The Relationship of Technology and Design Maturity to DoD Weapon System Cost Change and Schedule Change During Engineering and Manufacturing Development,

Abstract

ABSTRACTEvery year, the Department of Defense (DoD) invests billions of dollars on the development of major defense acquisition programs. In return, many of these weapon systems have been plagued with cost overruns and schedule delays during the Engineering and Manufacturing Development (EMD) phase. Under conflicting guidance, DoD and the Government Accountability Office (GAO) suggest that weapon systems should contain subsystems with relatively mature technologies (based on the Technology Readiness Level of critical technologies) and design mature (based on the percentage of releasable design drawings) during system development. However, there has been no published research to date on the relationship between technology and design maturity guidance and the resulting cost change and schedule change of DoD weapon systems. The research presented in this paper confirms that the GAO guidance for design maturity can lead to a reduction of cost growth and schedule slippage of DoD weapon systems. In contrast, the research indicates that technology maturity guidance only impacts the schedule change of weapon systems, and not the potential cost change. With the quantitative results from the research, DoD and GAO officials can provide additional guidance to the planning and execution of the EMD phase, such as allocation of research and development funds to maturity achievement efforts.
