A process node network plan is the form of a diagram for a network plan , in which the individual processes are displayed as boxes that are provided with important characteristics of the process (earliest start, latest start, earliest and latest end time, free buffer, total buffer, process duration, process name) . The processes are linked by arrows, which symbolize logical dependencies. The commonly used term PERT diagram is misleading because the original PERT uses event node networks.
