The Psychology of Cost Estimating
Andy Prince

Research 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.

The Navy Modernization Program:
Estimating the Cost of Upgrading AEGIS Guided Missile Cruisers

Jeremy Goucher
Krystian Jenkins

The Navy is well into its 20 year, $16B (CY10$) plan to modernize 84 AEGIS warships. This cost estimate covers eleven of the planned ships and accounts for maintenance and upgrades to the ship and the combat systems. The estimate leverages recent contract and shipyard performance data and interviews with engineers, resulting in a detailed study and recommended cost savings initiatives. The methods and data in this estimate will assist ship modernization cost efforts across the fleet for the foreseeable future.

Generalized Degrees of Freedom (GDF)

Minimum-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.

Improvement Curves:
An Early Production Methodology

Brent Johnstone

Learning 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.

Beyond Correlation: Don’t Use the Formula That Killed Wall Street
Christian Smart

Risk 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.

Early Phase Software Cost and Schedule Estimation Models
Wilson Rosa
Software Estimating Track

Software cost estimates are more useful at early elaboration phase, when source lines of code and Function Points are not yet available. This study introduces effort estimation models using functional requirements as a size predictor and evaluates development schedule using estimated effort based on data from 40 military and IT programs delivered from 2006 to 2014. Statistical results show that estimated functional requirements and peak staff are significant contributors and that estimated or actual effort is a valid predictor of development duration.

Wednesday morning’s keynote is on board! Dennis Conner captained the Stars and Stripes in the America’s Cup yacht race a total of six times: winning four and losing twice. His experience organizing everything that is required for a race, from situating the most minute details to leading a team of experts, is not unlike what our analysts, estimators, project and program managers go through every day – with the added threat of sea sickness! Read more about Dennis and his experience here.

Tuesday morning will start off with Retired Naval Commander Greg Cotten, the former Deputy Commander for Undersea Rescue with Submarine Squadron ELEVEN in San Diego. Greg will provide a brief history of submarine rescue, discuss the current status of the world’s capability, and ultimately present the challenges of cost estimating and analysis required to deliver predominately fixed price contracts to submarine escape and rescue services.
