Which method is derived from an activity network diagram?

The Program Evaluation Review Technique (PERT) is specifically designed to analyze and represent the tasks involved in completing a project. PERT utilizes an activity network diagram, which visually depicts the sequence and interdependencies of various activities. By breaking down a project into individual tasks, PERT allows for estimation of the shortest, longest, and most likely time frames for project completion. The utilization of activity network diagrams in PERT enhances project planning and management by providing insights into timelines and potential bottlenecks.

This method is particularly valuable for complex projects where the relationships between tasks are critical for understanding overall project duration and efficiency. The clarity provided by the activity network diagram in PERT helps managers assess risk and allocate resources more effectively, contributing to successful project execution. Other methods listed, while relevant in quality management and analysis, do not primarily utilize an activity network diagram as their foundational element.
