Product breakdown structure

Product breakdown structure

In project management, a product breakdown structure (PBS) is an exhaustive, hierarchical tree structure of components that make up an item, arranged in whole-part relationship.

A PBS can help clarify what is to be delivered by the project and can help build a work breakdown structure.

The PRINCE2 project management method mandates the use of product based planning, part of which is developing a product breakdown structure.
