Budget at Completion (BAC)

How much is budgeted for the total job
Planned Value (PV)
- Planned % complete x BAC
- How much should be done?
Earned Value (EV)
- Actual % complete X BAC
- How much work is done?
Actual Cost (AC)

How much has been spent?
Cost Variance (CV)
- EV – AC
- >0 good; <0 bad
Schedule Variance (SV)
- EV – PV
- >0 good; <0 bad
Cost Performance Index (CPI)
- EV / AC
- >1 good; <1 bad
Schedule Performance Index (SPI)
- EV / PV
- >1 good; <1 bad
Estimate at Completion (EAC)
- BAC / CPI
- AC+ ETC original estimates are FLAWED or CAN’T be used
- AC + (BAC-EV) variance will NOT occur in future
- AC+((BAC-EV) / CPI) variance WILL occur in future
Estimate to Complete (ETC)
- EAC – AC
- BAC-EV atypical variance (will NOT occur ) in future
- (BAC-EV) / CPI typical variance (will occur ) in future
Variance at Completion (VAC)

BAC – EAC
To Complete Performance Index (TCPI)

(BAC-EV) / (BAC – AC)
PERT

( P + 4M + O ) / 6
Standard Deviation (SD)

(P-O) / 6
Task Variance (TV)
- [(P-O) / 6]²
- Standard Deviation squared
Project Variance
- Square root of the sum of the Task Variance
# of Communication Channels
- N ( N-1 ) / 2 -OR-
- ( N² – N ) / 2
Present Value (PV)
- FV / ( 1 + R )^T
- R = Interest Rate
- T = # of time Periods
Future Value (FV)
- PV x ( 1 + R )^T
- R = Interest Rate
- T = # of time Periods
Sigma Normal Distribution
- 1 sigma = 68%
- 2 sigma = 95%
- 3 sigma = 99.7%
- 6 sigma = 99.9%
