Critical Path
Scheduling Terms
Reviewed by forProject Technology - updated Sep 2026
Quick definition: The Critical Path is the sequence of linked tasks that determines the project's finish date. Delay any task on it and the project finishes later.
The Critical Path is the longest continuous chain of dependent tasks through the schedule. Every other path is shorter, so those paths have Float and can absorb some delay. The Critical Path can't. Tasks on it have little or no Float, so a slip on any of them moves the finish date. The Critical Path Method (CPM) is the technique used to calculate it.
What this means for you
The Critical Path shows the path through the schedule that is driving the project finish date. Delays elsewhere can often be absorbed by Float, but a delay on the Critical Path pushes out the finish date.

FAQ
What's the difference between the Critical Path and the Near Critical Path?
The Critical Path has the least float in the schedule (often zero). The Near Critical Path is the pathway with the next-lowest float — the one most likely to become critical if conditions change slightly.
Does the Critical Path ever change during a project?
Yes. As tasks are completed, delayed, or re-sequenced, the Critical Path can shift to a different sequence of tasks.
