Reviewing the earned value management results
The following are the earned value management (EVM) calculations and formulas used by Schedule Manager:
| Term | Formula / Definition |
|---|---|
| Planned Value (PV) | Budgeted Cost of Work Scheduled (BCWS) — planned effort to be done by now. |
| Earned Value (EV) | Planned Value (PV) multiplied by percent of work complete (or actual work) until now. |
| Actual Cost (AC) / Actual Cost of Work Performed (ACWP) | Actual hours of work performed on the task multiplied by the resource rate. |
| Cost Variance (CV) | EV − AC (in hours or cost). Greater than zero is considered good (under budget). |
| Budget at Completion (BAC) | The total budget or planned value (PV or BCWS) at the end of the project. |
| Forecast at Completion (FAC) | AC + (BAC − EV) |
| Estimate at Completion (EAC) | Projection of total cost of the project at completion: AC + (BAC − EV) / CPI |
| Schedule Variance (SV) | EV − PV (in hours or cost). Greater than 0 is considered good (ahead of schedule). |
| Schedule Performance Index (SPI) | EV / PV (ratio or %). Greater than 1 is considered good (ahead of schedule). |
| Cost Performance Index (CPI) | EV / AC (ratio or %). Greater than 1 is considered good (under budget). |
Based on the results, management can decide which projects should go forward.
Note: No baseline is considered in these calculations.
