Question

#3) Planned duration of a project is 28 weeks. Budget at completion for the project is $525,000. The project is in its 25th week. The actual cost (thus far) is $270,000. At this point in the plan, the planned cost was expected to be $261,000. For the work performed to date, the earned value is estimated at $272,000. Compute the following for the project (10 points) a) Cost variance. b) Schedule variance. c) If rest of the project is assumed to be completed at the current cost performance level, compute estimated total cost at completion of the project. d) If rest of the project is assumed to be completed at the current schedule performance level, compute estimated project completion time.

Answer 1

BAC = 525,000

Actual cost, (AC) = 270,000

Planned Value (PV) = 261,000

Earned Value (EV) = 272,000

a) Cost Variance = EV - AC = 272000 - 270000 = 2,000

b) Schedule Variance = EV - PV = 272000 - 261000 = 11,000

c) Cost Performance Index, CPI = EV/AC = 272000/270000 = 1.0074

Estimate At Completion (EAC) = AC + (BAC - EV)/CPI = 270000 + (525000 272000)/1.0074 = $ 521,142

d)

Planned Duration, PD = 28 weeks

Actual Time, AT = 25 weeks

Earned Schedule, ES = not given

Therefore, Estimated Completion Date (ECD) cannot be determined in absence of information about Earned Schedule (ES)
