23. Control Costs

26. Earned Value Management (EVM) Planned Value (PV) How much work should have been done? Earned Value (EV) How much work has been done? Actual Cost (AC) How much has been spent? Budget At Completion (BAC) What was the entire project supposed to cost? Estimate At Completion (EAC) What is the project expected to cost now?

27. Earned Value Management (EVM) Cost Variance (CV) Deviation from the original budget (in monetary terms)? Schedule Variance (SV) Deviation from the original schedule (in monetary terms)? Cost Performance Index (CPI) How well is the WBS component doing in terms of cost? Schedule Performance Index (SPI) How well is the WBS component doing in terms of schedule?

29. Summary of Formulae PV Planned Value Budgeted cost for the work scheduled EV Earned Value Budgeted amount for the work actually completed AC Actual Cost The total cost incurred BAC Budget at Completion Original budget CV Cost Variance EV – AC CPI Cost Performance Index EV / AC SV Schedule Variance EV – PV SPI Schedule Performance Index EV / PV ETC Estimate to Complete (BAC - EV) / CPI (assuming typical variances) EAC Estimate at Completion AC + ((BAC – EV) / CPI) or simply BAC / CPI VAC Variance at Completion BAC – EAC Estimated Time to Complete Original time estimate / SPI

30. Performance of Programming Project PV Planned Value $10K x 3 = $30K EV Earned Value $10K x 2 = $20K AC Actual Cost $16K BAC Budget at Completion $10K x 10 = $100K CV Cost Variance $20K – $16K = $4K CPI Cost Performance Index $20K / $16K = 1.25 SV Schedule Variance $20K – $30K = $-10K SPI Schedule Performance Index $20K / $30K = 0.67 ETC Estimate to Complete ($100K - $20K) / 1.25 = $64K EAC Estimate at Completion $16K + $64K = $80K $100K / 1.25 = $80K VAC Variance at Completion $100K - $80K = $20K Estimated Time to Complete
