Which method is used to identify the time required to complete tasks in project management?

The correct answer, PERT (Program Evaluation and Review Technique), is a project management method specifically designed to analyze and represent the tasks involved in completing a project. PERT is particularly useful for determining the time required to complete each task and the overall project timeline by examining the relationships between tasks.

This method utilizes a probabilistic approach, which involves estimating the shortest, longest, and most likely times to complete each task. By doing so, PERT helps project managers identify potential bottlenecks and areas of uncertainty in the project timeline. This enables more accurate scheduling and resource allocation throughout the project lifecycle, allowing for better management of project timeframes and expectations.

Other methods like the Critical Path Method focus on identifying the longest stretch of dependent activities and measuring project duration, while Gantt charts are primarily used for visualizing project schedules but do not specifically identify time estimations for tasks. Lean Management, on the other hand, is more focused on improving efficiency by eliminating waste rather than on task timing. Hence, PERT stands out for its specific functionality in estimating task completion time within project management.
