Introduction to Project Management |
A tree diagram is a useful method of visualizing the work breakdown structure (WBS) of a project. For the survey project, the activities are divided into three phases. In this example, the NETDRAW procedure is used to represent the work breakdown structure of the project. The following program saves the data in a Network data set that is input to PROC NETDRAW. The TREE option is used to draw the WBS structure in the form of a tree (Output 3.2.1).
