a) What is the cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project?
• Cost Variance = Earned Value – Actual Cost
CV = 2,500,000 – 1,000,000
CV = 1,500,000 .
It's means the performing the work less than planned.
• Schedule Variance = Earned Value – Planned Value
SV = 2,500,000 – 5,000,000
SV = -2,500,000 . It's means it take longer than planned.
• Cost Performance Index = Earned Value / Actual Cost
CPI = 2,500,000 / 1,000,000
CPI = 2.5 . It's mean the project is over budget.
• Schedule Performance Index = Earned Value / Planned Value
SPI = 2,500,000 / 5,000,000
SPI = 0.5 / 100 = 50% . It's mean the project is behind schedule.
b) How much will it actually cost the company to complete this project, and how long will it really take to complete it based on the performance to date?
• To find the cost of company to complete this project use the CPI to calculate the estimate at completion (EAC).
Estimate At Completion = Budget At Completion / Cost Performance Index
EAC = 10,000,000 / 2.5
EAC = 4,000,000 . The project is performing better than planned since the new estimate to complete it is less than planned.
• To estimate how long it will take to finish this project use the schedule performance index (SPI).
Schedule Performance Index = 10 months / 0.5
SPI = 20 months.
c) What do you think of the project performance? over/under the budget? behind /ahead the schedule? Justify your answer.
Cost Performance Index (CPI) is the ratio of earned value to actual cost and can
be used to estimate the projected cost of completing the project. the cost performance index is 2.5 or 25% it's mean less than one or less than 100 percent, the project is over budget.
Schedule Performance Index (SPI) is the ratio of earned value to planned value
and can be used to estimate the projected time to complete the project. the schedule performance index is 0.5 or 50% it's mean less than one or 100 percent, the project is behind schedule.
