Scope Planning
The scope of work defines exactly what will be done as a result of the project work. It's important to know exactly what is to be done to avoid wasting both time and money on tasks and activities that are not necessary to accomplish the project goals. That's why scope planning is so important. This chapter will address how to define the scope of work based on the requirements of the end result and the deliverables of the project.
100 Percent Rule
The 100 percent rule is the most important criterion in developing and evaluating the WBS. The rule states that each decomposed level (child) must represent 100 percent of the work applicable to the next higher (parent) element. In other words, if each level of the WBS follows the 100 percent rule down to the activities, then we are confident that 100 percent of the activities will have been identified when we develop the project schedule. When we create the budget for our project, 100 percent of the costs or resources required will be identified.
