Assume that ABC Company has invested a budget of 36 million riyals for XY project and planned to complete in 12 months. Let’s also assume that the company planned to spend the budget equally in each month. However, when the first two months has passed, the project manager has found out that the total of two million riyals spent.
Based on the above scenario, answer the following:
Suppose RP=0.25
a) What is the cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project?
a) Earned value (EV) = Rate of performance (RP) * Planned value (PV)
0.25 * 6,000,000 = 1,500,000
- cost variance (CV) = Earned value( EV) – Actual cost ( AC)
1,500,000 – 2,000,000 = -500,000
- Schedule variance (SV) = Earned value (EV) – Planned value (PV)
1,500,000 - 6,000,000 = - 4,500,000
- cost performance index (CPI) = Earned value (EV) / Actual cost ( AC)
1,500,000 / 2,000,000 = 0.75
- schedule performance index (SPI) = Earned value (EV) / Planned value (PV)
1,500,000 / 6,000,000 = 0.25
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?
b) Estimate at completion (EAC) = BAC / CPI
36,000,000 / 0.75 = 48,000,000
Estimate time to complete = original time estimate / SPI
12 / 0.25 = 48 month
c) What do o you think of the project performance? over/under the budget? behind /ahead the schedule? Justify your answer. |
c)
Project is costing more than planned (over budget) and taking longer than planned (behind schedule)
Because the invested budget = 36 million riyals and the Estimate at completion (EAC) = 48,000,000 and it was planned to finish in 12 month but Estimate time to complete = 48 month
