How Should We Estimate Agile Software Development Projects and What Data Do We Need?
Agile Track (AG01)
Tom Coonce
Glen Alleman

This paper proposes and demonstrates how to estimate agile software projects using collected data from prior similar projects. The authors discuss traditional ways of estimating software projects and show why these approaches are not feasible in estimating agile projects. They demonstrate estimating agile projects using actuals from historical features. They recommend a few additions to DoD’s Software Resource Data Report (SRDR) as well as a Standard Feature Breakdown Structure (FBS) to permit using this approach.

CMMI and Agile Development: A Binary Choice?
Agile Track (AG06)
Arlene F Minkiewicz

The Capability Maturity Model Integration for Development has a long and impressive history for progressing the cause of process improvement. Agile development is a paradigm for software projects that are characterized by collaborative, cross functional teams working closely with customers to deliver functionality regularly. Many say these two approaches can’t work in tandem. This paper explores this question with examples of both successes and failures.

Agile Delphi Estimating and Analyzing Schedule/Resource Realism for Software Projects
Agile Track (AG07)
Blaze Smallwood

One of the most important tasks for a software project manager is to accurately forecast the schedule and resources needed to complete the project. This paper will describe a novel approach to this problem that combines Monte Carlo-based uncertainty analysis with an innovative new technique for estimating software requirements, which utilizes an agile-style Delphi estimating methodology. This method has been successfully implemented on several government projects and is a viable option for any software project.

A Cost Model for Early Cost Calculation of Agile Deliveries
Agile Track (AG08)
Eric van der Vliet

Agile software development methodologies provide the IT industry with the flexibility they need to keep up with the faster change of business requirements. In agile software delivery, upfront detailed specifications are absent, yet investment decisions need budget input. The challenge is to build a cost model that takes essential (size) and additional cost drivers into account. This presentation explains a cost model that supports the cost calculation for agile delivery early in the process.

Production Rates: Do They Really Matter?
Data Analysis Track (DA03)
Brent Johnstone

Production rate is widely assumed to be an important contributor to unit cost — higher production rates lead to lower unit costs, and vice versa. Examination of published data, however, leads to a more ambiguous picture. This paper examines the impact of rate by functional cost element, including the impact on learning curves. It concludes production rate impacts are real, but the impacts are uneven and sometimes reveal themselves in surprising ways.

Lessons Learned in Leveraging Historical Cost, Schedule and Technical Data
Data Analysis Track (DA04)
Greg Kiviat

The process of applying historical cost, schedule and technical data to develop new program estimates is often more difficult than textbooks suggest. The paper provides real-world insight to the issues that arise when capturing, analyzing and applying data for the next estimate. The goal is to integrate information from multiple products, systems and subsystems. Lessons learned include experience and best practices when working with financial, engineering, manufacturing and program management.

Technology Readiness Level (TRL) vs. Percent Development Cost
Data Analysis Track (DA05)
James Linick

Advanced technology acquisition often proceeds in steps characterized by TRL of systems or components. The relationship between TRL ordinal number and percent of total acquisition cost could be used as a factor in estimating the cost of new acquisitions at each phase from concept definition through production decision. A study of historical data will be performed to establish such a relationship based on a specific definition of TRLs, which vary across government agencies.

Using Real Options to Quantify Portfolio Value in Business Cases
Economic Analysis Track (EA01)
George Bayer, Jr.

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.

Discount Rate for Government Investment
Economic Analysis Track (EA02)
Ron Beheler
Laura Barker

We 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.

Are the Rates Right? Benchmark Protection Against Escalation SWAG
Economic Analysis Track (EA03)
Brian Flynn
Brian Torgersen
Greg Mihalek
Adam James

Medical 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.

The Rate You Want – Rethinking Cost Escalation in FAA Development
Economic Analysis Track (EA04)
Sriram Krishnan
Andrew Drennon

Like 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.

Fully Integrated Cost & Schedule Method (FICSM) Analysis Schedule Implementation
EVM & Scheduling Track (EV04)
Dr. Jonathan Brown
Benjamin T. Unruh, Lt Col, USAF (Ret.)

The Joint Agency Cost Schedule Risk and Uncertainty Handbook released in March 2014 introduced the FICSM which integrates cost, schedule and risk estimating. Key to the FICSM process is creation of an analysis schedule including duration uncertainty. This study leveraged data from an active program to develop an analysis schedule as part of building a FICSM model. This paper describes the methods used to develop the analysis schedule and duration uncertainty used for this program.

Beyond RIFT: Improved Metrics to Manage Cost and Schedule
EVM & Scheduling Track (EV05)
Nicholas DeTore

“Risk-Informed Finish Threshold” (RIFT) presented an innovative solution to the problem inherent in schedules that risk analysis results (time) cannot be allocated the same way as in cost models (dollars). Developing RIFT validation methods inspired an exploration into analyzing simulation data more meticulously. Methods described here provide unique insight into cost and schedule uncertainty results while introducing powerful new techniques to improve a project’s potential to complete on time, on budget.

David L. Wang
Daniel Schwartz
David T. Chiang

Non-DoD federal acquisition agencies have their own unique acquisition requirements and acquisition culture. However, many non-DoD acquisition agencies face similar challenges, specifically in the areas of acquisition program execution and program affordability. To address these challenges, there has been increased interest to consider tailoring DoD best practices in Program Management, Earned Value Management and acquisition lifecycle schedule management. This presentation discusses a systematic approach to tailoring DoD best practices for non-DoD acquisition needs.

Cost Associated with Acquisition Complexity and Differing Levels of Mission Assurance
Methods Track (MM01)
Erik Burgess

In 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.

Don’t Dis LOE: Modeling Production Sustaining Labor Across Multiple Lots
Methods Track (MM02)
Sandy Burney

The estimation of sustaining labor is often given little analysis; just assuming some constant level. However, in estimating production hours on large Programs, spanning multiple lots, where each lot is negotiated separately, conflicts often occur over the cost of sustainment labor. This briefing will look at different approaches to estimating and modeling sustaining labor, based upon varying cycle times for completing a single unit, and the number of units being procured in each lot.

A Framework to Price and Cost IT Network Services
Methods Track (MM05)
John Leahy

The correct pricing of an IT network offering aimed toward internal users can be an involved process. Different services targeted to some, but not all customers makes proper cost allocation challenging. Considerations such as mirroring the structure, if not the rates, of commercial offerings; reconciliation of differences between cost allocations and rational pricing; and influencing customer purchasing behavior adds to the complexity. An approach for costing and pricing IT services that address these requirements will be presented.

Don’t Get Caught in the Learning Curve Vacuum
Methods Track (MM06)
Patrick McCarthy

Production environments featuring multiple end items benefit from a manufacturer designing products and processes with a high degree of commonality and standardization. When estimating labor hours using learning curves, the estimator often overlooks commonality when considering quantities, slope, production rate and lost learning. This paper will analyze alternative approaches to defining commonality and how to account for commonality using learning curves in integrated production environments.

Modeling Hardware Development Cost in a Low TRL / Pre-Acquisition Environment
Methods Track (MM08)
Jack Snyder

Estimating the cost of pre-concept programs, often with very immature TRL’s, is always challenging. This case study highlights the use of analogous programs and predictive modeling to overcome the challenge. We will explore the strategy of finding analogous components of a program, even when the overall program is unrelated. Predictive models can easily be tailored for the inherent uncertainty of these early programs, when we are unable to find relevant data.

Cost 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.

The 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.

The 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.

In Theory Or In Practice? The Optimistic World of Pessimistic Cost Estimators
Policy and Standards Track (PS02)
Erin K. Barkel

In 2015, Andy Prince won the Best Paper award for The Psychology of Cost Estimating, a piece which highlighted a number of cognitive biases which impact the work of cost estimators. Of these cognitive biases, the one that seemed to resonate most strongly with the community was optimism bias. However, not everyone is worried that the glass is half-full. Where do negativity and pessimism bias fit? How does our understanding of these biases change how we communicate with stakeholders?

How to Use Predictive Analytics for a DCAA-Compliant Estimating System
Policy and Standards Track (PS04)
Anthony A. DeMarco

The DCAA ensures that Defense contractors use an acceptable estimating. They establish acceptable estimating system compliance criteria and audit’s contractors to determine compliance. Non-compliance can be devastating. This presentation demonstrates a data-driven estimating methodology that complies and reduces the time and labor necessary to produce estimates. It illustrates the roles and procedures necessary for success. Six key compliance tenants are identified and key benefits quantified.

Developing a Cost Capability Roadmap
Policy and Standards Track (PS05)
John Fitch

Developing cost estimating tools and databases is critical to analyst productivity and the quality of analyses. Historically, organizations struggled to systematically improve capabilities due to a lack of a long-term plan, unstable budgets, and priorities that shift with changes in leaders. This presentation walks through how one organization confronted this challenge by developing a roadmap that links the mission to requisite tools, data, and training; and a plan to achieve the roadmap.

The Shortcomings of Cost Estimating Templates
Policy and Standards Track (PS06)
Meagan Gadreault
Faye Kim

Templates are seen as a best practice in many industries to standardize workflow and reduce redundancy. However, templates may not be the ideal solution for cost estimating as they can suppress innovation and constrain analysts. Instead, best practices should be determined using process improvement methods and implemented to create customized estimates. This paper explores leveraging Lean Six Sigma techniques to determine alternatives to templates in order to put forth the best estimates.

The Art of Cost: Sun-Tzu’s Strategic Insight in Cost Estimation
Policy and Standards Track (PS07)
Brian A. Gillespie

Strategy is the process employed to determine how political purpose is translated into action. Clausewitz in his grand work “”On War”” argued that war serves a political purpose. So too does cost estimation, for at its most fundamental level, cost estimation attempts to determine the level of resources needed to achieve a political outcome. As one of the greatest enduring works on military strategy, what does The Art of War teach us about cost estimation?

The need for a specialized, properly qualified DoD cost estimating workforce has resulted in a migration of civilian billets from a financially focused job series to the 1515 Operations Research series. We analyze the origins of this change, implications for the current workforce, and then discuss the anatomy of the future DoD cost analyst. While we focus on recent changes occurring within the U.S. Air Force workforce, the future implications are relevant to all Services.

A ‘Common Risk Factor’ Method to Estimate Correlations Between Distributions
Risk Track (RI02)
Marc Greenberg

A ‘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.

Reducing S-Curve Alchemy: Gold from a New SAR Database

S-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.

Integrated Cost-Schedule Risk Analysis Improves Cost Contingency Calculation
Risk Track (RI07)
David T. Hulett

The main benefits of integrated cost-schedule risk analysis are improvement of the estimates of cost contingency and identification of the main risks to cost for mitigation purposes. The main focus will be on estimating the cost contingency needed and identifying risks to cost, which may be independent of schedule or indirectly due to schedule risk. New simulation software including iterative risk prioritization will be used to illustrate these points.

Bottom Up Methods of Estimating Software SE/PM and Non-DCTI Costs
Software Track (SW02)
James Black

Systems Engineering/Program Management (SE/PM) and additional non-Design, Code, Test, and Integration (Non-DCTI) activities performed during software development efforts are often significant and drive estimates of total project costs. Yet, cost estimates often omit the detailed research and analysis needed to adequately model SE/PM & Non-DCTI costs. This brief will present bottom up methods useful for understanding and estimating these costs and share analysis of recent SE/PM & Non-DCTI data.

Jeremy Goucher

Software cost estimates require ratios derived from historic cost reports for non-design, code, test, and integration (NDCTI) cost elements. Since NDCTI accounts for as much as 50% of the estimate, a comprehensive historical data set is critical to ensuring an accurate estimate. The authors have recently analyzed over ten years of actual cost data from DoD command and control systems to develop a new set of NDCTI ratios. The results also bring new insight into “fixed” versus “variable” cost.

Objective SLOC: An Alternative Method to Sizing Software Development Efforts
Software Track (SW04)
Andrew Kicinski

Equivalent Source Lines of Code (ESLOC) is the basis of methodology used by many organizations for collecting and estimating software development costs. Selecting ESLOC parameters requires insight into the software reuse. Too often data collectors are unable to verify the appropriateness of the assigned ESLOC parameters and validate their implementation. This paper examines the drawbacks of ESLOC, and presents an alternative and more objective method to estimating software development effort.

Software Resources Data Reports (SRDR) are the DoD’s effort to improve cost estimation efforts by collecting metrics on software programs. Existing SRDRs were normalized in a manner consistent with previous efforts and productivities were analyzed using three popular software cost estimation models (SLIM, SEER, and COCOMO). Calculated values were tested against model thresholds and the results were tested for accuracy. Findings indicate some models outperform others and schedule impacts results.
