A project manager applies trend analysis to schedule performance data across six reporting periods. She notices the Schedule Performance Index (SPI) decreasing each period: 1.05, 0.98, 0.91, 0.85, 0.79, 0.73. What conclusion is MOST supported?

Show answer & explanation

Correct answer: Schedule performance is deteriorating at a consistent rate and requires corrective action

Explanation

SPI below 1.0 indicates the project is behind schedule. A consistent downward trend (from 1.05 to 0.73) shows deteriorating performance over six periods. Trend analysis reveals this is not a one-time deviation but a systemic worsening, requiring significant corrective action to prevent further slippage.

**Why not A:** An SPI dropping from 1.05 to 0.73 over six periods is not within acceptable variance. The consistent downward trajectory clearly indicates a worsening problem, not normal fluctuation. Ignoring this trend would allow the schedule to deteriorate further without corrective intervention.

**Why not B:** SPI values below 1.0 indicate the project is behind schedule, not ahead. The data shows five of six periods with SPI under 1.0, meaning the project is progressively falling behind, making resource reallocation for other purposes inappropriate.

**Why not C:** The trend line is moving consistently downward, not recovering. Each successive period shows worse schedule performance than the last, with no sign of improvement or stabilization toward the 1.0 baseline.
