Final answer:
The statement is true, PERT is a project management technique that uses multiple time estimates to plan and coordinate complex projects.
Step-by-step explanation:
The statement in question is true. The Program Evaluation and Review Technique, better known as PERT, is indeed a network-based project management technique that incorporates multiple time estimates for each activity. It includes three types of time estimates: (1) the optimistic time estimate (the shortest time in which an activity can be completed), (2) the most likely time estimate (the completion time having the highest probability), and (3) the pessimistic time estimate (the longest time an activity might take if everything goes wrong). PERT is particularly useful in planning and coordinating complex projects where the exact time required to complete each task is uncertain.
