Factor Estimating is a technique commonly used by defense acquisition analysts to develop cost estimations. However, previous studies developing factors for the Engineering and Manufacturing Development (EMD) phase of the life cycle are limited. This research expands the current toolkit for cost analysts by developing cost factors in previously unexplored areas. More specifically, over 400 cost reports are utilized to create new standard cost factors that are delineated by five categories: commodity type, contract type, contractor type, development type, and Service. The factors are developed for those elements that are common in a wide array of projects such as program …

This study uses descriptive and inferential statistics to identify cost growth Analysis of Military Construction of military construction (MILCON) at the programmatic level, while bridging the gap between Selected Acquisition Report (SAR) estimates and actual project costs. Findings of this study aid the cost community with appropriate allocation of resources in developing these estimates. Overall, Major Defense Acquisition Programs (MDAP) appear to experience more negative growth (cost savings) in MILCON estimates on reviewed SARs— typically less than 0.2% of the total program cost. SAR estimates became more accurate from the first to last SAR in comparison to the total MILCON …

Legislation, in the form of acquisition reforms, is historically enacted to address perceived cost, schedule, and performance problems in the defense acquisition system. Text mining is utilized to examine five major reforms and a compendium of views from 32 acquisition experts to identify commonalities and disconnects.
Estimating An Acquisition Program’S Likelihood Of Staying Within Cost And Schedule Bounds, Ryan Trudelle, Edward D. White, Clay M. Koschnick, Jonathan D. Ritschel, Brandon M. Lucas

Program managers use prior experience to spot potential programmatic areas of concern. Augmenting this experience, the authors present an empirical procedure to estimate the likelihood of a program not exceeding two schedule and cost thresholds: (a) 15 percent of the initial total acquisition cost estimate from Milestone (MS) B to Initial Operating Capability (IOC); and (b) 15 percent of the estimated length (in months) between MS B and IOC—the second bound being 25 percent of the cost and schedule estimate. Using logistic regression and odds ratios, the authors analyze 49 Department of Defense programs and generally find that electronic system …

This research examines Cost Growth Factors (CGF) at various program stages for 30 Department of Defense aircraft programs. From Milestone (MS) B, the authors determine CGFs at the Critical Design Review (CDR), First Flight (FF), Development Test and Evaluation End, Initial Operational Capability (IOC), and Full Operational Capability. They find development CGFs are significantly larger than procurement CGFs. Additionally, cost growth primarily occurs early in the program. At CDR, which occurs on average at the 12 percent completion point of a program, aircraft programs had already experienced on average 15 percent of their total program cost growth. The first spike …
