Question

8.The relationship between the budgeted actual cost, actual work completed and work planned will determine the
Answer:
a. Cost estimate at completion

b. Cost performance index

c. Schedule performance index

d. Schedule estimate at completion

9.The measurement which best shows the difference between actual work and actual costs is
Answer:
a. Cost variance

b. Schedule variance

c. Percent over or under

d. CPI

10.Your most recent project status report contains the following information:
EV = 3,000
AC = 3,500
PV = 4,000

The schedule variance is:
Answer:
a. - 500

b. - 1,000

c. + 500

d. + 1,000

11.One common way to compute estimated at completion (EAC) is to take the project budgeted at completion and:
Answer:
a. divide it by the schedule perofrmance index

b. divide it by the cost performance index

c. multiply it by the schedule performance index

d. multiply it by the cost performance

Answer 1

8. Rate of performance = actual work completed / work planned
Earned Value = Planned Value x Rate of Performance
CPI = EV / AC
EAC = Budgeted Actual Cost / CPI
Answer a - Cost Estimate at Completion

9. The difference between actual work and actual cost
Percent over or under (answer c)

10. EV = 3,000; AC = 3,500; PV = 4,000
Schedule variance = EV - PV = 3000 - 4000 = -1000
(answer b)

11. EAC = project budgeted at completion divided by (CPI) cost performance index
(answer b)
