  1. Budget at Completion (BAC)
    How much is budgeted for the total job
  2. Planned Value (PV)
    • Planned % complete x BAC
    • How much should be done?
  3. Earned Value (EV)
    • Actual % complete X BAC
    • How much work is done?
  4. Actual Cost (AC)
    How much has been spent?
  5. Cost Variance (CV)
    • EV – AC
    • >0 good; <0 bad
  6. Schedule Variance (SV)
    • EV – PV
    • >0 good; <0 bad
  7. Cost Performance Index (CPI)
    • EV / AC
    • >1 good; <1 bad
  8. Schedule Performance Index (SPI)
    • EV / PV
    • >1 good; <1 bad
  9. 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
  10. Estimate to Complete (ETC)
    • EAC – AC
    • BAC-EV atypical variance (will NOT occur ) in future
    • (BAC-EV) / CPI typical variance (will occur ) in future
  11. Variance at Completion (VAC)
    BAC – EAC
  12. To Complete Performance Index (TCPI)
    (BAC-EV) / (BAC – AC)
  13. PERT
    ( P + 4M + O ) / 6
  14. Standard Deviation (SD)
    (P-O) / 6
  15. Task Variance (TV)
    • [(P-O) / 6]2
    • Standard Deviation squared
  16. Project Variance
    • Square root of the sum of the Task Variance
  17. # of Communication Channels
    • N ( N-1 ) / 2 -OR-
    • ( N2 – N ) / 2
  18. Present Value (PV)
    • FV / ( 1 + R )T
    • R = Interest Rate
    • T = # of time Periods
  19. Future Value (FV)
    • PV x ( 1 + R )T
    • R = Interest Rate
    • T = # of time Periods
  20. Sigma Normal Distribution
    • 1 sigma = 68%
    • 2 sigma = 95%
    • 3 sigma = 99.7%
    • 6 sigma = 99.9%
  21. Expected Monetary Value (EMV)
    Probability x Impact
