A work breakdown structure (WBS) is a "deliverable oriented hierarchical decomposition of the work to be executed by the project team" (PMBOK). The WBS visually defines the scope into manageable chunks that a project team can understand, as each level of the WBS provides further definition and detail.

The project team creates the project WBS by identifying the major functional deliverables and subdividing those deliverables into smaller systems and sub-deliverables. These sub-deliverables are further decomposed until the specific work packages required to produce the sub- deliverable are identified.

Each work packages must be mutually exclusive (i.e. any piece of work is only identified once in one work package), and the sum of all work packages must cover 100% of the scope (i.e. if it is not in the WBS, it is not in the scope of the project).

The scope is the basis of the project. This calculates the activities, resources, cost and other areas of knowledge. That is why the use of the WBS facilitates the management of the project in a meaningful way.
