PERT (Program Evaluation and Review Technique) is a project management methodology used to schedule, organize, and coordinate tasks within a project. It is particularly useful for complex projects where time estimates are uncertain, as it incorporates probabilistic time estimates to calculate expected completion times.

PERT uses a network diagram to map out project tasks, identifying the sequence and dependencies between activities. It calculates the minimum time needed to complete a project by determining the critical path—the longest sequence of dependent tasks. Unlike deterministic models, PERT applies three time estimates for each task: optimistic, pessimistic, and most likely—allowing for risk assessment and more accurate forecasting.

This technique is commonly used in industries such as aerospace, defense, construction, software development, and research and development, where projects involve high uncertainty and require rigorous timeline planning. It is often used alongside other project management tools like the critical path method (CPM) and Gantt charts.

Develops project schedules using probabilistic time estimates
Identifies critical tasks and dependencies in project timelines
Supports risk analysis and decision-making under uncertainty
Used in complex, large-scale projects with uncertain durations
Integrates with project management software such as Microsoft Project or Primavera

Professionals skilled in PERT are typically found in project management, engineering, and operations roles. They are expected to understand network diagramming, task sequencing, time estimation techniques, and risk analysis. Mastery of PERT enables project managers to anticipate delays, allocate resources efficiently, and communicate realistic timelines to stakeholders.
