ABSTRACT
A network diagram shows a group of activities or tasks and their logical relationships – i.e., the “precedence relationships” or “dependencies” among the tasks. Figure 6.1 is a network diagram for “getting up in the morning and getting dressed” (for a male). The boxes represent activities or tasks, and the arrows connecting them show the order in which they should occur – for example, put on shirt before tie, put on pants and socks before shoes, etc. (The diagram in Figure 6.1 is of course intended for illustration only; any real life attempt to plan work in such detail would be “micromanagement” and a real time-waster!) Ordinarily for a project, the boxes shown in the network would be the activities or work packages as defi ned in the work breakdown structure (WBS). Depending on the desired detail, however, the activities in the network can represent work at any level, including projects in a program, subprojects belonging to a project, or the work packages belonging to a project, project phase, subproject or specifi c facility.
