PERT
CV = EV ‐ AC CPI = EV / AC SV = EV ‐ PV SPI = EV / PV ETC = EAC ‐ AC EAC = BAC / CPI VAC = BAC – EAC EAC ‘fundamentally flawed’ = AC + ETC EAC ‘atypical’ = AC + BAC ‐ EV EAC ‘over budget + deadline’ = AC + ((BAC ‐ EV) / CPI * SPI)) ETC ‘atypical’ = BAC ‐ EV ETC ‘typical’ = (BAC ‐ EV) / CPI ETC ‘flawed’ = new estimate Percent Complete = EV / BAC * 100 EV = % complete * BAC TCPI ‘based on BAC’ = (BAC – EV) / (BAC – AC) TCPI ‘based on EAC’ = (BAC – EV) / (EAC – AC)
PERT 3‐point = (Pessimistic+(4*Most Likely)+Optimistic)/6 PERT = (P + 4MP + O) / 6 PERT σ = (Pessimistic ‐ Optimistic) / 6 PERT σ = (P ‐ O) / 6 PERT Activity Variance = ((Pessimistic ‐ Optimistic) / 6) ² PERT v = ( ( P ‐ O) / 6) ²
Communications
Probability
Communication Channels = n * (n – 1 ) / 2 Where “n” is the number of channels
EMV = Probability * Impact in currency EMV = P * I
Project Selection PV = FV / (1+r) ⁿ FV = PV * (1+r) ⁿ BCR = Benefit / Cost CBR = Cost / Benefit
Values to Remember 1 sigma = 68.26% 2 sigma = 95.46% 3 sigma = 99.73% Six sigma = 99.99% Pareto Diagram = 80/20
Network Diagram
Project Selection
EF = ES + duration ‐ 1 PV = FV / (1+r)^n ES = EF of predecessor + 1 FV = PV * (1+r)^n LF = LS of successor ‐ 1 BCR = Benefit / Cost LS = LF ‐ duration + 1 CBR = Cost / Benefit Activity Duration = EF ‐ ES + 1 or Rough Order of Magnitude estimate = ‐50% to +50% Activity Duration = LF ‐ LS + 1 Preliminary estimate = ‐15% to + 50% Total Float = LS ‐ ES or Budget estimate = ‐10% to +25% Total Float = LF – EF Definitive estimate = ‐5% to +10% Free Float = ES of Following ‐ ES of Present ‐ DUR of Present Depreciation Double Declining Balance Method: Sum‐of‐Years' Digits Method: Straight‐line Depreciation: Depreciation Rate = 2 * (100% / Useful Sum of digits = Useful Life + (Useful Depreciation Expense = Asset Cost (– Life) Life ‐ 1) + (Useful Life ‐ 2) + etc. Scrap Value) / Useful Life Depreciation Expense = Depreciation Depreciation rate = fraction of years Depreciation Rate = 100% / Useful Life Rate * Book Value at Beginning of Year left and sum of the digits (i.e. 4/15th Book Value = Book Value at beginning of year ‐ Depreciation Expense
