What Is a Work Breakdown Structure (WBS)?
A work breakdown structure (WBS) is a visual, hierarchical, deliverable-oriented project teardown. It is a useful diagram for project managers because it allows them to break down the scope of their projects and visualize all of the tasks required to execute them.
The work breakdown structure chart outlines all project work processes, making it a vital project planning tool. The ultimate project deliverable, as well as the tasks and work packages connected with it, are placed on top of the WBS diagram, and the WBS levels below partition the project scope to represent the tasks, deliverables, and work packages required to complete the project from beginning to end.
