contracts, b) investigate the nexus of performance problems, and c) observe likely future problems. The presentation represents a "synthesis" of existing traditional earned value management metrics and other metrics designed to provide an integrative picture to assist in keeping the program "green".2016Program Management
Meeting Fiscal Constraints: the Evolving Role of Performance MeasurementSteve Green, Kevin Davis, Kurt Heppard Performance measurement tools can reflect the strategic intent of management and help them prioritize initiatives to meet strategic objectives. In fiscally austere times, the Balanced Scorecard can help organizations address these tough decisions. Applying concepts from the Balanced Scorecard to cost analysis and budgeting, this paper develops an integrated aligned system of strategic goals, performance metrics, and cost parameters at a university facing pressure to manage costs. There may be lessons learned for the DoD.2016Program Management
The graph is always greener on the other side: examples of how to interpret and fix bad visual representations of dataStephen KetchamIn my role performing independent reviews of estimates, I've seen a quality spectrum of different types of graphs, charts, and forecasts. These visuals summarize key points and remain in decision-makers minds, often providing the convincing point to win funding approval for the project. Unfortunately they can also be poorly crafted, employ scare tactics or even frame the data in a misleading way. This presentation provides bad examples of visuals, and discusses possible improvements.2016Program Management
Seeing What We Need to See vs. What We Hope to See: Visualizing Integrated Cost and Schedule Data for Earned Value AnalysisBrian LeachWhen applied properly, data visualization can serve analysis by showing us what is otherwise difficult to see (and not always what we hope to see). With the emergence of the UN/CEFACT XML standard, integrated cost and schedule data can be shown in exciting new ways. This paper will examine and explore innovative new ways to show integrated cost and schedule data which have practical applications in earned value management system analysis.2016Program Management
Different Incentives in Government ContractingJennifer LeottaThis paper shows stock prices are used as the primary incentive for executives of publicly traded government contractors rather than profit sharing contracts. Looking at the reaction of companies' stock prices to public and private sector news, this paper shows stock prices do not capture "bad news" for both the public and private sector customers compared to overall market indicators; and would make poor contract incentives. Finally, alternate methods of contract incentives will be explored.2016Program Management
Agile Project Management Controls: Issues with EVM and a Viable AlternativeOmar Mahmoud, Blaze SmallwoodAs more government software programs adopt agile practices, program managers are trying to find effective ways to monitor and control cost and schedule. The challenge is that traditional project control techniques, like EVM, are not well suited to deal with the requirements fluidity and new terms/metrics that come with agile projects. This paper will describe the inherent issues with using EVM on agile projects and offer a recommendation for a more effective solution.2016Program Management
The Psychology of Cost EstimatingAndy PrinceResearch into human psychology has yielded amazing findings into how we process information and how we use information to make decisions. Cost estimators can use psychology and behavioral economics to improve not only our cost estimates but how we communicate and work with our customers. By understanding how our customer's think, and more importantly, why they think the way they do, we can have more productive relationships and greater influence. The end result will be better decisions by the decision makers.2016Program Management
Cost ManagementGeorges TeologlouCost Management has a key role in project management and is the management trend due to the actual financial and economic worldwide constraints. Cost Management solution was built to be in line with the recommendations of the GAO (US Government Accountability Office) that stated that a large number of Defense projects are at risk of experiencing cost overruns and schedule delays. GAO found that the two major causes of project failure were first an inaccurate initial estimate and secondly poor subsequent cost control.2016Program Management
Using Total Lifecycle Cost as the Basis for Proposal Cost EvaluationRyan TimmThis paper discusses benefits and obstacles of using the TLCC of an entire system instead of the bid price for the purpose of proposal cost evaluation. An example acquisition of a space vehicle (SV) ground system explains the impact to TLCC of portions of the ground system developed by the SV manufacturer, SV operations, external software interfaces, government furnished IT infrastructure, and legacy sustainment until transition. Using TLCC allows higher-level requirements and enables innovative architectures.2016Program Management

It also delivers tips and tricks on how to make an estimate presentation more visually pleasing and easier to understand.2016Program Management
Using Stochastic Optimization to Improve Risk PrioritizationEric DrukerMinimizing the cost of complex programs is critical for government agencies trying to meet their missions in today's fiscal. Today, identifying cost-savings measures is a manual procedure where an analyst must make an educated guess as to what risks to mitigate. This process is manual and slow. This paper will outline a methodology for using the emerging field of stochastic optimization to automate the identification of cost-savings measures on complex programs.2016Risk
Why Are Estimates Always Wrong: Estimation Bias and Strategic MisestimationDan GalorathThe biggest source of estimation error usually comes from people, either by accident or strategically. This is a disaster because viable estimates are core to project success as well as ROI determination and other decision making. Most people don't know how to estimate. Those who estimate are often optimistic, full of unintentional bias and sometimes strategically mis-estimating. This paper discusses the issues of estimation bias and strategic mis-estimation as well as how to mitigate these issues.2016Risk
A "Common Risk Factor" Method to Estimate Correlations between DistributionsMarc GreenbergA "common risk factor" method uses expert-derived risk factors to estimate correlation between two distributions. The premise is to estimate mutual information among risk factors that underlie each distribution. Approximation of such mutual information leverages properties of the joint probability distribution of a unit square. Geometric outputs of each pair of common random variables are compared leading to an estimated 'intersection' of pair of common risk factors. This intersection is then assumed to be a proxy of correlation.2016Risk
Data-Driven Guidelines for Correlation of Cost and Schedule GrowthSidi Huang, Mark Pedigo, Chris Shaw When running Monte Carlo simulations, one of the most difficult aspects to account for is correlation between the independent variables. Ignoring correlation generally reports overly optimistic analysis results; industry standard suggests that when no additional insight is available, a default value of 0.2 can be used. This study analyzes historical NASA program data to develop data-driven guidelines for correlation. Moving forward, this study can be replicated to other industries and organizations with critical schedules.2016Risk
Risk Mitigation: Some Good News after the Cost / Schedule Risk Analysis ResultsDavid HulettThe results of your cost-schedule risk analysis say you are likely to be overrun on both schedule and budget. Are you are out-of-luck? No. Do not forget the risk mitigation phase. Risk mitigation typically proceeds from a prioritized risk list developed from analysis of the risk and uncertainty-loaded schedule. Complete mitigation of risks is not usually feasible, and uncertainty is usually deemed to be irreducible. Some good news comes from the risk mitigation actions.2016Risk
A Mathematical Approach for Cost and Schedule Risk AttributionFred KuoThe level of sophistication in cost estimate has progressed substantially in the last decade. This is especially true at NASA where, spearheaded by the Cost Analysis Division (CAD) of NASA Headquarters, cost and schedule risks in terms of confidence level have been codified. In this paper, the author attempts to employ the portfolio approach in calculating risk attribution; first applying to a portfolio of cost risks and extend the same concept to schedule risks analysis.2016Risk
Triangular Distributions and CorrelationsJennifer LampeTriangular distributions are often used in estimating cost risk because the math is relatively simple. The concept of an estimate having a lower limit, an upper limit, and a mode is easy to understand. We show the math behind triangular distributions and correlations. What does it mean to say that two risks are 30% correlated? How do risk analysis programs handle triangular distributions and correlations? How can you use random numbers in Excel to generate a Monte Carlo simulation for any defined triangular distribution?2016Risk
The Impact of Selected Assumptions and Core Tenets on Schedule Risk Assessment Results (A Progressive Model Comparison)James QuilliamIn the quest to ensure the sound representation of Schedule risk assessment (SRA) simulations this case study will provide a progressive model comparison of schedule risk assessment assumptions and core tenets.

This will greatly enhance the understanding and confidence that leadership and project teams have in the schedule risk assessment results.2016Risk
Wine as a Financial InvestementMichael Shortell, Adiam WoldetensaeThe purpose of this presentation is to look into wine as an investment and analyze its characteristics as a financial asset. The goal here is to look into vintage wines through time, analyze its profitability and predict how investing in wine could be a good source of diversification. Our objective is to detect the types of wines that are a good source of investment and their associated risk. We aim to identify a good investment portfolio for a wine collector in order to maximize returns and minimize the associated risk.2016Risk
Beyond Correlation: Don't Use the Formula That Killed Wall StreetChristian SmartRisk models in cost estimating almost exclusively rely on correlation as a measure of dependency. Correlation is only one measure (among many) of stochastic dependency. It ignores the effect of tail dependency, when one extreme event affects others. This leads to potential outcomes that do not make sense such as a program with a large schedule overrun but no cost overrun. This method has been widely blamed for the financial crisis a few years ago. The copula method is introduced as a way to overcome these deficiencies.2016Risk
Connecting the Dots: Integrating the risk cube with the POEChristina SnyderDoD guidance instructs program managers to include risk and uncertainty analysis in their cost estimates. Program managers also maintain a risk cube that tracks known program risks and assigns a likelihood and consequence. Risks, regardless of if they are programmatic, technical, or schedule defined, will have an effect on the overall program cost. This paper investigates the linkage between identified risks and POE cost and shows how to translate the risk cube into dollars.2016Risk

Agile Estimation Using Functional MetricsThomas CagleyAgile methods have matured and are now being integrated into many different approaches to the development of software. Estimation has been problematic for all methods, agile to plan based and therefore it tends to be a lightning rod for experimentation and synthesis such as is being described in this paper. Agile Estimation Using Functional Metrics has presented a path for integrating the discipline found in functional metrics with the collaborative approaches found in agile parametric estimation.2016Software Estimating
Put some SNAP in your estimating modelDavid LambertAn effective estimating model is dependent upon having the capacity to accurately size the problem domain for the solution being developed. Function Point Analysis is a widely accepted industry and ISO standard for sizing functional requirements; however, it does not take into account the sizing of non-functional requirements. Learn how the newly released Software Non-Functional Assessment Process (SNAP) can provide a more complete and accurate assessment of project size.2016Software Estimating
Forecasting Software MaintenanceAlea DeSantisProviding a defensible estimate for software maintenance can be complicated. By overlaying historical data with lifecycle events one can derive event driven factors and use trend analysis to forecast future Software Problem Reports. Topics addressed are: common-cause variation, special-cause variation, severity level, complexity level, and decay rate. This method moves away from using a general defect rate calculation to a more complete product-specific calculation.2016Software Estimating
Effective use of Function Points for Analogous Software EstimationDaniel FrenchAnalogous estimation is often used to estimate software projects, especially in the early phases, because it is believed to be quicker and easier than other techniques. However, many organizations do not employ this technique effectively and correctly. One pitfall is improperly applying the technique & basing these estimates on Software Lines of Code (SLOC). This presentation will discuss common mistakes made when using analogous estimates as well as how the use of IFPUG function points can greatly improve this estimation technique2016Software Estimating
NASA Software Cost Estimation Model: An Analogy Based Estimation MethodJairus HihnSoftware development activities are notorious for their cost growth.

Facilitating Predictive Cost Analytics via Modelling V&VJohn SwarenWe are often asked to "fine tune" estimating software to unique situations. That "calibration" effort is key to Verification & Validation of parametric models. In this presentation, we show an example of using Predictive Analytics to develop a method to predict a Software-estimating model's inputs as a function of Key Performance Parameters (KPPs). We demonstrate how a calibrated knowledgebase can best be used to V&V an estimating approach reflective of past and future requirement metrics.2016Government Processes
Hyperbolic Discounting and Defense AcquisitionsEric LofgrenCost estimation has largely been approached as an engineering problem which can be solved using data and techniques. While these are undoubtedly invaluable considerations, the broader production process is an inherently open-ended system subject to human interactions which are ill-defined and non-deterministic. This paper explores how behavior and institutions affect cost outcomes through the avenue of hyperbolic discounting, a time-inconsistent model of personal valuations. It will be argued that evidence for hyperbolic discounting in both government agents and contractor management have negative effects on cost estimates and will proffer some solutions based on commitment schemes.2016Government Processes
Cost Estimating Challenges in Additive ManufacturingJoe Bauer, Patrick MaloneAdditive manufacturing possibilities are virtually endless: from rapid prototyping, to printing food, to recreating human tissue. This presentation highlights the challenges of estimating 3D printing processes and offers some solutions to the estimator. Challenges include: amortizing non-recurring tooling across multiple programs, capturing software-centric nature of 3D printing, printing speed, and printing media limitations. This presentation highlights the use of existing cost estimating tools and areas for future development.2016Methods & Models
Long Term Impact of Ship Concepts on Operating and Support Cost AffordabilityEric Buller, Stuart Merrill, Bryan MillerAchieving affordability can be challenging especially once a program enters full rate production. Developing accurate Operating and Support (O&S) cost estimates that reveal tradeoff impacts and sustainment risks provides decision makers with affordability analysis during key acquisition events. We intend to demonstrate through analysis the impact of legacy and new ship concepts on O&S costs and program affordability. We will examine the cost tradeoffs for each ship concept in each O&S cost element.2016Methods & Models
The Peculiar World of Sole Source Contracting; Maybe There is a Better WaySandy Burney, Shawn LarsonIn 2014, 21% of U.S. Government contracts were sole source, accounting for 31% of total contracted value. They typically require negotiation and certification of all cost estimates, which can take up to 18 months. This light-hearted presentation will explore the peculiar world of developing and negotiating sole source estimates, including differences from budgetary and competitive estimating, as well as offer suggestions for achieving fair and reasonable sole source prices for less time and money.2016Methods & Models

Generalized Degrees of Freedom (GDF)Shu-Ping HuMinimum-Percentage Error/Zero-Percentage Bias (ZMPE) method is commonly used for multiplicative-error models. But ZMPE users do not adjust degrees of freedom (DF) for constraints included in the regression process. This generates misleading ZMPE CER fit statistics and underestimates the CER error distribution variance. Hence, ZMPE results are incomparable with those derived without constraints. This paper details why DF should be adjusted and proposes a Generalized Degrees of Freedom measure to compute fit statistics for constraint-driven CERs.2016Methods & Models
Bottom Up Methods of Estimating Depot Level RepairablesTim Lawless, James Black, Dave GoldbergDepot Level Repairables (DLR) costs comprise a significant share of total Operations and Support costs as they capture the scope of repairing and/or replacing failed hardware items. This paper will provide detailed descriptions of bottom up methods to estimate DLR costs using programmatic technical baseline documentation and acquisition costs as well as supply system requisitions and repair price data sources. Emphasis will be placed on producing data-driven analysis to inform cost estimates and estimate customers.2016Methods & Models
Seven Degrees of Separation: The Importance of High-Quality Contractor Data in Cost EstimatingCrickett PettyThe popular notion that any two people are linked to one another on average via a chain with "six degrees of separation" is based on a relatively small sample. Using massive data sets, researchers have since discovered that the average degrees of separation is closer to seven. This highlights the need for complete and thorough data in any analysis, and cost estimating in particular. Despite its importance the collection of high-quality contractor cost data is challenging. Processes for meeting these challenges are presented.2016Methods & Models
Interviewing Subject Matter ExpertsMelissa TeicherAs estimators, we often have to obtain technical information from Subject Matter Experts (SMEs) in order to provide thorough and accurate analysis. But sometimes, getting the information you need is easier said than done. This paper discusses the steps for interviewing SMEs in order to make the most of their time and your time. It explores the benefits of building a cooperative relationship of mutual respect and the "dos" and "don'ts" of SME consultations.2016Methods & Models
The Impacts of Design Change on Reliability, Maintainability, and Life Cycle CostAndreas Viberg, Oskar Tengo When making decisions about a design change to a technical system, it is essential to understand how it affects reliability and maintainability, as that directly impacts both overall performance and cost of operations and maintenance throughout the life cycle. LCC analysis based on modeling and simulation of relevant scenarios is an effective way to gain that understanding. This paper presents an approach for such analysis and illustrates its successful application in a recent project.2016Methods & Models
A Prime Contractor's View Using JCL Tools and TechniquesChip WoodsFor several years now, Lockheed Martin has been integrating cost and schedule data into a single model to perform integrated analysis.

Class List of Characteristics: Changing the Landscape of Estimating by Removing BiasPaul BreonCLOC (Class List of Characteristics) is a coding system wherein each digit of the code indicates one of the cost drivers for the product/activity. CLOC gives the ability to "Call a thing by what it really is" and creating a universal language that can be utilized for any purpose. CLOC does NOT include Bias like quantity, cost, etc. These things are used in conjunction with the code to do any kind of analysis needed.2016Methods & Models
Achieving Affordability through high fidelity ROM cost estimatesEric BullerAchieving affordability can be challenging especially if early decisions are made without proper cost estimates. Developing high fidelity ROM cost estimates and identifying capability tradeoffs during the requirements generation phase can be critical to the success of achieving long term affordability. We intend to demonstrate through analysis that preforming high fidelity ROM cost estimates with capability tradeoffs allow decisions makers to informed choices on mission requirements that achieve affordability for future programs.2016Methods & Models
A Regression Method for Sparsely-Populated DatasetsDaniel BarkmeyerA method is presented for including sparsely-populated independent variables in a regression analysis without introducing subjectivity or statistical bias. The method is shown to reproduce the result of a traditional regression method for a fully populated dataset, and to converges to the same result on a sparsely-populated dataset as that dataset decreases in sparseness. Application of the method to develop a new, empirically-derived model for spacecraft testing schedule duration will also be presented.2016Parametrics
Improvement Curves: An Early Production MethodologyBrent JohnstoneLearning slope selection is a critical parameter in manufacturing labor estimates. Incorrect ex ante predictions lead to over- or understatements of projected hours. Existing literature provides little guidance on ex ante selection, particularly when some actual cost data exists but the program is well short of maturity. A methodology is offered using engineered labor standards and legacy performance to establish a basic learning curve slope to which early performance asymptotically recovers over time.2016Parametrics
The NRO CER Analysis ToolDonald MacKenzieThe NRO Cost and Acquisition Assessment Group (CAAG) uses its CER Analysis Tool, CERAT, to inform CER development. CERAT analyzes CERs for sensitivity to influential data points (IDPs). The impacts on estimated costs for a target data point when data points are removed are the primary outputs. The changes in recorded CER constants when data points are removed also help in assessing overall CER "stability." CERAT also provides several other aids to CER developers.2016Parametrics
A Parameter Driven WorldJeffrey PlattenParametric estimating is gaining acceptance. DFARS requires DOD contractors to maintain an estimating system. Parameters are the characteristics, features, or measurable factors that define a product or program. What makes a good parameter? What are the pros and cons of parametric cost estimating? How do you develop and maintain a parametric estimating database/model? What does the future hold, beyond just estimating? How do you gain parametric control over touch labor, support labor, and parts costs to improve affordability?2016Parametrics
Generating a Semi-Automated "Similar To" Basis Of Estimate from a Complex Parametric Hardware Cost Model for AntennasDanny Polidi, David BloomThis paper discusses the development of a "Similar-To" Basis Of Estimate (BOE) generation tool used in conjunction with a Complex Parametric Antenna Cost Model. Starting with the parametric model based on quantifiable sizing mechanisms which are designed to quickly and accurately calculate the "top-down" cost for all engineering and operations disciplines and functions required for antenna development and test, cost is generated, "similar to" programs are identified, and a BOE can be auto-populated.2016Parametrics
Analysis of Alternatives from a Cost Estimating PerspectiveKirby Hom, Kenny RaglandSubsequent to the Weapon Systems Acquisition Reform Act of 2009, there have been other significant DoD policy changes that require Service sponsors to conduct an Analysis of Alternatives (AoA) prior to Milestone A. "About three-quarters of a program's total life cycle cost is influenced by decisions made before it is approved to start development" [GAO-09-665]. From a cost estimating perspective, a successful AoA rests with the study approach, overall costing methodologies, key insights from trades analyses, and lessons learned.2016Government Processes

Testing Benford's Law with Software Code CountsChuck Knight, Chris KaldesWhen analyzing a data set, common thinking may lead one to suspect that the leading digit of each data point would follow a uniform distribution, where each digit (1 through 9) has an equal probability of occurrence. Benford's law, to the contrary, states that the first digit of each data point will conform to a nonuniform distribution. More specifically, it states that a data point is more likely to begin with a one than a two, a two more likely than a three, a three more likely than a four, and so on. ...2014Information Technology

Relating Cost to Performance: The Performance-Based Cost ModelMichael Jeffers, Robert Nehring, Jean-Ali Tavassoli, Kelly Meyers, Robert JonesFor decades, in order to produce a cost estimate, estimators have been heavily reliant on the technical characteristics of a system, such as weight for hardware elements or source lines of code (SLOC) for software elements, as specified by designers and engineers. Quite often, a question will arise about the cost of adding additional performance requirements to a system design (or in a design-to-cost scenario, the savings to be achieved by removing requirements). Traditionally, the engineers will then have to undertake a design cycle to determine how the shift in requirements will change the system. ...2014Information Technology

Linking Parametric Estimates to Program Management Artifacts (LPEPM)Mike Smith, Ted Mills, John SwarenA common fate of parametric cost and schedule estimates is that they fall into disuse as a Project's own artifacts (e.g. Work Breakdown Structure (WBS), budget, schedule, risk lists, etc.) are created and mature. Parametric estimates typically do not map cleanly to WBS or schedule-derived artifacts, allowing a sense among Project Managers (PMs) ? rightly or wrongly ? that "parametric estimates are fine, but they don't reflect my project." ...2014Parametrics

Cost and Data Issues facing Today’s Cybersecurity AnalystsBob HuntCybersecurity threats and counter measures are evolving at a rapid pace. Analysts need a solution for assessing a non-static situation. Many organizations are simply costing a proposed plan without a strategic or sustainment plan. Current studies imply that it is more costly to defend against a cybersecurity attack than to execute the attack. Studies also indicate that the typical security breach is not detected until about 200 days after the breach. Analysts need to understand the scope of cybersecurity. Is it physical, computer, hardware, people, policy, or all of the above?20202020 SCAF/ICEAA Virtual Conference
The Art of JudgementAndy NolanMany of us rely on “expert judgement” when estimating, but the evidence is that it can be unreliable. Based on a study of 3760 guesses, we noticed that 70% of people tend to underestimate. A new study in 2020 of 7400 guesses, showed that 69% of people tend to quote a narrow min-max range when guessing a 3-point estimate. When using judgement, most of us are too low and too precise, we are precisely wrong!20202020 SCAF/ICEAA Virtual Conference
The Quantitative Risk Management ImperativeChristian B. SmartRisk is an important consideration for all projects. However, as a society we are risk blind. When projects plan, they tend to look only at the best-case scenario. Risk is not just a nice to have, it is a critical ingredient in project success, and it needs to be analyzed quantitatively. The use of point estimates, averages, and qualitative methods all underestimate risk. The use of quantitative methods for risk analysis is well established. We discuss how to successfully implement them in the analysis of project risk.20202020 SCAF/ICEAA Virtual Conference

Review of Quantitative Methods for Designing Availability-Based ContractsAmir Reza Kashani Pour, Peter Sandborn, Qingbin CuiUnderstanding the total life-cycle cost is an essential part of all sustainment contracts. Sustainment constitutes 70% or more of the total life-cycle cost of safety-, mission-, and infrastructure-critical systems. For many types of systems, availability is the most critical factor in determining the total life-cycle cost of the system. To address this, availability-based contracts have been introduced in the governmental and non-governmental acquisitions space (e.g., energy, defense, transportation, and healthcare). 2016Journal of Cost Analysis and Parametrics
Tooth-to-Tail Impact Analysis: Combining Econometric Modeling and Bayesian Networks to Assess Support Cost Consequences Due to Changes in Force StructureBradley C. Boehmke, Alan W. Johnson, Edward D. White, Jeffery D. Weir, Mark A. GallagherCurrent constraints in the fiscal environment are forcing the Air Force, and its sister services, to assess force reduction considerations. With significant force reduction comes the need to model and assess the potential impact that these changes may have on support resources. Previous research has remained heavily focused on a ratio approach for linking the tooth and tail ends of the Air Force cost spectrum and, although recent research has augmented this literature stream by providing more statistical rigor behind tooth-to-tail relationships, an adequate decision support tool has yet to be explored to aid decision-makers. 2016Journal of Cost Analysis and Parametrics

Balancing Expert Opinion and Historical Data: The Case of Baseball UmpiresRicardo ValerdiMany decisions benefit from situations where there exist both ample expert opinion and historical data. In cost modeling these may include the costs of software development, the learning curve rates for specific manufacturing tasks, and the unit rate costs of operating certain products. When making forecasts we are often faced with the decision to base our estimates on either expert opinion or historical data. 2016Journal of Cost Analysis and Parametrics

To Cost an Elephant: An Exploratory Survey on Cost Estimating Practice in the Light of Product-Service-SystemsEttore Settanni, Nils E. Thenent, Linda B. Newnes, Glenn Parry, Yee Mey GohBusinesses now contracting for availability are regarded as part of a paradigm shift away from the familiar product and support business model. The main difference being that such businesses eventually commit to provide a service outcome via product-service-system. The research presented in this article investigates how current cost estimating practice relates with the idea of having as the point of focus for the analysis a product-service-system delivering service outcomes, rather than a product. 2015Journal of Cost Analysis and Parametrics
Parametric Scale-Up Cost Factors for Conventional and Micro-Scale ToolsDonald S. Remer, Kerry M. ChinThis article estimates cost scale-up factors for micro-scale tools, including high speed steel micro tools, micro thread hand taps, and various types of mesh and wires. Many of these tools initially have a positive scale-up factor where the material costs directly correlate with the cost of the tool; they then transition to a negative scale-up factor at the micro-scale where manufacturing is more difficult and becomes the determining factor for the prices of the products. 2015Journal of Cost Analysis and Parametrics

Applications of a Parsimonious Model of Development Programs Costs and SchedulesDavid Lee, Carol Dezwarte, Stephanie Sigalas-Markham, Jeremy EckhauseA model of the cost and schedule of a development program, characterized by three non-dimensional parameters, gives means for estimating the cost and schedule impacts of constraining funding below planned levels, as well as for assessing the realism of the costs and schedules of planned programs. In contrast to models of the Norden-Rayleigh-Weibull class, the model explicitly considers specific components of cost, and captures the distinction between a development programs value (i.e., the things delivered) and its cost (i.e., the money paid to acquire the value). 2014Journal of Cost Analysis and Parametrics

A Process for the Development and Evaluation of Preliminary Construction Material Quantity Estimation Models Using Backward Elimination Regression and Neural NetworksBorja Garci­a de Soto, Bryan T. Adey, Dilum FernandoDuring the early stages of a project, it is beneficial to have an accurate preliminary estimate of its cost. One way to make those estimates is by determining the amount of construction material quantities that are required and then multiplying the estimated construction material quantities by the corresponding unit cost. One advantage of making estimates in this way is that it allows for the segregation of quantities and costs. 2014Journal of Cost Analysis and Parametrics

Can DoD Inflation Indices and Discounting Processes Be Improved?Kathryn Connor, James DrydenCurrently the DoD is facing an uncertain budget environment. This will have an impact on what the DoD can spend for acquisition programs and sustainment of major weapons systems. Current practices for inflation and discounting skew program affordability, especially during operations and sustainment. In this presentation, we look at how well current inflation indices and discount rates serve programs today and whether there are strategies to improve the accuracy of these estimates. After examining the experience of several major weapons systems we have identified potential policy changes and strategies for cost estimators to employ on inflation and discounting. We believe that these can improve a program's understanding of long run affordability and potential risks associated with inflation and discounting.

The Forgotten Costs and Uncertainty Analysis within the DoD Acquisition EnvironmentRoberto Perez, Elizabeth EvansDespite the best efforts of the Department of Defense (DoD) to capture all costs associated with the life cycle of acquisition programs, it continues to be an elusive. A primary reason for this shortcoming in cost estimating is the lack of time spent on estimating operations & sustainment (O&S) costs compared to the time and effort estimating research, development, and procurement costs. The implications for this imbalance are significant given the fact that 60 - 70 percent of an acquisition program's life cycle cost is comprised of operations and support...2013Life Cycle Cost

Construction vs. Systems Acquisition Cost Estimating: A Comparative AnalysisTom Sanders, Steve Essig, Tim AndersonThe continued push to improve DOD's acquisition processes includes several thrusts-regulatory streamlining, improving use of incentives, and workforce optimization. These are not new. To deal with these concerns, the acquisition community has a unique opportunity. DOD Cost estimators have recently received a strong "vote of confidence" in the acquisition community; new positions have been created and existing positions have been protected. That is not necessarily so in the construction industry, another large employer of cost estimators. The construction industry has undergone a transformation over the past six years, beginning with the housing collapse in 2006 and enduring through the years of the Great Recession...2013Management
The Joint Integrated Analysis Tool (JIAT)- Making Data Sharing EasierNiatika Griffin, Melissa Cyrulik, John McGahanThe silver lining in the current DoD budget turmoil is that it provides us with an opportunity to reexamine how we operate and look for ways to be more efficient. In times of belt tightening, improving access and distribution of established resources is imperative. We are challenged to ultimately improve how we share cost resources. For cost professionals, these resources include databases of cost and technical information, libraries of resources, and approved models that can be used rather than re-invented.

Net Present Value (NPV): The Basics and the PitfallsKevin Schutt, Nathan Honsowetz One of the essential metrics of an economic analysis is the Net Present Value (NPV) measure. While it is a fairly simple calculation, made even more routine and efficient by modern technology, be wary of pitfalls in its application. This presentation will cover the basic components and methodology of NPV and discuss the pitfalls and easily-made mistakes in its application. These include incorrect discount rate formulas, inconsistent treatment of inflation, incorrect understanding of the discount rate, incorrect application of Excel's "=NPV()" formula (hint: it's not really "Net"!), and including irrelevant cash flows. Come learn about Net Present Value and avoid these potentially career-limiting mistakes!2013Management
Fifteen Undeniable Truths About Project Cost Estimates, or Why You Need an Independent Cost EstimateTim AndersonAll project cost estimates are wrong, some more so than others. It is exceedingly difficult to accurately estimate the cost of a large project (e.g., major defense acquisition project). Reasons for this are manifold, but the primary causes seem to be general uncertainty, insufficient technical detail, unanticipated design/technical changes, funding and schedule perturbations over the acquisition life cycle, other programmatic "difficulties," and otherwise attempting to predict the future with imperfect information. The end result is that project cost estimates tend to be too low, with early estimates being the most likely to be understated...2013Management

Supplier Cost/Price AnalysesDavid Eck, Todd BishopUnder United States Federal Government contracts, an important but overlooked aspect is the audit and evaluation of a subcontractor's cost proposal. Requirements in the Federal Acquisition Regulations (FAR) provide for certain visibility into subcontractor's cost proposal depending on the value of the proposal. Additionally it is critical to note the FAR puts the onus of subcontractor cost (or price) analysis on the prime contractor. The expectation is that the same level of detail that the prime includes in its proposal should be included as support to a subcontractor's cost proposal. Effectively the prime must perform subcontractor cost analysis in accordance with the FAR...2013Management

Building an Analysis Schedule ‚“ Lessons Learned from the SGSS ProgramMatt Blocker, David JacinthoConstructing an integrated cost and schedule uncertainty model involves bringing together important program elements: cost, risk, and schedule. The model's core is the schedule; the linking of costs and risks to the schedule is what allows the implementation of time-dependent costs and, ultimately, an analysis that jointly considers cost and schedule. It follows, then, that one of the first, and often largest, difficulties in constructing an integrated cost and schedule model is the development of the schedule backbone...2013Methods and Models I

Since Operation Iraqi Freedom (OIF) began in 2003, military organizations have been able to request and receive immediate Overseas Contingency Operations (OCO) funding without following traditional procurement processes. This readily available funding has led to the emphasis of developing and maintaining operational capability in lieu of program estimates and resource management.

Estimating Alternatives for Joint Future Theater Lift (JFTL)Robert GeorgiUS military operations in Afghanistan and Iraq are making military transport aircraft work at rates not foreseen just a decade ago. At the same time the existing inventory of transport aircraft are limited in their ability to transport heavy cargo to austere unimproved landing zones where military forces routinely operate. The US Air Force (USAF) with considerable support from the US Army conducted the Joint Future Theater Lift (JFTL) Technology Study (JTS) to consider how best to equip its theater lift fleets beyond 2020 to address this need. The JTS was established by merging the US Army's Joint Heavy Lift (JHL) and the USAF's Advanced Joint Air Combat Systems (AJACS). The JTS analyzes the cost, risks, and operational effectiveness of theater lift technology alternatives that address capability shortfalls identified in the JFTL Initial Capabilities Document (ICD); an essential capability shortfall being the delivery of a combat-configured medium weight armored vehicle (up to 36 tons) into austere, short, unimproved landing areas without ground handling equipment.

Improving Cost Estimates in a Medical Acquisition EnvironmentMark Russo, Kimberly WallaceEstimating costs for drug development has proven difficult over the years. Difficulties stem from the overlapping of the Department of Defense (DoD) acquisition process and the Food and Drug Administration's (FDA's) review process, small data pool, industry close hold of cost data, the inherent difficulties in the drug development process, and the lack of using best practices in cost estimating. Over the past couple of years the medical cost community has been working towards improving their cost estimates. These efforts included the establishment of a standard drug development work breakdown structure to ensure that data could be collected and compared in a standard way. A medical cost model was then created in order to use the available data to develop program estimates...2013Methods and Models II
Incorporation of Program Priorities in Funding-Constrained EnvironmentsLeon Halstead, Michael Land, Derrick Kuhn, Bryan ShraderThe recent era of declining Federal (and organizational) budgets has given new impetus to the ability to prioritize funding in an efficient and effective manner. While there are multiple methodologies to pursue these budget reductions, there is a tendency for both allocations and reductions of funding to be top-down, i.e. Organization-driven with a less defensible framework to support Program priorities. This approach heightens the risk that Program goals and objectives will be negatively impacted due to underfunding in this manner due to lessened consideration of Program-specific environmental factors...2013Methods and Models II
Quantifying Uncertainty in Early Lifecycle Cost Estimation (QUELCE)Robert Stoddard, Robert Ferguson, Dennis Goldenson, Jim McCurley, Dave ZubrowEarly lifecycle cost estimation continues to grow in importance within both industry and the U.S. Government. In the commercial arena, shrinking business and product development cycles demand more rapid and early cost estimates. Within the U.S. Defense Department, cost estimates are now mandated prior to Milestone A approval within the DoD Acquisition Lifecycle. One of the primary challenges with early lifecycle cost estimation remains the incongruence of input data required by existing cost estimation models and the data available early in the lifecycle. Recent research into capability-based cost estimation offers improvements but ignores much of what may be viewed as program execution change drivers. These program execution change drivers embody the root causes of changes in program performance leading to changes in the cost of the program. As a result, our team developed the QUELCE method as an innovative approach to elicit domain expert knowledge about the possible future scenarios of change driver behavior for a given program...2013Methods and Models II
Sensitivity Analysis in Cost-Benefits AnalysisSteven IkelerThe Army has been using Cost-Benefits Analysis (C-BA) for all new requirements with cost impact for two years. As with the Analysis of Alternatives (AoA), a sensitivity analysis of the C-BA results is required. The C-BAs frequently use weighted decision matrices to combine the benefits into a single Cost-Benefit Index. This greatly simplifies the sensitivity analysis and facilitates allocation of cost to the individual benefits. The author reviewed the sensitivity analysis in 80 C-BAs. This session will address some of the techniques for presenting sensitivity analysis, the basic math behind the sensitivity analysis and allocating cost to benefits and generalizing the results to more complicated problems.2013Methods and Models II
Probabilistic Technology Investment Ranking SystemPeter FredericThis paper describes the Probabilistic Technology Investment Ranking System (PTIRS), a multi-tool cost estimating system. PTIRS is a new cost estimating tool that has been developed for the NASA Environmentally Responsible Aviation (ERA) Project at Langley Research Center. The ERA Project is charged with developing new technologies for commercial transport aircraft that will reduce fuel consumption, emissions, and noise. The PTIRS tool assesses the integrated, end-to-end benefits of a new technology and allows the benefits to be weighed against the cost of maturing, certifying, and ultimately implementing the technology in a generation-after-next (N+2) subsonic transport system. The tool is both deterministic and probabilistic: it allows inputs with ranges of uncertainty described as statistical distributions and it uses Monte Carlo simulation to produce results with statistically described ranges of uncertainty. The tool produces a two part answer: 1) the life cycle cost impact and noise, emission, and performance benefit of implementing and operating the new technology, and 2) the cost and time required to mature and certify the technology to a readiness level appropriate for full-scale development...2013Methods and Models II
Rapid Generation and Optimisation of Ship Compartment Configuration based on Life Cycle Cost and Operational EffectivenessAidan Depetro, Rhyan HoeyIt has been well established that the majority of Life Cycle Cost (LCC) is incurred during the in-service period. Among other factors, this is strongly linked to the design of the ship and the decisions made during the early design phase. In particular, compartment configuration can have a significant effect on LCC. Poorly considered compartment configuration and hull selection can result in hydrodynamic efficiencies which significantly increase energy consumption and hence fuel costs. Associated space limitations, inadequate or non-existent removal routes and other accessibility problems may result in expensive equipment overhaul and replacement procedures, invasive removal methods, longer maintenance availabilities and increased maintenance costs. Current design methods and decision analysis techniques focus mainly on the trade-off between operational effectiveness and acquisition cost rather than LCC...2013Methods and Models II
Data-Driven Estimating - Quantifying Electronics Complexity Using Public DataF. Gurney ThompsonThe parametric cost estimation industry is being challenged to increase the defendability of their estimates, mainly through comparison to analogous data. However, companies are more protective than ever of their high quality cost data. While this data is often obtainable, it usually comes with strings attached (non-disclosure agreements, etc.) that preclude its usage in defending your estimate. At the same time, government and military databases with cost and technical data are being exposed to the public, and while the noise introduced by granularity issues and the mapping process of this data presents its own set of challenges, this trend also contains the key to a solution...2013Methods and Models II
Affordability Analysis: The Role of Process, Cost and ROI Modeling In Improved Program PerformanceDan GalorathAffordability analysis as part of decision making may be the biggest edge of the decade for both commercial organizations and DoD / government organizations. Affordability has been addressed in the past but never to the level it is today. In an IT context companies struggle to increase profits and often view IT as a necessary evil: one that consumes resources rather than contributes to the bottom line. However, IT can be a significant contributor when IT decisions are made after modeling affordability in multiple dimensions.2013Methods and Models II
Applying Cost Analysis to the DoDAFMichael ButterworthCost analysts in the aerospace community today are being challenged to accurately estimate new and on-going program efforts that will be integrated into the Department of Defense Architecture Framework (DoDAF). The DoDAF provides a foundational framework for developing and representing architecture descriptions that ensure a common denominator for understanding, comparing, and integrating architectures across organizational, Joint, and multinational boundaries. It establishes data element definitions, rules, and relationships and a baseline set of products for consistent development of systems, integrated, or federated architectures...2013Methods and Models II
The Role of Value Engineering In Affordability AnalysisQuentin Redman, Robert Koury, Joseph Bobinis, Paul Tuttle, Kevin Woodward, Hein B.A. de JongThe purpose of this white paper is to describe the role Value Engineering plays within the affordability process. The paper is not a step by step "How To Conduct or Execute" Value Engineering (VE) but is a discussion of the context, input, setup, execution hints, and output of Value Engineering in support of conducting affordability analysis and management. As such it is important to understand the concept of affordability within the Systems Engineering paradigm. This paper is designed to provide insights, lessons learned, and suggestions for using Value Engineering in the affordability process...2013Methods and Models II
Adding Process Tailoring to Product Size for Better Cost EstimationDavid Bloom, Chris FudgeGenerally, when one is looking to create a parametric model to predict costs of an activity, then one looks to size relationships associated with that activity. For example, if one were to develop a parametric model for estimating the development of a Field Programmable Gate Array (FPGA), then, because most of the work to complete an FPGA revolves around software code development, building a parametric model around new code, modified code and reused code (with other size relationships) would probably be a good place to start...2013Parametrics
Evaluating Cost Relationships with Nonparametric StatisticsCaleb FlemingParametric statistics are often used to analyze data, evaluate hypotheses, and determine the significance of a given set of inputs. Most commonly, cost estimators use the following parametric testing measures for significance: Pearson's product-moment correlation, z-tests, t-tests, and Analysis of Variance (ANOVA) tests. While each of these tests is subjectively appropriate to evaluate varying scenarios, each test also objectively depends on the validity of a fixed set of assumptions. Though the assumptions differ by test, all root themselves in the general idea that the data is contained within an adequately large sample and follows a particular probability distribution with estimable parameters...2013Parametrics
Fit, Rather Than Assume, a CER Error DistributionShu-Ping HuAnalysts usually assume a distribution (e.g., normal, log-normal, or triangular) to model the errors of a cost estimating relationship (CER) for cost uncertainly analysis.

A distribution fitting tool is often used to hypothesize an appropriate distribution for a given set of data. It can also be applied to fit a distribution to...2013Parametrics
Developing a Military Aircraft Cost Estimating Model in KoreaSung Jin Kang, Dong Kyu KimA parametric cost estimating model is very useful for the weapon acquisition process.

Improving Program Affordability Through The Application of Data AnalyticsDavid Wang, Austin LeeIn the current budgetary environment, program affordability is a key concern. Improving program execution and minimizing schedule delays and cost growth are keys to improving program affordability. However, there is a lack of quantitative analysis of schedule risks, and a lack of understanding of the root causes for schedule delays and cost growth. Consequently, most of the common affordability improvement suggestions centered on relaxation of test and verification requirements, and streamlining of engineering processes may not address the true root causes. The effectiveness of these affordability improvement suggestions is uncertain...2013Parametrics

Probabilistic Mass Growth UncertaintiesDarren Elliott, Eric PlumerMass has been widely used as a variable input parameter for Cost Estimating Relationships (CER) for space systems. As these space systems progress from early concept studies and drawing boards to the launch pad, their masses tend to grow substantially hence adversely affecting a primary input to most modeling CERs. Modeling and predicting mass uncertainty, based on historical and analogous data, is therefore critical and is an integral part of modeling cost risk. This paper presents the results of an ongoing NASA effort to publish mass growth datasheet for adjusting single-point Technical Baseline Estimates (TBE) of masses of space instruments as well as spacecraft, for both earth orbiting and deep space missions at various stages of a project's lifecycle...2013Risk I

Top-level Schedule Distribution ModelsPeter FredericIn the initial stages of a development project, it is sometimes necessary to build a summary-level schedule for planning and budgeting purposes before the day-by-day details of the project are fully defined or understood. However, when uncertainty assessments are performed on schedule networks containing few activities, the distribution forms chosen for individual activity durations can have a significant impact on the overall results. It is therefore important to choose uncertainty distribution forms that accurately represent the behavior of the sub-network of activities represented by each summary activity...2013Risk I

Cost of Mission Assurance for Space ProgramsErik Burgess, Joe Frisbie, Michelle Jones, Chad KrauseStandards and strategies for assuring successful space missions have evolved in recent years, with some programs moving toward traditional government standards and others moving to industry's commercial standards. This has prompted questions from several government leaders about the cost of mission assurance. Although there are decades of engineering studies, test data, and on-orbit failure data to support detailed evaluation of the technical merits of various approaches, there is very little on the cost side of the equation. The National Reconnaissance Office Cost Analysis Improvement Group (NRO CAIG) has begun to address this by focusing on two of the more costly areas of mission assurance-environmental testing and high-reliability electronic parts...2013Risk I

Methods to Analyze Services Portfolio Cost Drivers and EfficienciesValerie Reinert, Virginia WydlerThis presentation provides a statistical methodology used to evaluate the "health" of a services portfolio through performance data analysis and cost analysis, with the goal to identify cost drivers and efficiencies for performance improvement. Managing a Federal government portfolio is a complex endeavor. Portfolio Managers have a major responsibility to evaluate whether their portfolio is operating efficiently and effectively. Thus, they need to use analytical procedures that, when executed, will evaluate the "health" of the portfolio and identify areas for increased efficiency and effectiveness. If the analysis is not data-driven, this leads to a lack of proper business case analysis and cost benefit analysis to weed out bad actors in the portfolio...2013eTrack

Robust Default Correlation for Cost Risk AnalysisChristian SmartCorrelation is an important consideration in cost risk analysis. Exclusion of correlation from cost risk analysis results in the de facto assumption that all risks are independent. The assumption of independence leads to significant underestimation of total risk.

For instance, it is difficult to estimate the exact correlation value between the structures and thermal protection subsystems in a cost risk estimate...2013Risk II
Use of the Risk Driver Method in Monte Carlo Simulation of a Project ScheduleDavid HulettIdentifying the root causes of project schedule and cost risk requires that the risk to the project schedule is clearly and directly driven by identified and quantified risks. In the Risk Driver Method the risks from the Risk Register drive the simulation. (As a side note, we find that the Risk Registers are not complete-during the interviews to collect risk data the interviewees introduce important risks that are, surprisingly, missing from the Risk Register.) The Risk Driver Method differs from older, more traditional approaches in which 3-point (low, most likely and high) estimates of the activity durations are applied directly to activity durations...2013Risk II
Base Realignment and Closure (BRAC) Savings and Acquisition RiskPeter Braxton, Kevin Cincotta, Richard LeeThe Government Accountability Office (GAO) recently released the study Military Base Realignments and Closures: Updated Costs and Savings Estimates from BRAC 2005 (GAO-12-709R, June 29, 2012). Its appendices contain a wealth of risk data, with initial estimates (2005 BRAC commission) and final costs (Fiscal year 2011 DOD budget) for 175 distinct BRAC initiatives. Applying an innovative method for modeling within-program risk and uncertainty using cross-program data, this paper derives cost growth factors (CGFs) and coefficients of variation (CVs) for BRAC initiatives. Furthermore, the pattern in these data is astoundingly similar to that found in major defense acquisition program (MDAP) data, a strong confirmation of this modeling approach (meta analysis)...2013Risk II

In the realm of cost estimation, contingency refers to a reserve above and beyond a baseline estimate that would be tapped if one or more unexpected events led to higher program costs. Ideally, the selection of a contingency amount should be based on achieving a particular level of confidence derived from cost uncertainty and risk analyses, but often a mere rule-of-thumb percentage (e.g. 15% of the baseline estimate) is applied...2013Risk II

Estimating Real-Time Software Projects with the COSMIC Functional Size Measurement Method and the ISBSG RepositoryH.S. van HeeringenNowadays, software project estimation of administrative software systems has evolved into quite a mature stage. Standardized functional size measurement methods, like IFPUG and NESMA, are used to measure the functionality that the software application is going to offer to the user and this functional size is considered to be the main cost driver for administrative software projects. These methods are suitable for project estimation, because they measure the functional user requirements (which should be described before the project starts), instead of the actual delivered product (for instance source lines of code, which can only be measured after the project finished)...2013Information Technology
The COSMIC Functional Size Measurement Method: An IntroductionH.S. van HeeringenThe COSMIC functional size measurement method is a relatively new and not very well known method to measure the functional size of pieces of software. The main advantages of this method over the existing methods (like IFPUG and NESMA function point analysis) is that COSMIC is designed to also measure other types of software than the traditional administrative software. COSMIC can therefore be used to measure real-time, embedded, infrastructure software, as well as administrative software. Another advantage is the continuous scale that is used in the COSMIC method, which makes it possible to accurately measure the difference in size between different functional processes...2013Information Technology

While "Agile" software development is geared towards producing usable software products more rapidly than traditional waterfall or incremental methods, it also requires more flexibility with managing requirements. The main challenge this has created for program managers is figuring out how to effectively manage scope, cost, schedule, and performance in this flexible, fast-paced development environment in which requirements are more fluid. In turn, cost estimators have been challenged to develop new data collection approaches and estimating methodologies to more effectively estimate software costs for these "Agile" programs...2013Information Technology

Correlation Matrices RevisitedSteven IkelerIn a cost risk analysis, risk distributions are sometimes assigned at a low level and then combined, most commonly using Monte Carlo simulation. When using this technique, it is important to use a realistic correlation matrix. It is usually impractical to know all the pairwise correlations. This session will address some of the techniques for completing a credible correlation matrix at differing levels of input information and certainty. Additionally, the session will show examples and review the mathematics behind legitimate correlation matrices. Past sessions have discussed these topics and typically deal with correction techniques for expert-based correlation matrices. This session will be different since it deals less with correcting expert based correlation matrices and more with dealing with uncertainty in the correlations or incomplete correlation matrices. It will also address an extension of the problem to a parametric analysis problem.2013Risk II
New Air Force Integrated Baseline Review (IBR) Process - A Quick Reaction Capability (QRC) PerspectiveJames Ross, Martin Levitan, Christine Bolton, Barbara MeyersSince the early 1990s, the U.S. Air Force has been using Integrated Baseline Reviews (IBR) as a key technique for early assessment of the efficiency and effectiveness of baseline plans, resource allocations, scheduling and costs. Much of the earlier IBR doctrine does an excellent job describing what is required to complete these assessments, but little detail had been written about the specific processes, procedures, steps and techniques required to undertake these assessments. The January 2012 "Air Force Integrated Baseline Review (IBR) Process Guide", developed by SAF/AQXC personnel, is one of the best documents to date to address this concern.

Estimating Cost To-Go Without Stable EVM DataPeter Frederic, Ronald K. LarsonInitial independent estimates for development programs are typically created using parametric methods. As a program progresses, it becomes important to separate sunk cost from cost to-go. In the very early stages of a program, it is acceptable to estimate cost to-go by simply subtracting the reported sunk cost from the parametrically-estimated total cost. However, as the program continues to progress and more significant progress accumulates, we can no longer assume that dollars spent equate directly to technical progress. It is then necessary to understand progress to-date in order to estimate cost to-go...2013Earned Value Management

Ideally, analysts develop the cost improvement curve by analyzing unit cost data. However, it is common that instead of unit costs, analysts must develop the cost improvement curve from lot cost data. An essential step in this process is to estimate the theoretical lot midpoints for each lot, to proceed with the curve-fitting process.2013Journal of Cost Analysis and Parametrics
A Macro-Stochastic Model for Improving the Accuracy of Department of Defense Life Cycle Cost EstimatesErin Ryan, Christine Schubert Kabban, David Jacques, Jonathan D. RitschelThe authors present a prognostic cost model that is shown to provide significantly more accurate estimates of life cycle costs for Department of Defense programs. Unlike current cost estimation approaches, this model does not rely on the assumption of a fixed program baseline. Instead, the model presented here adopts a stochastic approach to program uncertainty, seeking to identify and incorporate top-level (i.e., macro) drivers of estimating error to produce a cost estimate that is likely to be more accurate in the real world of shifting program baselines. 2013Journal of Cost Analysis and Parametrics
Comparison between the Mix-Based Costing and the Activity-Based Costing Methods in the Costing of Construction ProjectsLeandro Torres Di Gregorio, Carlos Alberto Pereira SoaresAfter bibliographic research on costing methods in civil construction, and a presentation of the mix-based costing method, as well as an application of the activity-based costing method in the costing of civil construction projects based on other authors, a possible application of the mix-based costing was sought. This method allows the distribution of costs and indirect expenses to products without the subjectivities and uncertainties typical of traditional apportionment, by means of analyses of different production scenarios.2013Journal of Cost Analysis and Parametrics

Introducing Reliability and Availability Requirements into TOC ModelsEvin J. Stump, Wendy W. LeeTwo important system requirements are reliability and availability. Reliability is the probability of no disabling failures over a certain span of time, while availability is the ratio of the time the system will actually fulfill its operational expectations, to the total time it is expected to fulfill them. Both of these are often included in system specifications...2012Parametrics
Using Method of Moments in Schedule Risk AnalysisRaymond P. CovertA program schedule is a critical tool of program management. Program schedules based on discrete estimates of time lack the necessary information to provide a robust determination of schedule uncertainty and therefore the risk that the proposed schedule will be completed on time. To determine the risk that a proposed, discrete schedule will meet a particular schedule and to find the probable critical paths (i.e., the criticality index), a probabilistic schedule risk analysis (SRA) is performed. SRA is a process by which probability density functions (PDFs), usually triangular, are defined at the task level in an effort to quantify the uncertainty of each task element...2012Risk

A Holistic Approach to Multiyear ProcurementsAnn Hawpe, Travis WinsteadMulti-year contracts have the potential to save the Government a substantial amount of money if they are executed on stable programs in an environment with stable requirements and funding. With the current economic pressure for defense programs to do more with less, multi-year contracts are a good option for programs that meet these criteria. The largest amount of savings is the result of procuring a larger quantity of parts than would be procured with a year-over-year contract structure, thus realizing economies of scale. Savings are also captured when the labor hours to develop and submit year-over-year proposals are factored into the calculations...2012Management

Using the Tools of Persuasion to "Sell" Your EstimateJennifer KirchhofferWhat is the difference between a good cost estimator and a great cost estimator? Both have robust estimating skills and knowledge, but only great cost estimators are able to garner acceptance and usage of their estimates from even their harshest critics. The ability to "sell" the estimate is key to the utilization of the estimate in the proper context by the decision makers. Our jobs often entail delivering news that our customers and leaders are not anxious to hear. Many factors work against us as we try to garner support and acceptance of the estimates...2012Management

Modeling R&D Budget ProfilesErik BurgessPrior research sponsored by the National Reconnaissance Office (NRO) and published in the Journal of Parametrics (Summer 2006) has become the principal method for developing space and ground segment budget profiles for NRO programs. Since then, the practice of budgeting to independent cost estimates has been signed into law for the intelligence community. The resulting scrutiny and reliance on budget-phasing models has motivated several improvements that should be relevant to the estimating process for other DoD commodities. The presentation first reviews the mathematical formulation of expenditure profiles that are based on historical data, and how some of the resulting accuracy metrics have been useful in defending annual budgets. New models for space and ground systems are presented. Since the annual budget authority required to support an expenditure stream is heavily dependent on a program's execution rates (i.e., outlay rates), we also present a new approach for estimating what those outlay rates will be. This is a new area of responsibility for most cost estimating organizations, yet its impact on annual budget requests can be significant.2012Management

Discrepancy Report Prioritization and Software Maintenance ImpactsJennifer Woolley, Kyle ThomasIn the current budget-constrained environment, programs and organizations throughout the Intelligence Community (IC) are searching for new strategies to reduce costs. Rather than sacrificing new capabilities, maintenance is often one of the first areas of reduction. Many organizations perform developed software maintenance based on the submission of Discrepancy Reports (DRs), which are ranked according to their level of severity/importance. One approach to cutting maintenance costs involves only focusing on higher levels of DRs while leaving lower level DRs postponed or unaddressed. This strategy allows for a reduction in personnel because fewer DRs must be completed...2012Life Cycle Cost

Optimization of Cost and Performance in Complex Systems Using System Dynamics ModelingMichael Polly, Benjamin HarrisAnalysis of trade spaces between cost and performance is critical to win new contract pursuits in today's highly competitive environment. The overall goal in a program is to design and produce a system that maximizes both performance and affordability. In attempting to balance cost and performance, traditional cost models only allow for experimentation with one variable at a time. This can be very cumbersome on large systems, and inhibits how much of the trade space can be explored under time constraints. Altering one variable at a time also limits the number of cost estimating relationships that can be incorporated into the analysis...2012Earned Value Management Track

EVM for the Rest of UsJavier SloninskyEarned Value Management (EVM) is the practice of evaluating cost and schedule data to measure productivity and progress throughout the lifecyle of a project. EVM, however, often has the stigma of being overly complex and burdensome to implement in a useful way. This session will discuss best practices in implementing a simple yet robust earned value management solution for organizations that benefit from progress measurement and the ability to forecast cost performance, but don't need to comply with ANSI 748, the EVM standard often used by government agencies and contractors. We'll discuss topics including the integration of required data, developing key performance indicators (KPI) and metrics, application of rules of credit, updating of percent complete, and automated EV reporting.2012Earned Value Management Track
A New EVM Performance Index: The MRPIMichael NosbischIt has long been understood that the accuracy of the cost performance index (CPI) is closely tied to how management reserve (MR) has been historically utilized on a specific project/program. However, a formal assessment of MR usage is still not consistently performed in conjunction with CPI calculation and subsequent analysis. This presentation will offer a potential solution to this issue, by proposing a "Management Reserve Performance Index," or "MRPI." Once calculated, the author will demonstrate how the MRPI can be then used to develop a "risk-adjusted IEAC" that provides a more accurate assessment of a project's or program's overall cost performance.2012Earned Value Management Track

SLOC is by no means the only way to measure the size of a project but it is the most mature measure and is well understood by decision makers. Software cost estimating that relies on SLOC as an input depends on accurate and consistent counts. The problem is that no standard has been universally accepted for defining SLOC. Numerous code counting tools in use throughout the industry rely on interpretations of the definition of a line of code...2012Software/Hardware
COTS Estimating Metrics for Increased Cost AccuracyJoshua Patapow, Eric TiminskiObserved cost analysis issue was that multiple Commercial Off-The-Shelf (COTS) Hardware/Software cost estimates were significantly higher than recent contract award values. Using data from those contract awards, an analytical approach and metrics were developed to ensure increased accuracy on future estimates. For COTS Hardware (HW) and Software (SW), a metric of the actual contract price as a percentage of the mean online price/list price (Part I) was developed. Additionally, an estimating relationship was developed (Part II) to calculate the cost of annual maintenance support as a percentage of the actual HW/SW initial cost and the annual maintenance support actual contract price as a percentage of a vendor quote...2012Software/Hardware
Estimation of Expedited Systems Engineering SchedulesBarry Boehm, Dan Ingold, JoAnn LaneA major objective of many organizations is to reduce the calendar time needed for a project to perform its systems engineering (SE) functions, without compromising the resulting product's needed functionality and quality attributes. This paper will present the derivation of a model to estimate the necessary calendar time to perform the project's SE functions as a function of its product drivers (size, domain familiarity), process drivers (maturity, streamlining), project drivers (team cohesion, collaboration technology support), people drivers (knowledge, skills, and agility), and risk drivers (vs. relative needs for speed, quality, and scalability)...2012Software/Hardware

Joining Effort and Duration in a Probabilistic Method for Predicting Software Cost and ScheduleMichael A. RossThis paper describes a data-driven method for estimating the cost and schedule of software development projects. This method correlates the estimates of cost and schedule such that constraining (perhaps reducing) the cost will impact the estimated schedule and constraining (perhaps compressing) the schedule will impact the estimated cost. This method provides these estimates of cost and schedule that are probabilistic (i.e., provide a range of possible outcomes with associated probabilities of attainment); a capability that is essential to analyzing the impact that affordability and budget constraints have on program cost and schedule and their associated risks...2012Risk
Is My Schedule Ready for Risk Analysis?Mario FountanoThe ultimate goal of schedule risk analysis is the ability to provide project stakeholders with a risk mitigation plan that allows the team to make informed decisions concerning future cost and schedule performance. However, in order to perform schedule risk analysis, a project schedule must first be valid, and provide a clear path to project completion. This study presents the steps our team takes in order to evaluate the readiness of project schedules prior to integrating a risk analysis. Often, project schedules contain flaws in duration and logic, are left un-statused, or were never developed to capture the true nature of project work. The assessment process our team follows helps to build more confidence and transparency into project work. 2012Risk
Utilizing Optimization Technique to Enhance Cost and Schedule Risk AnalysisColin Smith, Brandon HerzogAdvancements in Monte Carlo simulations have enabled cost and schedule uncertainty analysis to be conducted on large, complex programs which could never be analyzed using conventional methods. Analysts are now able to predict with increasing confidence the budgetary requirements, schedule forecast, and risk mitigation measures on projects at all points during their lifecycle. These advancements in Monte Carlo technologies and methodologies have further lowered the barrier to entry for conducting uncertainty analysis; have reduced simulation times to mere fractions of a second; and have allowed for a comprehensive, integrated cost, schedule and risk analysis...2012Risk
The Unseen: Statistical Inference with Limited DataTrevor VanAttaObjective measurements of probability are often unavailable, and most significant choices under risk require an intuitive evaluation of probability.' -Nobel Laureates Daniel Kahneman and Amos Tversky. What are the odds of rolling a sum total of seven when tossing two dice? What is the probability of red turning up after a spin of a European roulette wheel? Most analysts, given a little time and a calculator, could answer these two questions with exact precision. For both of these questions, there is only one true correct answer. Such is the nature of probability analysis for questions that are decompositional (all possible outcomes can be determined), frequentistic (the experiment can be repeated an infinite number of times), and algorithmic (the results can be measured with numbers)...2012Risk
Applying the Pareto Principle to Distribution Assignment in Cost Risk and Uncertainty AnalysisJames R. Glenn, Christian Smart, Hetal Patel, Lawrence JohnsonSignificant effort and statistical knowledge is required in order to complete an accurate uncertainty analysis of a cost estimate. First, a representative sampling of data points must be collected in order to model appropriate distributions for each random variable in the estimate. Additionally, correlation between the random variables in the estimate must be properly assessed and applied. Finally, to generate the cumulative distribution of total costs (i.e., S-Curve) either the joint cumulative distribution function must be computed or an approximation technique such as Monte-Carlo simulation must be used...2012Risk
Inflation Cost Risk Analysis to Reduce Risks in BudgetingMichael DeCarlo, Eric DrukerFor any project there is a danger of unanticipated cost growth because inflation rates are extremely difficult to estimate. This presents a significant challenge to estimators. Predicting future inflation rates with some precision is possible, however, when the appropriate analysis is implemented. Even with previous recommendations from a major federal and commercial consulting firm, there is evidence indicating that the government has not been making adequate assessments of inflation rates for future budgeting. Without applying proper attention and techniques to the analysis and prediction of inflation rates, budgets run a higher than necessary risk for increased cost growth due to inflation prediction error...2012Risk
Diagnosing the Top Level Coefficient of Variation: An Alternative ApproachDaniel J. AndelinThe coefficient of variation (CV), defined as the standard deviation divided by the mean, is a useful metric to quantify the uncertainty inherent in a probability distribution, as it provides a relative (and thereby more intuitive) measure of spread than the variance or standard deviation. In the field of cost analysis, the CV can be used as a diagnostic to determine the level of risk and uncertainty built into an estimate and whether those levels fall within the expected range for a program of a given scope and complexity and at a given stage in its life-cycle...2012Risk
Real Data, Real UncertaintyAlfred Smith, Jeff McDowell, Lew Fichter, Wilson RosaCentral to any cost risk analysis and model are the uncertainty distributions assigned to point estimates. Ideally, the analyst will have a database of historical cost and technical information that can be used to objectively develop Cost Estimating Relationships (CERs) using approved statistical methods. From that analysis the analyst will be able to objectively define the shape and dispersion of the CER uncertainty distributions. Similarly, with a suitable database or expert opinions to draw upon, the analyst will be able to develop uncertainty distributions for the inputs to the CERs...2012Risk
Enhanced Scenario-Based Method for Cost Risk Analysis: Theory, Application, and ImplementationBryan Flynn, Peter Braxton, Paul Garvey, Richard LeeThere is a growing realization within the cost-analysis community that estimates of cumulative probability distributions of cost, or S-curves, too often understate true, underlying risk and uncertainty. Several organizations cite cases where return program acquisition costs, or actuals, fall at the 99th+ percentile on S-curves estimated years previously. This degree of deviation from the mean is a legitimate possibility for any one acquisition program. After all, there's no such thing as an "average" program. Variation is expected...2012Risk

In the case of the non-linear models it is neither appropriate nor accurate...2012Risk
Fitting Absolute Distributions to Limited DataBlake BoswellThe choice of probability distributions is a critical component for cost risk and uncertainty modeling. When data is available, distribution fitting techniques, such as Goodness of Fit (GoF) tests and Information Criteria (IC), can be applied to determine distributions that accurately describe potential cost realizations; however, with limited data GoF tests and IC based methods provide little or no insight into the best distribution choice. Therefore, when data is limited it is standard practice in cost risk and uncertainty modeling to solicit expert opinion in the construction of triangular distributions with vertices representing the best case, typical, and worst case scenarios...2012Risk

Accuracy Matters: Selecting a Lot-Based Cost Improvement CurveShu-Ping Hu, Alfred SmithThere are two commonly used cost improvement curve (CIC) theories: unit cost (UC) theory and cumulative average cost (CAC) theory. Ideally, analysts develop the CIC by analyzing unit cost data. However, it is common that instead of unit costs, analysts must develop the CIC from lot cost data. An essential step in this process is to estimate the theoretical lot midpoints (LMP) for each lot, to proceed with the curve-fitting process. LMP is generally associated with UC theory, where the midpoint is always within the lot. The more general lot plot point (LPP) term is used in the context of both the UC and CAC theories...2012Methods and Models I

Valuation in Cost Estimating: Taking a Page from the Investment Banker's PlaybookKevin SchuttValuation is "the process of estimating what something is worth". It is commonly undertaken in investment banking to support activities such as initial public offerings of company stock and mergers & acquisitions. The need for valuation analysis arose in a cost estimation setting in order to satisfy Office of Management and Budget budgetary treatment criteria, yet valuation techniques in general may be a useful addition to the cost estimator's toolkit, facilitating price analysis and cross-checks of cost estimates. Likewise, cost estimation techniques may inform valuation analysis. While cost estimation generally results in market-independent estimates, valuation provides the viewpoint of what the market will bear. This presentation will provide an overview of four major valuation techniques: Price multiple; Replacement cost; Comparable transaction, and Discounted Cash Flow. A case study in valuation will be presented. 2012Methods and Models II

Error Analysis of a Custom Cost ModelRaymond P. Covert, Donald L. Trapp, Noah WrightHow do you know how well a custom cost model performs? If it is based on historical data, then the simplest performance measurement is the model's percent standard error (PSE). The PSE measures a historically-derived model's ability to re-predict its underlying database. In this presentation we will demonstrate an analytic error analysis of a custom cost model using historically-derived cost estimating relationships (CERs) and factors. We will provide a sample model and show how we calculated the PSE of each of the CERs from the data as well as developing the error calculations for each step in the model. We will show how we used the concepts of effective correlation coefficients, propagation of errors, and the calculated variances of the sums and differences of two random variables.2012Parametrics

The Perils of Portability: CGFs and CVsPeter Braxton, Richard Coleman, Richard Lee, Brian Flynn, Megan Guild, Jack Smuck, Kevin CincottaWith the provisions of the Weapon Systems Acquisition Reform Act of 2009, or WSARA, raising the importance and visibility of risk analysis, it is an opportune time to revisit how risk benchmarks based on historical data are both derived and applied. This paper will focus on two key summary risk metrics: (1) the cost growth factor, or CGF, which captures historical cost growth for individual programs and is used collectively to capture the pervasive tendency to underestimate cost; and (2) the coefficient of variation, or CV, as a measure of the uncertainty in both historical and new estimates...2011Risk

Cost Risk Allocation Theory and PracticeChristian SmartRisk allocation is the assignment of risk reserves from a total project or portfolio level to individual constituent elements. For example, cost risk at the total project level is often allocated to individual work breakdown structure (WBS) elements. This is a non-trivial exercise in most instances because of issues related to the aggregation of risks, such as the fact that percentiles do not add. For example if a project is funded at a 70% confidence level then one cannot simply allocate that funding to WBS elements by assigning each its 70% confidence level estimate...2011Risk

Function Point Analysis: One Size Fits AllDan FrenchThere are many challenges when faced with creating estimates for software development projects. However, without a doubt the single largest driver for cost, effort and duration is project size.
The typical approach to sizing a software project, if it is tried at all, is to estimate software lines of code (SLOC). While this may be the most expeditious method, history has shown that this approach usually produces highly inaccurate estimates.
IBM developed function points as an alternative method to bring about more consistent and accurate project sizing for use in software project estimation. This methodology, while not a perfect solution, has enjoyed great success in more than 30 years of use world-wide...

Assessing Impact of Funding Constraints to Cost and ScheduleDarren Elliott, Antonio RippeCost risk and uncertainty over the past few years have drawn high interest in the cost estimation industry. Significant effort has been invested by the cost community to develop standard practices and refining tools to standardize how analysts to conduct risk and uncertainty analysis and examine the results. The most common output has been the cumulative distribution function (S-Curve) from which a target confidence level can be identified and a resulting cost target can be generated. This result is normally defined as the risk-adjusted estimate and phased over time to generate a desired funding level for the program...2011Models and Methods

Economic Elasticity of Tactical Missile CostsRaymond P. CovertEconomic elasticity is defined as the ratio of the percent change in one variable to the percent change in another variable. In missile production, it is hypothesized that two forms of elasticity dominate: price elasticity of demand and production cost improvement. The former implies prices and demand are inversely proportional, meaning if like goods (e.g., missiles) are cheaper, we tend to buy more of them. Production cost improvement is defined simply as the reduction of costs of successive units. Cost improvement curve theories, such as unit learning, explain the converse effect: If we can buy a greater quantity of an item, its relative cost decreases between successive units....2011Models and Methods

Costs of Achieving Software Technology ReadinessArlene MinkiewiczTechnology is advancing with lightning speed. Many of the complex systems required by the Department of Defense (DoD) and NASA require technological innovations to achieve sophisticated mission and state of the art accomplishments. Technology readiness assessments for complex systems and subsystems are important for both the government and its contractors to ensure proposed technologies meet program requirements. Without good technology assessments, programs may be funded that have little or no chance of success because success assumes use of technologies not yet confirmed to be realistic. The defense acquisition community recognizes this and has developed detailed guidelines for Technology Readiness Assessments (TRAs)...2010Software & IT
Software Cost Estimating RelationshipsJennifer LeottaSoftware cost overruns are a common problem for the majority of software development projects. With the ever increasing amount of software present in current Department of Defense (DOD) programs, it is extremely important to generate an accurate software cost estimates. There are many complex models that estimate software development productivity and costs. This paper builds upon the principles of these models to look for a simple regression model that can be used to generate accurate and defendable cost estimates for software development programs.2010Software & IT

Study on developing CERs with Insufficient Data in Korean R&D environmentSung Jin Kang, Yong Bok Lee, Dong Kyu KimParametric cost estimating models have been used widely to obtain appropriate cost estimates in the weapon acquisition process. A parametric cost estimating model is composed of some Cost Estimating Relationships(CERs). Generally, CERs are regression models which have been based on cost and technical data. In order to obtain a good cost estimate from CERs, it's important that gathering the sufficient historical data and selecting a proper method for statistical satisfaction under restricted condition is essential...2010Methods
Simple Mean, Weighted Mean, or Geometric Mean?Shu-Ping HuThere are three commonly used methods to calculate an average (i.e., mean): the simple average, weighted average, and geometric average. Analysts often use averages as estimating guidance when predicting nonrecurring (NR) costs using ratios of NR costs to first unit (T1) production costs. For example, when the average of the NR to T1 ratios is determined, the NR cost can be estimated as a factor of its T1 cost. Here, the simple average is simply the arithmetic mean of these ratios while the weighted average is derived by weighting each ratio by its T1 cost. Consequently, deciding which average (i.e., factor) is the most appropriate metric for estimating the nonrecurring cost is frequently debated...2010Methods
The Business Case for Bootstrapping: When You're Stuck with Incomplete Data, Here's How You Make it Work!Brett Gelso, Glenn Grossman, Eric DrukerThe purpose of inferential statistics is to reliably extend sample characteristics to a population. Mild assumptions such as the Central Limit Theorem and Identically and Independently Drawn (IID) estimators ensure that, based on a given level of precision, samples will be representative of the population from which it was drawn. However, when samples are small, most standard test statistics will be insignificant, because sample characteristics may fail to adequately capture variation in the population. Parametric Bootstrapping is an alternate approach which resamples the underlying distribution of the sample in order to estimate population characteristics. The objective of this presentation is to illustrate how to use Parametric Bootstrapping for Cost Estimating with small samples to enhance defensibility of cost estimates...2010Methods

Testing for the Significance of Cost Drivers Using Bootstrap SamplingDaniel FeldmanMost regression-based statistical modeling aims to derive, on the basis of historical data, an algebraic expression for estimating a quantity of interest, such as cost. Such an algebraic expression is characterized by one or more fit parameters, which are typically coefficients or exponents. Once these fit parameters are determined, it is a logical next step to test for their accuracy by a process called statistical inference. The fit parameters of a cost-estimating relationship (CER) are each directly linked to a candidate cost driver...2010Methods
Neural Network Cost Estimating RelationshipsEdwin DeanRegression, in various forms, is the tool of choice for parametric cost analysis (PCA). Neural networks are a largely unused analysis tool within the cost community. However, neural networks are an effective alternative to all forms of regression for PCA. This paper will illustrate the use of neural networks for PCA and will highlight similarities and differences with respect to the use of regression for PCA. For example, regression provides a linear or transformed linear approximation of parameters for a given set of data. Neural networks provide a purely nonlinear approximation of the parameters for the data...2010Methods

Time Phasing Cost Estimates in MS Excel ModelsWilliam Black, Matt Reiley, Jeffrey JaekleOne of the most critical, and often difficult, elements of developing a cost model is the determination of how to phase costs across the life of an estimate. Agency Cost Positions (ACPs) and Independent Cost Estimates (ICEs) are often conducted early in a program€ž¢s lifecycle, before detailed technical specifications, let alone schedules, have been developed. Even in those cases where a decent schedule does exist, issues still arise concerning the best way to translate technical and programmatic milestones into executable cost/budget profiles. This task proves even more daunting as external factors, such as the needs of other programs, are introduced into the estimating and budgeting process...2010Models

Estimating Life-cycle Cost of West Virginia Fiber Reinforced Polymer (FRP) Bridge DecksSidharta SahirmanThe main objective of the research was to study the economic viability of West Virginia Fiber Reinforced Polymer (FRP) bridge decks. Life?cycle cost of those bridge decks were estimated for conducting such analysis. Three main differences that distinguish the way the life?cycle cost of FRP deck was estimated are: (1) the manufacturing cost of a FRP bridge deck was estimated using learning curve theory; (2) cost savings in support structures when FRP is chosen as opposed to the alternative bridge deck was modeled; and (3) the service life was estimated based on factor method to minimize the subjectivity of the estimates. The three case studies for West Virginia FRP deck projects show that based on the estimated life?cycle cost, FRP decks are financially viable under certain conditions.2010Life Cycle Cost

DeMarcoMost organizations use a combination of commercial models, public models and proprietary CERS to develop confidence in their estimates. Homegrown CERs in the form of simple cost factors, equations, curves, and rules of thumb build confidence in estimates if they are derived from known, reliable data. However, most organizations have difficulty hosting, sharing and integrating their CERs with other estimating models. Homegrown CERs are commonly hosted in arcane Excel spreadsheets, and are not easily understood, audited or reused...2009Applications/Tools
True Cost Benefit Analysis FrameworkPeter PizzutilloThis paper introduces the innovations implemented in TruePlanning by PRICE Systems. Building on the success of the industry€ž¢s first true System of Systems Estimating Framework, PRICE Systems has enhanced this framework to include cost benefits analysis capabilities. Previously, organizations needed a collection of tools to create cost/benefit models; estimate system cost and benefits, and evaluate or rate the assessment of these alternatives. The paper shows how, in a single application, heterogeneous systems can be integrated, costs can be derived parametrically or bottoms up, benefits are estimated and payback and assessment criteria are evaluated...2009Applications/Tools

Estimating the Cost of a Depot Level Mobile Maintenance CapabilityAngela LemkeToday, the US Army is exploring options for an aviation sustainment level maintenance capability that can effectively cover initial drop in readiness. The Mobile Maintenance Capability concept provides key capabilities to sustain expeditionary Army aviation forces during operations in austere or immature theaters.

In order to support early program documentation and budgetary submission requirements, an initial life cycle cost estimate of a mobile maintenance capability was performed. Since, numerous alternatives have been proposed. This paper describes the assumptions, methodology, and results of the life cycle cost estimate for one of those options. The estimate was prepared using current Army guidance for an ACAT III program.

Contemporary Alternatives to Classical Risk Analysis ChallengesChris HutchingsRisks intrude on every aspect of our daily routines, whether it be through investing, playing a sport, weather forecasting, or just simple activities such as eating or driving; we are constantly in harms way.

In Project Management there are aspects of risk in several key areas, including the development of requirements, the rapid growth in technology and the instability of the operational environment, all of which ultimately adversely effect the three tangible measurements of effectiveness for any project, Performance, Schedule and Cost.

Incorporating Financial Sustainability Considerations into the Planning and Design of New Facilities in the National ParksFred Richardson, Matthew TetreaultThe backlog of maintenance in the National Park System is reaching crisis proportions. The total deferred maintenance (DM) backlog was estimated at $8 to $10 billion in 2008. This problem has worsened in recent years despite a concerted effort to combat it. The National Park Service (NPS) cannot hope to limit and reduce deferred maintenance without significant increases to its budgets for the Repair & Rehabilitation and Line Item Construction programs, which combined provide less than $100 million annually to address DM. Faced with this seemingly intractable problem, park planners should heed the maxim, First, do no harm. ...2009Management

The Challenge of Estimating Space System Costs‚Modeling the Relationship with Acquisition StrategyPaul S. KillingsworthIn recent years, a considerable number studies and blue-ribbon reports have highlighted the problems associated with the acquisition of military space systems. These problems are manifested by the fact that almost all major space programs under development by both the DoD and Intelligence Community have encountered (or are currently encountering) breaches of their cost, schedule, or technical baselines. The author hypothesizes that understanding the impact of a program cost estimate and its associated risk within the context of the complex program acquisition process may help us better understand the sources of cost growth...2009Management
Market Mapping for Production OptimizationDouglas K. HowarthThis paper describes methods for product optimization using market mapping. It is possible to optimize products by examining market conditions as over time and comparing them with evolving cost structures. Market mapping facilitates this analysis.
Products have important attributes associated with them, which includes their demand curves, prices and costs. Market demand maps reveal market boundaries and underserved price and quantity regions that producers can seek in order to improve product viability through reduced competition.

NASA Productivity StudyJoe Hamaker, Tom Coonce, Bob Bitten, Henry HertzfeldThis study was performed at the request of the NASA Administrator and examined NASA productivity in terms of economic efficiency. The analysis examined historical trends of NASA bang for the buck metrics over time, and compared NASA productivity to other organizations including the Air Force, the NRO, ESA and commercial space taking into the account the relative complexity of the missions. Past studies with a similar focus were reviewed and their results summarized. Finally, recommendations for improving NASA productivity were solicited from industry, government and academia and are documented in the study. The results of the study were briefed to the Administrator in late December 2008 and a journal quality paper is being prepared for submission to the Journal of Cost Analysis and Parametrics.2009Management

A Method for Estimating the Development and Production Cost of Advanced Radar Systems at the Subsystem and Component LevelDavid Stamm, Greg Bell, Paul GrimBudget constraints and high development and production costs have combined to limit the deployment of sensor systems needed for ballistic missile defense and other important military applications. To reduce the cost of new radar systems, designs must be based on reuse of components and subsystems. Similarly, in-service radars are being modified and upgraded to extend system performance and enhance supportability and sustainability. This shift in emphasis has created a need for a procedure to estimate radar modification costs and radar development and production programs where components and subsystems are reused in the early stages of the planning and budgeting cycle...2009Models
An Analytical Framework for Cost Estimating Relationship DevelopmentChristian Smart, George CulverCost estimating relationship (CER) development, particularly for spacecraft hardware, has traditionally been method-centric. Much attention has been paid to parameter calculation and goodness-of-fit statistics for particular methods. However, parametric modeling involves other critical factors that are often overlooked, including model validation. These factors are discussed, and a complete analytical framework for developing CERs is presented. Three popular methods for spacecraft hardware CER development are compared in the context of this framework, namely Minimum Unbiased Percent Error (MUPE), Minimum Percent Error with Zero Percent Bias Constraint (MPE- ZPB), and log-transformed Ordinary Least Squares (LOLS)...2009Models
