Control Schedule

Monitors schedule status, measures progress against the baseline, and manages schedule changes, producing schedule forecasts. It keeps the timeline honest and the end date in view.

Control Schedule tracks how the project is progressing against the schedule baseline, measures variance, and forecasts the completion date. Earned value (schedule variance and SPI), trend analysis, and performance reviews show whether the project is on, ahead of, or behind plan.

Control Schedule: key inputs and outputs — The key inputs feeding Control Schedule and the deliverables it produces — full ITTOs are listed below.

When the schedule slips, the PM evaluates options — resource changes, leads and lags, or compression like fast-tracking and crashing — and routes genuine baseline changes through integrated change control. The focus stays on the critical path and any path approaching it.

Common pitfalls. Updating percent-complete optimistically and hiding slippage; reacting to the end date only when it’s too late; changing the baseline informally; and ignoring near-critical paths until they become critical.
