| 1. PERT | (P + 4M + O )/ 6 Pessimistic, Most Likely, Optimistic |
| 2. Standard Deviation | (P – O) / 6 |
| 3. Variance | [(P - O)/6 ]squared |
| 4. Float or Slack | LS-ES and LF-EF |
| 5. Cost Variance | EV – AC |
| 6. Schedule Variance | EV – PV |
| 7. Cost Perf. Index | EV / AC |
| 8. Sched. Perf. Index | EV / PV |
| 9. Est. At Completion (EAC) | BAC / CPI,
AC + ETC — Initial Estimates are flawed AC + BAC – EV — Future variance are Atypical AC + (BAC – EV) / CPI — Future Variance would be typical |
| 10. Est. To Complete
Percentage complete |
EAC – AC
EV/ BAC |
| 11. Var. At Completion | BAC – EAC |
| 12. To Complete Performance IndexTCPI | Values for the TCPI index of less then 1.0 is good because it indicates the efficiency to complete is less than planned. How efficient must the project team be to complete the remaining work with the remaining money?
( BAC – EV ) / ( BAC – AC ) |
| 13. Net Present Value | Bigger is better (NPV) |
| 14. Present Value PV | FV / (1 + r)^n |
| 15. Internal Rate of Return | Bigger is better (IRR) |
| 16. Benefit Cost Ratio | Bigger is better ((BCR or Benefit / Cost) revenue or payback VS. cost)
Or PV or Revenue / PV of Cost |
| 17. Payback Period | Less is better
Net Investment / Avg. Annual cash flow. |
| 18. BCWS | PV |
| 19. BCWP | EV |
| 20. ACWP | AC |
| 21. Order of Magnitude Estimate | -25% – +75% (-50 to +100% PMBOK) |
| 22. Budget Estimate | -10% – +25% |
| 23. Definitive Estimate | -5% – +10% |
| 24. Comm. Channels | N(N -1)/2 |
| 25. Expected Monetary Value | Probability * Impact |
| 26. Point of Total Assumption (PTA) | ((Ceiling Price – Target Price)/buyer’s Share Ratio) + Target Cost |
