From memory
Write the formula, then the number.
On exam morning, put these seven on the whiteboard before question one.
- BAC
- $200,000
- EV
- $80,000
- AC
- $100,000
- PV
- $90,000
The sheet
- CPIEV / AC
- SPIEV / PV
- CVEV − AC
- SVEV − PV
- EAC if the rate continuesBAC / CPI
- EAC if the overrun was one-timeAC + (BAC − EV)
- TCPI against the original budget(BAC − EV) / (BAC − AC)
- VACBAC − EAC. Negative means you expect to finish over budget.
Under 1 is unfavorable for CPI and SPI. Contingency is inside the baseline for known risks. Management reserve is outside it, for unknown unknowns.
