The Schedule Performance Index (SPI) is calculated as:

Show answer & explanation

Correct answer: Earned Value (EV) ÷ Planned Value (PV)

Explanation

SPI = EV/PV. An SPI > 1.0 means the project is ahead of schedule (more work was completed than planned). An SPI < 1.0 means the project is behind schedule. An SPI = 1.0 means the project is exactly on schedule. SPI is an earned value metric used to evaluate schedule efficiency.

**Why not B:** PV divided by AC does not yield a standard earned value metric. This formula does not measure schedule or cost performance and is not used in earned value management calculations.

**Why not C:** EV divided by AC calculates the Cost Performance Index (CPI), which measures cost efficiency, not schedule performance. CPI indicates whether the project is under or over budget, while SPI measures whether it is ahead or behind schedule.

**Why not D:** AC divided by BAC does not yield a meaningful earned value metric. This calculation would show what percentage of the total budget has been spent but provides no insight into schedule performance or efficiency.
