PMI Exam PMI-SP Topic 7 Question 49 Discussion

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.
