Program Evaluation and Review Technique (PERT) Introduction In today’s dynamic business environment, project management is crucial for achieving organizational goals efficiently. The Program Evaluation and Review Technique (PERT) is a powerful project management tool that helps managers plan, schedule, and control projects with uncertain durations. Developed by the U.S. Navy in the 1950s for the Polaris missile project , PERT has since been widely used in research & development, construction, and large-scale infrastructure projects. PERT is a probabilistic project scheduling technique that focuses on estimating the time required to complete each task while considering uncertainty. Unlike traditional project management methods, PERT provides a scientific approach to determining the expected project duration and identifying the critical path , which is essential for timely project completion. Features of PERT: Network-...

Use the formula: T E = ( O + 4 M + P ) 6 TE = \frac{(O + 4M + P)}{6} TE = 6 ( O + 4 M + P ) Given optimistic (O), mo...
