Representing Project Plans-Representing and Scheduling Project Plans
Representing Project Plans
Project scheduling and management requires that time, costs, and resources be controlled. Resources are any person, group of people, piece of equipment, or material used in accomplishing an activity. Network diagramming is a critical path scheduling technique used for controlling resources. A critical path refers to a sequence of task activities whose order and durations directly affect the completion date of a project. A Network diagram is one of the most widely used and best-known scheduling methods.
A major strength of Network diagramming is its ability to represent how completion times vary for activities. Because of this, it is more often used than Gantt charts to manage projects such as information systems development where

variability in the duration of activities is the norm. Network diagrams are composed of circles or rectangles representing activities and connecting arrows showing required work flows, as illustrated in Figure 3-22.
