Network Fundamentals

The major discrepancy with Gantt, milestone, or bubble charts is the inability to show the interdependencies between events and activities. These interdependencies must be identified so that a master plan can be developed that provides an up-to-date picture of operations at all times and is easily understood by all.

Interdependencies are shown through the construction of networks. Network analysis can provide valuable information for planning, integration of plans, time studies, scheduling, and resource management. The primary purpose of network planning is to eliminate the need for crisis management by providing a pictorial representation of the total program. The following management information can be obtained from such a representation:

• Interdependencies of activities

• Project completion time

• Impact of late starts

• Impact of early starts

• Trade-offs between resources and time

• Cost of a crash program

• Slippages in planning/performance

• Evaluation of performance

Networks are composed of events and activities. An event is defined as the starting or ending point for a group of activities, and an activity is the work required
