PERT is a project management technique whereby planning, scheduling, organizing, coordinating, and controlling uncertain activities are done. CPM is a statistical technique of project management in which planning, scheduling, organizing, coordinating, and controlling well-defined activities occur. The PERT CPM network diagram illustrates that PERT deals with unpredictable activities, but CPM deals with predictable activities. PERT is used where the nature of the job is non-repetitive. PERT charts make it easy to visualize and organize complex projects illustrating the dependencies between each step in the project.
