Explanation-

PERT stands for Program Evaluation and Review Technique, and it was designed to meet the needs of projects with unknown time and cost projections.

It takes a probabilistic approach and is hence appropriate for first-time initiatives or projects involving research & development.

Probabilistic time for completion of any activity can be found from optimistic time, pessimistic time, and most likely time.
