Description / Abstract: This recommended practice defines the processes and procedures that should be followed to implement Verification, Validation, and Accreditation1 (VVA) for federations being developed using the High Level Architecture (HLA) Federation Development and Execution Process (FEDEP). This recommended practice is not intended to replace existing VVA policies, procedures, and guidance, but rather is intended to focus on the unique aspects of the VVA of federations. It provides a higher-level framework into which such practices can be integrated and tailored for specific uses. The VVA Overlay provides implementationlevel guidance to VVA practitioners; however, it does not describe the individual techniques that might be employed to execute the VVA processes for federations.

This VVA Overlay focuses upon the VVA processes that apply to federations and not the VVA processes associated with individual simulations (federates), but does consider using the information produced by those processes.

Users, developers, and VVA personnel working with simulations and simulation compositions not based upon the HLA and the FEDEP can also benefit from the guidance in this document since the activities that this overlay describes can be tailored to support any type of distributed simulation application.

Purpose

The VVA Overlay has been designed to apply across a wide range of functional applications. The purpose of this overlay is to provide a more detailed view of the VVA processes implied by the FEDEP. Currently, these processes represent the best practices available to the VVA community. The VVA Overlay is a tailorable process and is offered as guidance to all participants in FEDEP activities.
