Recent requirements to establish the credibility of the models and simulations MS that are used in Department of Defense DoD applications have resulted in the development of several approaches to MS credibility assessment. Each of these approaches attempts to integrate verification and validation VV activities into a formal process whose products hopefully support MS accreditation. The cost of VVA activities has not typically been a driving factor in the development of these processes however and their independent and fragmentary development has tended to result in point-solution approaches to the problem of cost-effectiveness. Despite their diversity however many VVA processes share features in common suggesting that it may be possible to identify the essential elements of cost-effective VVA. This paper proposes five common sense elements of cost-effective VVA and describes how each of these elements can contribute to the cost-effectiveness of VVA processes in general. A comparative analysis of six VVA processes currently in use to support MS accreditation for a wide variety of DoD applications is then presented. The analysis reveals that the five elements proposed as essential to cost-effective VVA do in fact characterize in whole or in substantial part all of the VVA processes considered. The paper concludes by considering some of the evaluative implications of these findings.
