What does the schedule performance index formula stand for?

  1. SPI = PV/EV

  2. SPI = EV - PV

  3. SPI = PV - EV

  4. SPI = EV/PV

The correct answer is: SPI = EV/PV

The Schedule Performance Index (SPI) is a formula used in project management to measure the progress or efficiency of the schedule performance of a project. The correct formula for SPI is SPI = EV/PV, where EV (Earned Value) represents the value of the work completed up to a certain point in time and PV (Planned Value) represents the value of the work planned to be completed up to that same point in time. By dividing the Earned Value by the Planned Value, you obtain the Schedule Performance Index, which indicates whether a project is ahead of or behind schedule.
