The processes of Verification, Validation, and Accreditation are foundational elements that underlie assessments of M&S credibility. Verification and Validation (V&V) activities serve to build an evidentiary chain of information upon which M&S Users can assess the viability of an M&S for a particular application. Information derived from the V&V processes is used to shape the understanding of how and where an M&S should be used and under what the constraints.

While V&V is founded on basic software engineering principles, implementation is often constrained by resources, whether these resources be time, money, personnel, or information. This tutorial will address the key steps that can be taken to build strong V&V evidence while accounting for resource impacts. The tutorial will incorporate lessons learned derived from multiple VV&A applications.

Topics to be covered by this tutorial will include:

• Requirements traceability that provides the link between requirements and V&V testing
• Identifying verification test strategies (e.g., leveraging information, supplemental test activities)
• Building and applying validation referent data (what the simulation results will be compared to)
• Defining the simulation measures and metrics to use as the basis of comparison (the aspects of the results that will be compared to the referent)
• Selecting validation methods to apply when performing the results/referent comparison
• Documentation templates and tools that provide efficiency of process to the V&V effort

The tutorial will enhance the learning experience by incorporating lessons learned derived from the many VV&A applications with which the authors have been involved.
