Science and technology (S&T) programs serve an important function in the defense acquisition process as the initial phase leading to discovery and development of warfighting technology. The results of these programs impact the larger major defense acquisition programs, which integrate the technologies in subsequent phases of the life cycle. Despite this important role, little prior research has examined the performance of S&T programs. In this study, the authors investigate the impact of technological maturation as a critical success factor in Air Force S&T programs. The results suggest that S&T programs with mature technologies are more likely to experience above average …

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 …
Acquisition Challenge: The Importance Of Incompressibility In Comparing Learning Curve Models, Justin R. Moore, John J. Elshaw, Adedeji B. Badiru, Jonathan D. Ritschel

The Department of Defense (DoD) cost estimating methodology currently employs T. P. Wrights 75-plus-year-old learning curve formula. The goal of this research was to examine alternative learning curve models and determine if a more reliable and valid cost estimation method exists, which could be incorporated within the DoD acquisition environment. This study tested three alternative learning models (the Stanford-B model, DeJong's learning formula, and the S-Curve model) to compare predicted against actual costs for the F-15 A-E jet fighter platform. The results indicate that the S-Curve and DeJong models offer improvement over current estimation techniques, but more importantly and unexpectedly …

Recent legislation, such as the Weapon Systems Acquisition Reform Act of 2009, requires a renewed emphasis on understanding Operating and Support (O&S) costs. Conventional wisdom within the acquisition community suggests a 70:30 cost ratio with respect to O&S and acquisition of an average weapon system. Using 37 Air Force and Navy programs, the authors estimate the mean overall ratio of O&S costs to acquisition costs to be closer to 55:45, although many weapon systems displayed significant deviation from this 55 percent average. Contributing factors such as life expectancy and acquisition strategy (i.e., new system or modification) affect this variance. Their …
Cost Overrun Optimism: Fact Or Fiction, David D. Christensen
Cost Overrun Optimism: Fact Or Fiction, David D. Christensen

Program managers are advocates by necessity, When taken to the extreme, program advocacy can result in the suppression of adverse information about the status of a program gram. Such was the case in the Navy's A-12 Program. In A-12 Administrative inquiry, Beach (1990) speculates that such abiding cultural problems were not unique to the Navy. To test that assertion, this paper examines cost overrun data on 64 completed acquisition contracts extracted from the Defense Acquisition Executive Summary database. Cost overruns at various contract completion points are compared with projected final cost overruns estimated by contractor and government personnel. 17 comparison …
