Critical Path Method — PMP - Project Management Professional Practice Questions
The Critical Path Method (CPM) is a network-based scheduling technique used to identify the longest sequence of dependent tasks that determines the minimum project duration. In CPM, the critical path consists of activities with zero float, meaning any delay to those tasks directly delays the project's finish date. The PMP exam tests candidates on calculating early start, early finish, late start, late finish, and float values through forward and backward pass analysis. Mastery of CPM is central to the PMP because it underpins schedule compression decisions such as crashing and fast tracking.

- Using Critical Path Method, a project has three parallel paths: Path A (12 days), Path B (10 days), and Path C (8 days). A team member asks if delaying a Path C task by 4 days impacts the schedule. What should the PM explain? Unlock answer & explanation →
- A project network has activities with the following relationships: Start → A(4) → B(5) → End; Start → C(3) → D(7) → End; A and C can run parallel, but D depends on both B and C completion. B has a finish-to-start lag of 2 days with D. What is the project duration? Unlock answer & explanation →
