Verification, Validation, and Accreditation (VV&A)

The field of modeling and simulation (M&S) has become an integral part of the systems acquisition process, augmenting design, development, and T&E while reducing program technical and cost risk. M&S can examine a broader tradespace in a shorter amount of time and at less cost than traditional T&E. As the complexity of these models has increased, model users have implemented verification, validation, and accreditation (VV&A) processes to assess and demonstrate the credibility of the M&S results used to support program decisions.
