PERT = (P+4M+O)/6
P = Pessimistic M= Most Likely O= Optimistic 
Standard deviation = (PO)/6 
Variance = {(PO)}/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*(N1)/2
Here N is number of member in project team If team have 10 member then =10 *(101)/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) = EVPV (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+BACEV 3. Current variance are Typical =AC+(BACEV)/CPI 4. Variance to continue at current rate = BAC/CPI 5. EAC = AC + [(BAC EV)/(CPI*SPI)] 
Estimate to complete (ETC) = EACAC 
Variance at complete (VAC) = BACEAC 
TCPI =
1. TO Complete performance index based on BAC= (BACEV)/(BACAC) 2. To complete performance index based on EAC= (BACEV)/(EACAC) 
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) ={(TCAC)*SSR}+TF TC = target cost AC = actual cost SSR= Sellers share ration TF= target fee
