Given the following information for a one-year project answerthe following questions. Recall that PV is the planned value. EV isthe earned value AC is the actual cost and BAC is the budget atcompletion.PV = $23000EV = $20000AC = $25000BAC = $120000a. What is the cost variance schedule variance cost performanceindex (CPI)and schedule performance index (SPI) for the project?b. How is the project doing? Is it ahead or schedule or behindschedule? Is it underbudget or over budget?c. Use the CPI to calculate the estimate at completion (EAC) forthis project. Is theproject performing better or worse than planned?d. Use the schedule performance index (SPI) to estimate how long itwill take tofinish this project.
