PMP · Question 43 · Task 6: Plan and manage schedule

A project has the following earned value metrics at month 10:<br/>- Budget at Completion (BAC): $1,200,000<br/>- Earned Value (EV): $720,000<br/>- Actual Cost (AC): $800,000<br/>- Planned Value (PV): $840,000<br/><br/>Calculate the Schedule Performance Index (SPI). Round to two decimal places and enter numbers only (e.g., 0.86).

How to approach this question

Calculate SPI using the formula: SPI = EV / PV. Divide Earned Value by Planned Value and round to two decimal places.

Full Answer

0.86
Schedule Performance Index (SPI) measures schedule efficiency by comparing earned value to planned value. An SPI of 0.86 indicates the project is behind schedule, accomplishing only 86% of the planned work.

Common mistakes

Students sometimes confuse SPI with CPI formulas or use AC instead of PV in the calculation.
