This article presents a new methodology for assessing the risks associated with the level of verification, validation, and accreditation VVA of a given model andor simulation when used in support of major decisions. As stated by Department of Defense DoD Instruction 5000.61 DOD, 2003, It is DoD policy that models and simulations MS used to support major DoD decision-making organizations and processes shall be accredited for that specific purpose by the DoD component MS application sponsor. Instruction 5000.61 applies to All models and simulations developed, used, or managed by the DoD components after the effective date of this instruction. The requirements cited above have set the need for VVA of MS at the forefront of concerns for DoD and DoD-Component acquisition personnel. When an acquisition program involves a large number of models, cost associated with VVA can become enormous. There is a need therefore to have a systematic approach for assessing and prioritizing the risks associated with the level to which individual models have been verified, validated, and accredited. To provide decision-makers with a judicious way for determining the risks associated with using a given MS, and the extent to which VVA work will be needed to meet these requirements, a methodology is developed for assessing the risks associated with the level of VVA of a given MS when used to support decision-making. This approach parallels the formal DoD Risk Assessment procedure, but with application to the use of MS, as it relates to VVA.
