CAPM Practice: Demonstrate an understanding of a project management plan schedule

The project schedule should be updated regularly (typically weekly or bi-weekly) to reflect actual progress, and immediately after significant changes or events. Regular updates maintain an accurate view of current status and forecasts, enabling timely corrective action when the project deviates from the baseline.

**Why not A:** Updating only when the sponsor requests it is too passive. The project manager is responsible for maintaining an accurate schedule as part of ongoing project management, not waiting for external direction to perform this fundamental duty.

**Why not B:** Updating only when activities are completed ignores in-progress work that may be running ahead or behind schedule. Progress on active activities provides essential information for forecasting and early warning of potential problems.

**Why not D:** Waiting until the project is more than 10% off baseline before updating means the schedule is already significantly outdated. Regular updates are needed to detect variances early, when corrective action is still feasible and less costly.
