Here is list for pmp formulas.
| PERT = (P+4M+O)/6
P = Pessimistic M= Most Likely O= Optimistic |
| Standard deviation = (P-O)/6 |
| Variance = {(P-O)}/6 |
| Project PERT = Sum of PERT value of each task
|
| Project Variance = Sum of variance of each task |
| Normal distribution (sigma)
6 sigma = 99.99% 3 sigma = 99.73% 2 sigma = 95.46% 1 sigma = 68.26% |
| No of communication channel = N*(N-1)/2
Here N is number of member in project team If team have 10 member then =10 *(10-1)/2 =>10*9/2=>45 Communication channel |
| Float = LF – EF = LS- ES
LF = Late finish EF = Early finish LS = Late start ES = Early start Float value is 0(zero) on critical path. |
| Schedule variance (SV) = EV-PV (Positive variance is good)
EV = Earned value PV=Planned value |
| Cost Variance (CV) = EV- AC (Positive variance is good
EV = Earned value AC= Actual cost |
| Cost performance index (CPI) = EV/AC
(>1 are good) |
| Schedule performance index (SPI) = EV/PV
(>1 are good) |
| Estimate at complication (EAC) =
1. Estimating assumptions are not valid = AC+ETC 2. Current variance are atypical = AC+BAC-EV 3. Current variance are Typical =AC+(BAC-EV)/CPI 4. Variance to continue at current rate = BAC/CPI 5. EAC = AC + [(BAC -EV)/(CPI*SPI)] |
| Estimate to complete (ETC) = EAC-AC |
| Variance at complete (VAC) = BAC-EAC |
| TCPI =
1. TO Complete performance index based on BAC= (BAC-EV)/(BAC-AC) 2. To complete performance index based on EAC= (BAC-EV)/(EAC-AC) |
| Percentage complete of budget=(EV/BAC)* 100 |
| Benefit Cost Ratio (BCR) = Payback/project cost
Bigger is better |
| Net present value (NPV) bigger is better
Internal Rate of Return (IRR) bigger is better |
| Present Value PV= FV / ((1 + r)^term) |
| Expected Monetary Value = Probability * Impact |
| Procurement related
Actual cost (AF) ={(TC-AC)*SSR}+TF TC = target cost AC = actual cost SSR= Sellers share ration TF= target fee |
