Evolutionary acquisition: an analysis of defense procurement and recommendations for expanded use1

Abstract

United States Air Force (USAF) acquisition programs have historically suffered from extended acquisition cycle times and cost and schedule overruns. Department of Defense senior leadership has called for "transformation" of the acquisition process. In this article, we investigate an Evolutionary Acquisition (EA) strategy and the spiral development process. This article presents the case study analysis of three USAF acquisition programs: Global Hawk, B-2 Bomber, and Unmanned Combat Air Vehicle (UCAV). Data were collected through extensive literature review, interviews with acquisition experts from the three program offices, and completed questionnaires from members of Air Force Materiel Command’s (AFMC) Acquisition Center of Excellence (ACE), Aeronautical Systems Center’s (ASC) Transformation Team, and ASC’s ACE.
