The Program Evaluation and Review Technique (PERT) is a project management tool used to plan, schedule, and coordinate tasks within a project. It helps identify the minimum time required to complete a project by analyzing the time needed for each task and the dependencies between them. PERT is particularly useful for complex projects where time estimates are uncertain. PERT uses a visual representation called a PERT chart, which displays tasks as nodes and their dependencies as arrows. This method allows project managers to identify critical paths, optimize resource allocation, and improve overall project efficiency. It is widely used in various fields, including construction, software development, and research.
