What is a project evaluation review technique (PERT)?

The project evaluation review technique (PERT) is primarily recognized as a tool for analyzing tasks involved in project completion. It is used to estimate the time required to complete each task within a project and to evaluate the interdependencies between these tasks. PERT focuses on the duration of individual activities and uses a statistical approach to account for uncertainty in the estimates. By representing the project's tasks and their sequences in a network diagram, PERT facilitates identifying the critical path, which is the longest sequence of tasks that need to be completed to ensure the project is finished on time.

This technique is particularly valuable in project management because it helps project managers to visualize and assess the timing and completion of various tasks, enabling better planning and scheduling. By understanding the relationships between tasks and their estimated durations, project managers can make more informed decisions regarding project timelines and resource allocation.
