| Question | Answer |
| BAC - Budget At Completion | Σ(PV) at project completion |
| EV - Earned Value | % complete x BAC |
| CV - Cost Variance | EV – AC (>0 is good) |
| SV - Schedule Variance | EV – PV (>0 is good) |
| CPI - Cost Performance Index | EV / AC (>1 is good) |
| SPI - Schedule Performance Index | EV / PV (>1 is good) |
| EAC - Estimate At Completion | AC / % Complete or BAC / CPI |
| ETC - Estimate To Completion | EAC—AC |
| VAC - Variance At Completion | BAC—EAC |
| TCPI - To Complete Performance Index | Remaining Work / Remaining Budget (BAC—EV) / (BAC—AC) or (BAC—EV) / (EAC—AC) |
| AC - Actual Cost | CV / (CPI - 1) |
| PV - Planned Value | SV / (SPI - 1) |
| Qualitative Risk Score | Probability x (Iscope + Itime + Icost + Iquality) |
| EMV - Expected Monetary Value | Impact x Probability |
| Communication Channels | N (N—1) / 2 N = # of stakeholders in the project |
| 1 Sigma = ? | 68.26% |
| 2 Sigma = ? | 95.46% |
| 3 Sigma = ? | 99.73% |
| 6 Sigma = ? | 99.999% |
| Present Value (PV) | FV --------------- (1 + r) ^ n FV = Future Value; r = Rate of Interest n = Number of Years |
| PERT - Program Evaluation and Review Technique | (O+4M+P) / 6 O = Optimistic P = Pessimistic M = Most Likely |
| SD of Activity (sigma) | (P-O) / 6 O = Optimistic P = Pessimistic |
| Variance of Activity | (SD) ^ 2 |
| Float | LS—ES = LF—EF LS = Late Start; LF = Late Finish ES = Early Start; EF = Early Finish |
