Initiation Process Group

Present Value PV= FV

(1+r)n

FV= future value

R= interest rate

n = number of time periods

Net Present Value The higher the better

Internal Rate of Return The higher the better

Benefit to cost Ration The higher the better

Pay Back Period The lower the better

Benefit to Cost Ratio The lower the better

Free Float or Free Slack Free Float ( A) = Early Start (B) – Earl y Finish (A)

Total Float or Total Slack Total Float (A) = Late Start ( A) – Early Start (A)

Total Float (A) = Late Finish (A) – Early Finish (A)

Cost Estimation Rough Order Magnitude (ROM) Estimate + or – 50%

Budget Estimate -10 to +25%

Definitive Estimates (2 options) + or -10% | -5 to 10%

Expected Monitory Value (EMV) Probability * Impact

Cost Variance (CV) Earned Value – Actual Cost | EV-AC

Schedule Variance (SV) Earned Value – Planned Value | EV-PV

Cost Performance Index (CPI) Earned Value / Actual Cost | EV/AC

Schedule Performance Index (SPI) Earned Value / Planned Value | EV/PV

Estimate at Completion (EAC)

At Present CPI

Budget at Completion / Cost Performance Index

EAC = BAC/CPI

Estimate at Completion (EAC)

At Budgeted Rate

Actual Cost +( Budget at Completion – Earned Value)

AC + (BAC-EV)

Estimate at Completion (EAC)

Considering both CPI and SPI

AC + ( BAC – EV_)

CPI * SPI

Estimate to Complete (ETC)

When original estimates are flawed

Estimate at Completion – Actual Cost | EAC - AC

Estimate to Complete (ETC)

When variances are typical

Budget at Completion – Earned Value | BAC- EV

Cost Performance Index CPI

To-Complete Performance Index

Based on Budget at completion

Budget at Completion – Earned Value | BAC - EV

Budget at Completion – Actual Cost BAC- AC

To Complete Performance Index

Based on EAC

Budget at Completion – Earned Value | BAC - EV

Estimate at Completion – Actual Cost EAC- AC

Variance At Completion (VAC) Budget at Completion – Estimate at Completion |

BAC - EAC
