Assume you have completed three months of the project. The BAC was $200 000 for this six month project. Also assume the following: PV = $120,000 EV = $100,000 AC = $90,000 a) What is the cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project? b) How is the project doing?
