When Systems are Simulations: T&E, VV&A, or Both?June 1998
This paper provides a brief introduction on the use of modeling and simulation (M&S) and the importance of the credibility of that M&S when it is used to support system acquisition. A previous paper, The Relationship of VV&A to T&E (Allen et al. 1997), is briefly reviewed, followed by an introduction of a new example of M&S use. This example cites the recent development of systems that are themselves simulations. As new acquisition systems, they require traditional test and evaluation (T&E). As simulations, they require verification, validation and accreditation (VV&A) to ensure credibility. The main text of this paper examines key commonalties between these two processes. It provides insights into how T&E and VV&A requirementsí can be met with reduced cost and risk, to the optimal benefit of the user. A case study is provided and conclusions presented.
