Activity Network (PERT) Chart

Activity Network and Project Evaluation and Review Technique, or PERT, charts are a way of documenting and analyzing the tasks in a project.
This diagram is constructed as part of the process in creating a schedule of corrective actions. The Activity Network Chart (PERT) shows the logical connections and consequence of tasks to be performed. It displays the time period for problem solving and the implementation of all activities through the critical path.
