Recall that PV is the planned value, EV is the earned value, AC is the actual cost, and BAC is the budget at completion. To receive credit, sh your we for all answers. PV=$77,000 EV=$67,000 AC=$51,000 BAC=$125,000 1. What is the cost variance (CV), schedule variance (SV), cost performance index (CPI), and schedule performance index (SPI) for this project? 2. How is the project doing? Is it ahead of schedule or behind schedule? Is it under budget or over budget? 3. Use the CPI to calculate the estimate at completion (EAC) for this project. 4.
