Forward Pass
Early Finish = early start + duration
if multiple predecessor, use LATEST EF
Backward Pass
Late Start = late finish - duration
If multiple successors, use EARLIEST LS
Total Float
Total float = late finish - early finish
Variance - triangular distribution
V = [(A-B)^2 + (M-A)(M-B)] / 18
Standard Deviation
S = square root of the variance
Weighted-Average or Beta/PERT Distribution
Mean = (O + 4ML + P) / 6 SD = (P-O) / 6 O=optimistic ML=most likely P=pessimistic
Planned Value
The budget or portion of the approved cost estimate planned to be spent during a given period.
Actual Cost
The total direct and indirect costs incurred in accomplishing work during a given period.
Earned Value
The budget for the work accomplished in a given period.
Equations for Earned Value Management
Cost Variance = EV - AC
Schedule Variance = EV - PV
Cost performance index = EV / AC
Schedule performance index = EV / PV
Performance Domains::Process Groups
Initiating Planning Executing Monitoring and Controlling Closing
Estimate at Completion (EAC)
Expected total project cost on completion and as of the “data date” (time now)
New Estimate for EAC
Original estimate fundamentally flawed/no longer accurate.
EAC = AC + new estimate for remaining work
Original Estimate (EAC)
Actual variance seen as the exception. Original estimates seen as more accurate than what’s been seen.
EAC = AC + (BAC - EV)
B = budgeted
Performance Estimate Low (EAC)
Future variance likely like current variance.
EAC = BAC / CPI
Performance Estimate High (EAC)
Project over budget and schedule impacts work remaining
EAC = AC + (BAC - EV) / (CPI)(SPI)
Remaining Budget
Remaining Planned Value
BAC - EV
Estimate to Complete (ETC)
Estimate for completing the remaining work for a scheduled activity.
