This guide provides the uniform procedures which have been approved by the Director, Defense Contract Management Agency (DCMA) under assigned authority as the Department of Defense's Executive Agent for Earned Value Management Systems (EVMS). This document has been coordinated by SAF/AQ, SAF/FM, ASA (ALT), ASN (RD&A), MDA/PO, NSA/CSS, and DCAA. This document provides guidance to be used during the implementation and surveillance of EVMS established in compliance with DoD Guidelines. Part I of this guide provides guidance for understanding EVMS concepts, describes objective guidelines for EVM systems, and provides guidance in interpreting those guidelines for use on Government contracts and programs. Part 2 contains a description of procedures and processes for Government personnel for specifying, evaluating, and implementing EVM systems. Part 2 also contains instructions and tailoring guidance for applying EVM requirements to contracts, an introduction to analyzing performance, baseline review and maintenance, and other post award activities. Additional reference material is contained in the appendices. It should be noted that Department of Defense (DoD) EVM policy not only applies to contracts with industry, but to intra-government activities as well. Throughout this document, the term "contract" refers to both contracts with private industry as well as agreements with intra-governmental activities that meet the DoD reporting thresholds. Similarly, the term "contractor" refers to entities within both private industry and Government. This document was developed to serve as the central EVMS guidance document for DoD personnel. Throughout the Earned Value Management Implementation Guide (EVMIG), additional references are made to additional sources of information, such as EVMS standards, handbooks, guidebooks, and websites. These additional sources should be consulted as appropriate.
