PMP Formula of the Week: S-Curve

An S-curve for your project’s PV, EV and AC show AC above PV and EV below PV. What does this indicate?

A. On budget and on schedule.
B. On budget but behind schedule.
C. Over budget but on schedule.
D. Over budget and behind schedule.

Reveal Answer

The correct answer is D.

With AC, Actual Cost, above and higher than PV, Planned Value, (CV = EV – AC), the outcome in the formula is negative and the project is over budget. With EV, earned value, below and lower than PV (SV = EV – PV), the outcome is also negative and the project is behind schedule.
