A graph shows the project's current cost and schedule performance. What should the project manager do to bring the project back on track?

The correct answer is to review the project schedule because the project is under budget and behind schedule. This scenario implies a Cost Performance Index (CPI) greater than 1 (under budget) and a Schedule Performance Index (SPI) less than 1 (behind schedule). The project has spent less than planned for the work completed, but has completed less work than planned by this point. The primary concern is the schedule delay, which could impact project objectives and stakeholder expectations. Reviewing the schedule will help identify the root causes of the delay and develop corrective actions to accelerate progress. The other options describe different performance scenarios or incorrect responses to the given scenario.
