Project Management: PERT and CPM (A Class Session, February 11, 2026)

Project Management: PERT and CPM PERT and CPM: Program Evaluation and Review Technique (PERT) and Critical Path Method (CPM) are network techniques developed to manage complex projects. Both methods help identify the relationships between project activities and the time required to complete them. Example(s) 1) NASA’s Apollo Space Missions: PERT was crucial for NASA’s Apollo space missions, allowing engineers to map out complex tasks and dependencies with uncertain outcomes. 2) The Hoover Dam Project: CPM was used in the construction of the Hoover Dam, ensuring the project stayed on its critical path and was completed on time despite massive logistical challenges. Key Points on PERT and CRM 1) Developed in the 1950s: CPM was created in 1957 by DuPont to manage chemical plant projects, while PERT was developed in 1958 by Booz, Allen & Hamilton, along with the U.S. Navy, for the Polaris missile project. 2) CPM by DuPont for Chemical Plants (1957): CPM focuses on the longest path of tasks, called the "critical path," which determines the project's minimum completion time. 3) PERT by Booz, Allen & Hamilton with the U.S. Navy for Polaris Missile (1958): PERT was developed to handle uncertain project timelines by estimating three time durations for each task—optimistic, pessimistic, and most likely. 4) Precedence Relationships and Interdependencies: Both techniques consider the order in which tasks must be completed and how they depend on one another. 5) Different Estimates of Activity Times: CPM usually uses fixed time estimates, while PERT uses a range of time estimates to account for uncertainty.
