Presets
The Critical Path Method finds the longest chain of dependent tasks through a project — the sequence that sets the minimum completion time. Tasks on it have zero slack: delay any one and the whole project slips. Tasks off it can float. Stretch task B or D and watch the critical path re-route. The backbone of project management.

Reading this result: The critical path is A → B → D → F at 15 days. Tasks C, E carry slack — delaying them will not move the finish date, but any slip on a critical task pushes the whole project.
