PMI Scheduling Professional (PMI-SP) — Question 20

You are the project manager of the NHA Project. This project is expected to last one year with quarterly milestones throughout the year. Your project is supposed to be at the third milestone today but you're likely only 60 percent complete. Your project has a BAC of $745,000 and you've spent $440,000 of the budget-to-date.
What is your schedule performance index for this project?

Answer options

• A. 80
• B. 1.02
• C. 102
• D. 0.80

Correct answer: D

Explanation

The Schedule Performance Index (SPI) is calculated using the formula SPI = EV / PV, where EV is Earned Value and PV is Planned Value. In this case, the Earned Value (EV) is 60% of BAC, which is $447,000, and the Planned Value (PV) at this stage is $550,000 (75% of BAC for three milestones). Thus, SPI = 447,000 / 550,000 = 0.81, which rounds to 0.80, making D the correct answer. The other options do not reflect the correct calculations for SPI.
