1/1

The Project Management Body of Knowledge (PMBOK) defines thework breakdown

structureas a deliverable oriented hierarchical decomposition of theworkto be executed

by the project team. Division of the main work into smaller works depending upon the

importance or level of work. Each activity is given a unique number like heading numbers in

a thesis and is further divided into sub headings and the numbering is continued. A typicalexample of a work breakdown structure is shown in the following image. The lowest level

works of a WBS are called work packages. WBS are very much important in planning. All

planing engineers should be familiar with the WBS techniques and One of the technique is

100% rule. Here we have included two examples related to WBS and one can find a lot of

other examples as well .The first example illustrates the different levels of a WBS with

numberings, just to get an idea how one can make his projects WBS.

100% Rule

An important design principle for work breakdown structures is called the 100% rule.
