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.
Program evaluation and review technique
The critical path method CPM , or critical path analysis CPA , is an algorithm for scheduling a set of project activities. A critical path is determined by identifying the longest stretch of dependent activities and measuring the time  required to complete them from start to finish. The critical path method CPM is a project modeling technique developed in the late s by Morgan R. Walker of DuPont and James E. Kelley Jr. Critical Path Analysis is commonly used with all forms of projects, including construction, aerospace and defense, software development, research projects, product development, engineering, and plant maintenance, among others.
PERT and CPM are techniques of project management useful in the basic managerial functions of planning, scheduling and control. These days the projects undertaken by business houses are very large and take a number of years before commercial production can start. They minimise production delays, interruptions and conflicts. These techniques are very helpful in coordinating various jobs of the total project and thereby expedite and achieve completion of project on time. PERT is a sophisticated tool used in planning, schedu ling and controlling large projects consisting of a number of activities independent of one another and with uncertain completion times.
