CAPM Practice: Determine how to document project controls of predictive, plan-based projects

Question 32 of 85 in Determine how to document project controls of predictive, plan-based projects

A project manager monitors project performance using earned value metrics. At the midpoint of the project, she finds SPI = 1.1 and CPI = 0.92. What is the BEST description of the project's status?
Show answer & explanation

Correct answer: The project is ahead of schedule but over budget

Explanation

SPI = 1.1 means the project is ahead of schedule (doing more work than planned — for every dollar of work planned, $1.10 has been completed). CPI = 0.92 means the project is over budget (for every dollar spent, only $0.92 of value is earned). The combination is 'ahead of schedule but over budget' — possibly due to using higher-cost resources to accelerate work.

**Why not B:** This interpretation is incorrect because SPI = 1.1 indicates the project is ahead of schedule, not behind. An SPI greater than 1.0 means more work has been completed than was planned, so the project is performing better than planned on schedule.

**Why not C:** While the SPI = 1.1 correctly indicates ahead of schedule, the CPI = 0.92 means the project is over budget, not under budget. A CPI below 1.0 means less value is being earned per dollar spent, indicating cost overrun.

**Why not D:** The project is neither on schedule nor under budget. SPI = 1.1 shows the project is ahead of schedule (not merely on schedule), and CPI = 0.92 shows it is over budget (not under budget). Both metrics deviate from the 1.0 baseline.
