Critical path method - WikipediaA PERT chart is a project management tool used to schedule, organize, and coordinate tasks within a project. Navy in the s to manage the Polaris submarine missile program. A similar methodology, the Critical Path Method CPM was developed for project management in the private sector at about the same time. A PERT chart presents a graphic illustration of a project as a network diagram consisting of numbered nodes either circles or rectangles representing events, or milestones in the project linked by labelled vectors directional lines representing tasks in the project. The direction of the arrows on the lines indicates the sequence of tasks. In the diagram, for example, the tasks between nodes 1, 2, 4, 8, and 10 must be completed in sequence.
PERT and CPM: Techniques of Project Management (Advantages and Disadvantages)
The program or project evaluation and review technique PERT is a statistical tool used in project management , which was designed to analyze and represent the tasks involved in completing a given project. First developed by the United States Navy in the , it is commonly used in conjunction with the critical path method in the year CPM. PERT is a method of analyzing the tasks involved in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project. It incorporates uncertainty by making it possible to schedule a project while not knowing precisely the details and durations of all the activities. It is more of an event-oriented technique rather than start- and completion-oriented, and is used more in these projects where time is the major factor rather than cost. It is applied on very large-scale, one-time, complex, non-routine infrastructure and on Research and Development projects. PERT offers a management tool, which relies "on arrow and node diagrams of activities and events : arrows represent the activities or work necessary to reach the events or nodes that indicate each completed phase of the total project.
