### 1. Earned Value Management (EVM)

Definitions and Concept

• EV = Earned Value Management
• SV = Schedule Variance
• PV = Planned Value
• AC= ” Actual Cost
• CPI = Cost Performance Index : Behind/Over Budget > 1 > Ahead/Under of Budget
• SPI = Schedule Performance Index : Behind Schedule > 1 > Ahead of Schedule
• ETC = Estimate to Complete
• EAC = Estimate at completion (Forecasted Value based on performance)
• VAC = Variance at Completion (forecasted)

Formulas

• SV = EV – PV
• CV = EV – AC
• SPI = EV / PV
• CPI = EV / AC
• ETC = (BAC – EV) / CPI
• EAC = AC + ETC
• EAC = AC + (BAC – EV) : If future work will be completed at the planned rate
• EAC = BAC / CPI : If the CPI is expected to be the same for the remainder of the project
• VAC = BAC – EAC
• TCPI = (BAC – EV) / (BAC – AC)

### 2. Network Diagrams

• Activity Duration = EF-ES +1
• Total Float (TF) = LS – ES
• TF = LF – EF
• Free Float (FF) = ES(Successor) – ES(Present) – Dur(Present)

### 3. Project Estimation

• E (PERT Analysis/BETA Distribution) = (O + P + 4*M) / 6
• PERT Standrd Diviation σ = (P – O) / 6
• E (3-Point Estimate) = (O + P + M) / 3
• Var = σ(2)

### 4. Project Selection Methods

• Present Value PV = FV / (1 + r)n
• Future Value FV = PV * (1+ r )n
• NPV = ∑PV (This is sum of all PV)
• ROI = Return / Investment
• BCR = Benefits / Costs
• Payback Period = Initial Investment / Periodic CashFlow

### 5. Expect Monetary Value (EMV)

• EMV(R) = P*I
• EMV(P) = ∑EMV(R)
• Net Benefit = EMV(P) – Cost

### 6. Communication Channels

• C = n*(n – 1)/2

### 7. Procurement Management (Point of Total Assumption)

• Pt. of Total Assumption (PTA) = CP-TP/Buyer’s Share Ratio + TC

### 8. Risk Probability

• Expected Monetary Value (EMV) = Probability * Impact : always <1

### 9. Values

1 Sigma = 68.26%
