Earned Value Management (EVM) is a project performance measurement methodology that integrates scope, schedule, and cost data to provide objective assessments of project health and predictive forecasting capabilities. Developed from the U.S. Department of Defense's Cost/Schedule Control Systems Criteria (C/SCSC) in 1967 and standardized through ANSI/EIA-748, EVM enables project managers to quantify work performed against planned work and actual expenditures, revealing both schedule and cost variances early enough to enable corrective action. Unlike traditional project tracking that treats cost and schedule separately, EVM uses a common unit of measure—typically dollars—to answer three fundamental questions: What did we plan to accomplish? What did we actually accomplish? What did it cost us? This unified framework transforms subjective progress assessments into quantitative performance indices (CPI, SPI) and projections (EAC, ETC), making EVM the industry standard for performance measurement on complex government contracts, large-scale construction projects, and enterprise initiatives requiring rigorous cost-schedule integration and accountability.

Core EVM Concepts & Metrics
| Concept | Example | Description |
|---|---|---|
Project budget 500K, 40% scheduled = 200K PV | • Authorized budget assigned to scheduled work • also called Budgeted Cost of Work Scheduled (BCWS) • represents the physical work that should be accomplished by a specific date • calculated as PV = \text{Planned \% Complete} \times BAC• foundation for schedule variance calculation | |
35% work completed, 500K budget = 175K EV | • Measure of work performed expressed in budget terms • also called Budgeted Cost of Work Performed (BCWP) • represents value delivered regardless of actual expenditure • calculated as EV = \text{Actual \% Complete} \times BAC• central metric for both cost and schedule performance | |
Total expenditure to date = $190K AC | • Total costs incurred in accomplishing work performed • also called Actual Cost of Work Performed (ACWP) • includes direct and indirect costs • recorded from accounting systems • basis for cost variance and CPI calculation | |
Total project budget = $500K | • Sum of all budgets allocated to the project • represents total planned value at project completion • equals cumulative PV at 100% • forms denominator for % complete calculations • remains constant unless project is rebaselined |
