The WBS (work breakdown structure) is a process used in project management to identify the scope of a project and all the associated tasks that must be done to complete the project as defined. For this purpose, a results-oriented hierarchical decomposition of the work is carried out. This technology not only makes the work more accessible and manageable. It also enables the monitoring of different processes of a project, the estimation of costs and schedules and helps with team building. This led to WBS becoming one of the most important project management tools.
In the following, the author presents the different structuring techniques of a work breakdown structure. Furthermore, he describes the process of creating a work breakdown structure, the different forms of presentation as well as the advantages and limitations of a work breakdown structure and will illustrate these with examples.
