A project sponsor asks if your project is ahead or behind schedule. What formula should you use to determine your answer?

A. PV – EV
B. EV – AC
C. EV – PV
D. EV ÷ SPI

Reveal Answer

The correct answer is C.

PV – EV, answers A, and EV ÷ SPI, answer D, are not meaningful formulas for this scenario. EV – AC, answer B, is the formula to determine Cost Variance (CV). The correct answer is EV – PV, answer C, as this formula is used to calculate Schedule variance (SV).
