What is CPM (Critical Path Method)?

The Critical Path Method models a project as a network of activities with durations and dependencies, then computes the longest chain — the critical path — that determines the earliest possible finish. Any delay on the critical path delays the project.

In practice

CPM schedules in Primavera P6 or Microsoft Project are contractually required on most large projects. Their quality varies wildly, which is why schedule analytics and AI risk tools exist to grade and stress-test them.
