Agile Software Development: Creating A Cost Of Delay Framework For Air Force Software Factories, J. Goljan, Jonathan D. Ritschel, Scott Drylie, Edward D. White

The Air Force software development environment is experiencing a paradigm shift. The 2019 Defense Innovation Board concluded that speed and cycle time must become the most important software metrics if the US military is to maintain its advantage over adversaries.1 This article proposes utilizing a cost-of-delay (CoD) framework to prioritize projects toward optimizing readiness. Cost-of-delay is defined as the economic impact resulting from a delaying product delivery or, said another way, opportunity cost. In principle, CoD assesses the negative impacts resulting from changes to the priority of a project.
Improving Acquisitions In Science And Technology Programs Through Factor Development And Program Analysis, Eric A. Plack
Improving Acquisitions In Science And Technology Programs Through Factor Development And Program Analysis, Eric A. Plack
Theses and Dissertations
This research involves a study of Air Force science and technology (S&T) programs which includes the creation of standard factors and a program analysis. There has been little prior cost research on S&T programs, which occur very early in the acquisition lifecycle. This leads the cost analyst to utilize estimating techniques such as analogy, factors, and parametric in order to develop budgets with minimal information. The absence of formal S&T cost reporting requirements and common cost elements necessitate a segregated two phased data analysis. The Factor Development phase accomplishes the development and creation of two new standard cost factors along …
Developing Standard Production Cost Factors For Major Defense Acquisition Program (Mdap) Platforms, Jordan S. Edwards
Developing Standard Production Cost Factors For Major Defense Acquisition Program (Mdap) Platforms, Jordan S. Edwards
Theses and Dissertations
Cost estimators commonly use the analogy and factor method when developing Major Defense Acquisition Program (MDAP) estimates. Previous studies discussing and developing factors for the production lifecycle phase have been limited in scope and statistical analysis efforts. This research significantly expands the currently available toolkit for Department of Defense cost analysts by updating the current database of historical data and exploring potential relationships through statistical testing. Specifically, 3,462 unique factors were created across nine level II Work Breakdown Structure (WBS) elements broken down into four categories; commodity type, contract type, contractor type, and service. The production cost factors were created …

This report contains the information and background on top-down cost estimating using artificial neural networks (ANN)_to enhance the accuracy of MDT early estimates of construction costs. Upon conducting an extensive review of MDT’s budgeting and cost estimating efforts, and following a survey of agency experts on the identification of the most salient project attributes with the dual-objectives of low effort and high accuracy, a rational method for top-down variable selection is proposed. Selected variables were further tested in their explanatory power of construction costs through the application of two cost estimating methodologies—multiple regression and artificial neural network methodologies. Both methods …

As the costs of Department of Defense (DoD) Weapon Systems increase, the ability to estimate the Operating and Support (O&S) costs accurately for the various weapon systems has become vital to long-term affordability. This research focuses on the O&S costs of the Air Force fixed-wing arsenal (i.e., platforms) for 1996–2016. First, the Cost Element Structure (CES) for 52 aircraft platforms and seven operational mission categories is analyzed to derive the descriptive statistics per aircraft category through examination of actual historical costs. Second, testing to identify statistical differences within the O&S CES construct across various Air Force aircraft categories is conducted. …

The first part of this manuscript examines the impact of configuration changes to the learning curve when implemented during production. This research is a study on the impact to the learning curve slope when production is continuous but a configuration change occurs. Analysis discovered the learning curve slope after a configuration change is different from the stable learning curve slope pre-configuration change. The newly configured units were statistically different from previous units. This supports that the new configuration should be estimated with a new learning curve equation. The research also discovered the post-configuration slope is always steeper than the stable …
A Comparative Study Of Learning Curve Models And Factors In Defense Cost Estimating Based On Program Integration, Assembly, And Checkout, Brandon J. Johnson
A Comparative Study Of Learning Curve Models And Factors In Defense Cost Estimating Based On Program Integration, Assembly, And Checkout, Brandon J. Johnson
Theses and Dissertations
The purpose of this research was to investigate the flattening effect at tail end of learning curves by identifying a more accurate learning curve model. The learning curve models accepted by DOD are Wright’s original learning curve theory and Crawford’s Unit Theory. The models were formulated in 1936 and 1944 respectively. This analysis compares the conventional models to contemporary learning curve models in order to determine if the current DOD methodology is outdated. The results are inconclusive as to if there is a more accurate model. The contemporary models are the DeJong and S-Curve and they both include an incompressibility …
