ABSTRACT

A network diagram shows project 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 between them show the order in which they should occur, e.g. put on shirt before tie, put on pants and socks before shoes, etc. (The diagram in Figure 6.1 is of course for illustration purposes only; any real-life attempt to plan work in such detail would be micro management and a real time-waster!) Ordinarily the boxes in the network would be the activities or work packages as defined in the work breakdown structure (WBS). Depending on the desired detail, however, they can represent any level of work, including projects in a program, sub-projects belonging to a project, or work packages in a project, subproject, or specific facility.
