Explanation / Answer

1) Cost variance CV = Earned Value – Actual Cost = 55-67=-12 Negative value over budget

2) Schedule variance SV = EV – PV = 55-56=-1 Negative velue is small so bit over schedule

3) Cost performance index (CPI) = EV/AC=55/67 = 0.82=82%. Project is overbudget by 18%

4) Schedule performance index (SPI) = EV/PV = 55/56=0.98 less than 100% Schedule is on time with a value of 1 so the schedule is just slightly behind schedule at 98%.
