Critical path method charts

PERT (Performance Evaluation Review, and Tracking) and CPM (Critical Path Method) charts (flowcharts) show the flow, connectivity, and interdependency of project tasks, activities, and goals. A PERT chart (Figure 27.9) depicts the activities in the order that they will need to be carried out, either in series or in parallel. These charts also identify which activities need to be completed (or initiated) before the next activity, which is dependent on it, can be initiated. 

The Gantt chart was invented by Henry Gantt in the early part of the last century. Gantt charts coordinate various activities (with a common ultimate goal) of various people. Such charts are the predecessor of the most powerful methods of the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT).
