A project manager is using historical data from multiple projects to estimate activity durations. Which of the following network diagrams would BEST allow for the utilization of the information availa

CPM (Critical Path Method) focuses on determining the longest sequence of activities and typically uses a single, deterministic estimate for activity durations, which does not fully leverage historical data for probabilistic estimation.

GERT (Graphical Evaluation and Review Technique) is an advanced technique that allows for conditional branching and looping, which is more complex and not primarily focused on simple utilization of historical data for duration estimation.

CCM (Critical Chain Method) focuses on managing project buffers and resources, not on using historical data for probabilistic activity duration estimation.

PERT (Program Evaluation and Review Technique) is a project management tool specifically designed to analyze and represent tasks involved in completing a project, particularly useful for projects with uncertain activity durations. It utilizes a three-point estimation (optimistic, pessimistic, and most likely) often derived from historical data, which aligns with the need to utilize historical data from multiple projects for duration estimation.
