In August 1995, I commissioned a one year study with the objective of assessing the effectiveness of the use of modeling and simulation MS in the acquisition process. In particular, I was looking for the metrics by which the Department of Defense could ascertain the value-if any-that was returned on its investment in MS in terms of the reduction in time, resources, and risk in weapons systems development and fielding and in terms of increase in the military utility of those systems. I also tasked the study team while gathering information to support the assessment to note technical and other challenges to realizing the postulated benefits and to report on specific MS tools and processes being used to facilitate the acquisition of systems in the DoD and industry. This report, which documents the results of that study, provides tangible, quantitative indicators that the use of MS can provide substantial benefit measured in time, cost, productivity, and system quality and performance. The evidence is consistent and pervasive, across both DoD and industry. I personally was impressed that the most significant return on investment was realized when MS was used as an integrator of functions within the acquisition process, i.e., integrating design and manufacturing or linking requirements more closely to test. This leads me to believe that its real value lies as an enabler of Integrated Product and Process Development IPPD.
