This document provides guidance on Earned Value Management (EVM) for NASA programs, projects, contracts and subcontracts. It summarizes NASA's EVM requirements, which require projects with a life cycle cost of $20 million or more to implement EVM. EVM is a project management process that integrates scope, schedule and cost elements to facilitate management and early identification of issues. The document outlines NASA's EVM policy, roles and responsibilities, and implementation processes for contracts and in-house projects. It aims to ensure consistent EVM application across NASA according to guidelines in the ANSI/EIA-748 Earned Value Management System standard.
