Title Expansion of Enterprise Requirements and Acquisition Model.
Publication Date Jun 2012
Media Count 70p

Abstract Air Force senior leadership has continued to emphasize the need for progress on improving cost and schedule estimates for military acquisition programs. The Enterprise Requirements and Acquisition Model (ERAM) as modified by Leach and Searle is a quantitative discrete-event process simulation model accounting for activities from early capability analysis through system fielding of ACAT I space acquisition programs. This research seeks to modify the existing model by including ACAT II/III programs along with modeling the Rapid Acquisition process for space programs using the same methodology and techniques. The model begins with identification of a desired space capability early in the Joint Capabilities and Integration Development System (JCIDS) process through system development at Milestone-C (MS-C) of the acquisition system resulting in a probabilistic schedule distribution for a given concept. The research focused on identifying activities and assigning duration distributions and probabilities based upon past programs at each decision point. Data was collected through analysis of applicable policy, instructions, and journal articles as well as interviews with subject matter experts (SME) from the Air Staff, AFSPC and the Space and Missile Systems Center (SMC). ERAM has been utilized at SMC's space Concept Design Center (CDC) providing program managers insight into program duration estimations and probabilities of program success for concepts based on historical comparisons. Defense Acquisition University has also found interest in ERAM to be used as a training tool for personnel to better understand required procedures needed to acquire a space capability on schedule and within budget.
