Under what circumstances is CPM a better technique than PERT?

CPM (Critical Path Method) is a better technique than PERT (Program Evaluation and Review Technique) when project activities are well-defined and have predictable durations, allowing for precise scheduling. It is particularly useful in projects where time is a critical factor and decision-making relies on optimizing resource allocation and minimizing project duration. Additionally, CPM is more effective for projects with repetitive tasks and where the focus is on managing costs and maintaining timelines.
