Question 1 You are planning to conduct a series of telephone interviews. Your interview guide is ready, and each phone interview is independent of the others. You state the following in your project plan: Your project will last ten months. You will conduct 100 interviews each month. You will spend $300 to conduct each interview. Your total project budget is $300,000. During your first month, you do the following: Conduct 75 interviews. Spend a total of $15,000. You planned to conduct 100 interviews in the first month and you conducted only 75, thus, you are behind schedule. Since you planned to spend $300 per interview and you spent only $200 ($15,000 + 75 interviews = $200 per interview), you are under budget. 1. Determine the planned value (PV), earned value (EV), and actual costs (AC) for the month. 2. Determine your schedule variance (SV), cost variance (CV), schedule performance index (SPI), and cost performance index (CPI) for the month. 3. Comment your results for part 2 above. 4. Calculate your revised estimate at completion (EAC) as follows: Assume that the remaining work is performed at the originally budgeted rate. b. Assume that the remaining work is performed at the same CPI as the work performed to date.
