Summary
The Project Breakdown Structure is a tree structure reflecting the
Work Products on all levels produced by a project.
The Project Breakdown Structure should contain all the items
included in the final product, needed to build the final product and
needed to support the development of the final product.
The Work Breakdown Structure is later identified by defining what
activities are needed to produce the Work Products to the required
quality.
