Earned Value Management (EVM)

Definition

Earned Value Management (EVM) is a project-management methodology for measuring program performance by comparing planned work (PV), earned value (EV), and actual costs (AC). It produces metrics like Cost Performance Index (CPI = EV/AC) and Schedule Performance Index (SPI = EV/PV) that quantify whether a program is over or under budget and ahead of or behind schedule. On DoW programs valued above $20M with development content, EVM compliance with the ANSI/EIA-748 standard and DFARS 252.234-7001/7002 is mandatory, and DCMA validates the contractor's Earned Value Management System (EVMS).

Why It Matters

EVM is the government's single most powerful tool for catching schedule slips and cost overruns early. For contractors, an EVMS-validated cost system is a major asset, signaling program-management maturity and unlocks eligibility for major-program work. For programs not formally requiring EVM, 'EVM-lite' disciplines (work packages, baselines, CPI/SPI tracking) still prevent the classic pattern of a program that appears on-budget until it suddenly isn't.

Example

A six-month into performance, a program's CPI drops to 0.85 and SPI to 0.90. The contractor identifies a staffing gap in one work package, adds resources, and recovers CPI to 0.95 within 90 days, all visible to the government through monthly Integrated Program Management Reports (IPMR).
