What is the formula to find the schedule performance index?

A.
EV-PV

B.
EV/AC

C.
EV/PV

D.
EV-AC

Explanation:
The schedule performance index shows how well the project is performing on schedule. It is found
by dividing the earned value by the planned value. Schedule variance (SV) is a measure of
schedule performance on a project. The variance notifies that the schedule is ahead or behind
what was planned for this period in time. The schedule variance is calculated based on the
following formula: SV = Earned Value (EV) – Planned Value (PV) If the resulting schedule is
negative, it indicates that the project is behind schedule. A value greater than 0 shows that the
project is ahead of the planned schedule. A value of 0 indicates that the project is right on target.
Answer option D is incorrect. EV-AC is the project’s cost variance.
Answer option B is incorrect. EV/AC is the project’s cost performance index.
Answer option A is incorrect. EV-PV is the project’s schedule variance.
