Question
The following data is received from your contractor: Budgeted Cost of Work Performed (BCWP) = $200 Cost Performance Index (CPI) = 0.8 Budgeted Cost of Work Scheduled (BCWS) = $300 Schedule Performance Index (SPI) = 0.66 Actual Cost of Work Performed (ACWP) = $250 Budget at Completion (BAC) = $800 Contractor's Latest Revised Estimate = $900 Equation for Estimate at Completion (EAC) Low = ACWP+((BAC-BCWP)/(CPI)) Equation for EAC High = ACWP+((BAC-BCWP)/(CPI*SPI)) Which of the following represents the most reasonable EAC range for these data based on Earned Value Management (EVM)?
Explanation / Answer
EAC(low) = ACWP+((BAC-BCWP)/(CPI))
= 250 + (800-200)/0.8
= 250 + 600/0.8
= 250 + 750
= 1000
EAC (high) = ACWP +((BAC-BCWP)/(CPI*SPI))
= 250 + (800-200)/(0.8*0.66)
= 250 + 750/0.66
= 250 + 1136.36
= 1386.36
EAC range = $ 1000 - $ 1386.36
