What Is the PBS?
The PBS is a hierarchical decomposition of work products into components. The PBS focuses on what must be produced and is required to create the WBS, which focuses on how to produce the work product. Each level of the PBS represents an increasingly detailed view of the components.
There is a Worldwide Project Management Method (WWPMM) work product description and a template that assists you with the creation of the PBS work product. You can find this information and descriptions and templates for all WWPMM work products at the following Web address:
