EARNED VALUE MANAGEMENT (EVM)
What is Earned Value Management?
Projects are governed by three fundamental constraints: scope, schedule, and cost. Conventional control systems often manage these dimensions independently, creating fragmented visibility and limiting predictive capability.
Earned Value Management (EVM) resolves this limitation by integrating scope, schedule, and cost into a unified, quantitative performance measurement framework. Transforming project controls from descriptive tracking into predictive performance intelligence.
The Core Earned Value Metrics
Earned Value Management performance evaluation is based on three primary variables:
| Metric | Term | Definition |
| Planned Value | PV | Authorized budget assigned to scheduled work. |
| Earned Value | EV |
Budgeted value of work actually performed. |
| Actual Cost | AC | Realized expenditure incurred for performed work. |
Earned Value Management Calculations
Performance Indices
These indices provide objective measures of schedule efficiency, cost efficiency, and overall project health.
Schedule Performance Index (SPI)
SPI = EV / PV
Cost Performance Index (CPI)
CPI = EV / AC
Critical Ratio (CR)
CR = SPI × CPI
Variance Analysis
Variance metrics provide immediate visibility into performance deviations, enabling early corrective intervention before systemic deterioration occurs.
Cost Variance (CV)
CV = EV − AC
Schedule Variance (SV)
SV = EV − PV
Forecasting Capability
Forecasting models derived from EVM provide statistically grounded projections of final cost outcomes and required performance efficiency.
Estimate at Completion (EAC)
EAC = BAC / CPI
Variance at Completion (VAC)
VAC = BAC − EAC
To‑Complete Performance Index (TCPI)
TCPI = (BAC − EV) / (BAC − AC)
Strategic Value of EVM
- Objective performance measurement
-
Early warning of trend deterioration
-
Integrated cost and schedule control
-
Predictive decision support
- Governance‑grade reporting
Conclusion
Earned Value Management is not merely a reporting technique. It is a quantitative control philosophy enabling organizations to measure execution efficiency, forecast outcomes reliably, and control project trajectories.
