What is the formula you use in order to find the EAD in Triangular Distribution?
EAD = (O + M + P) / 3
What is the PERT formula you use in order to find the EAD in Beta Distribution?
EAD = (O + 4M + P) / 6
What formula do you use to find the Standard Deviation (SD) of an activity?
SD = (P - O) / 6
What formula do you use to calculate the variance of an activity?
Variance = ((𝑃 − 𝑂) / 6) ^2
What formula do you use to calculate the range of an activity duration?
Range of Activity Duration = EAD ± 𝑆𝐷
What formulas can you use to calculate the Total Float?
Total Float = Late Start (LS) – Early Start (ES)
or
Total Float = Late Finish (LF) – Early Finish (EF)
How do you calculate the CV (Cost Variance)?
CV = EV−AC
How do you calculate the SV (Schedule Variance)?
SV = EV−PV
How do you calculate the Cost Performance Index (CPI)?
CPI= EV / AC
How do you calculate the Schedule Performance Index (SPI)?
SPI = EV / PV
How do you calculate the Budget at Completion (BAC)
Usually given to you, but BAC = Total activity cost estimates + Total contingency cost reserves
How do you calculate the Estimate to Complete (ETC)?
ETC = EAC−AC
How do you calculate the Earned Value (EV?)
EV = Actual % Complete x BAC
How do you calculate the Planned Value (PV)?
PV = Planned % Complete x BAC
How do you calculate the Estimate At Completion? (EAC)
EAC = BAC / CPI
How do you calculate the Variance At Completion?
VAC = BAC - EAC
How do you calculate the To Complete Performance Index (TCPI)?
TCPI = (BAC - EV) / (BAC - AC) *If on budget TCPI = (BAC - EV) / (EAC = AC) *If over budget
What is the formula to find the Communication Channels for a project?
N x (N-1) / 2
What is the fomula for a foward pass?
ES + Duration - 1
What is the formula for a backward pass?
Late Finish - Duration + 1
What is the formula for present value?
PV = FV / (1+i)^n
What is the formula for EAC?
- AC + Bottom Up ETC
- BAC /CPI
- AC + (BAC - EV)
- AC + (BAC - EV) / (CPI x SPI)
How do you find the expected Monetary Value? (EMV)
EMV (cost) = P x I
EMV (schedule) = P x I
