What is A Work Breakdown Structure (WBS)
The Project Management Body of Knowledge (PMBOK) defines the work breakdown structure as a “deliverable oriented hierarchical decomposition of the work to 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 typical example 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 project’s WBS.
An important design principle for work breakdown structures is called the 100% rule. Read More Here
