Earned Value Management (EVM) Standards for 2026
Earned Value Management (EVM) is a project management methodology that integrates project scope, actual cost, and schedule timelines. Mandated on U.S. federal and major defense contracts (EIA-748), EVM answers: How much physical work has the team actually delivered compared to what was planned and what was spent?
A project that is under budget may not be doing well if it has only completed 30% of scheduled tasks. EVM reveals whether savings reflect genuine cost efficiency or missed project milestones.
EVM Performance Index Reference Table
| CPI / SPI Value | Status Definition | Meaning for Project Executives | Recommended Action |
|---|---|---|---|
| > 1.0 | Exceptional | Delivering more value than planned/spent | Document best practices; release contingency budget |
| 1.0 | Exact Target | Project executing precisely to baseline | Maintain baseline tracking cadences |
| 0.90 – 0.99 | Warning Zone | Slight cost overrun or schedule slip | Fast-track parallel tasks; control overtime |
| < 0.90 | Critical Risk | Severe overrun; project failing baseline | Conduct formal re-baselining or scope reduction |
The Core PMBOK EVM Equations
\text{Cost Variance (CV)} = EV - AC
\text{Schedule Variance (SV)} = EV - PV
\text{Cost Performance Index (CPI)} = \frac{EV}{AC}
\text{Schedule Performance Index (SPI)} = \frac{EV}{PV}
\text{Estimate at Completion (EAC)} = \frac{BAC}{CPI}
