8、3) The HLA FEDEP (IEEE Std 1516.3-2003) is a recommended practice that describes a generalized process for building and executing HLA federations. It does not replace the existing management and development methodologies of HLA user organizations, but rather provides a high-level framework into whic

This recommended practice provides guidelines for verifying, validating, and accrediting a federation. Its purpose is to provide a m

This phase should result in a set of verified Federation Objectives and a Federation Referent and Federation Acceptability Criteria that adequately represent those objectives. 14 Copyright 2007 IEEE.
