Pert stands for program evaluation review technique, a methodology developed by the u.s. Navy in the 1950s 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.
What Does Pert Stand For?
PERT, or the Program Evaluation and Review Technique, is a tool used by project managers to estimate the completion time of a project.
PERT was developed in the 1950s by the U.S. Navy to estimate the time needed to complete the development of a nuclear submarine. PERT is a statistical tool that uses the mean, mode, and standard deviation of a project to estimate its completion time.
PERT is often used in conjunction with the Critical Path Method (CPM), which is a technique used to identify the critical path of a project.
The critical path is the longest path through a project, and any delay in the critical path will delay the completion of the project. PERT and CPM are often used together to manage large projects. PERT is a three–step process:
1. Determine the activities that make up the project.
2. Estimate the time required to complete each activity.
3. Construct a network diagram that illustrates the relationships between the activities.
The PERT technique is based on three time estimates for each activity:
1. Optimistic time: This is the shortest time in which the activity can be completed.
2. Pessimistic time
