Cpm — PMP - Project Management Professional Practice Questions

CPM, or Critical Path Method, is a specific algorithm for project scheduling that calculates the longest path of dependent activities through a project network to determine the shortest possible project duration. The PMP exam expects candidates to perform CPM calculations manually, including identifying critical path activities, computing total float and free float, and understanding how changes to non-critical activities affect schedule risk. CPM is distinct from PERT in that it uses deterministic single-point duration estimates rather than probabilistic three-point estimates. This technique appears frequently in PMP quantitative scenario questions.
