PMP® Formülleri – 2

 

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 Index TCPI 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)
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

Working Capital Current Assets – Current Liabilities
Discounted Cash Flow Cash Flow X Discount Factor
Contract related formulas  Savings = Target Cost – Actual Cost

Bonus  =  Savings x Percentage

Contract Cost =  Bonus + Fees
