1.0 PURPOSE
The Work Breakdown Structure (WBS) divides the entire project into its component
elements in order to establish a framework for effective management control of the project
scope, schedule and budget.
2.0 SCOPE
The WBS is a product-oriented, hierarchical depiction of all work elements required to
accomplish the entire work scope of the project. Project Managers are responsible for the
creation of a WBS.

4.0 PROCEDURE
4.1 Structure
A project WBS is a product-oriented grouping of project work elements that organizes and
defines the total scope of the project. The WBS is a multi-level framework that organizes
and graphically displays elements representing work to be accomplished in logical
relationships. Each descending level represents an increasingly detailed definition/division
of a project component. It is the structure and code that integrates and relates all project
work (technical, schedule, and budget) and is used throughout the life cycle of a project to
identify, assign, and track specific work scopes. The WBS will be established in sufficient
detail so that each control account has a unique WBS element. The WBS is described in the
Project Execution Plan (PEP), or attached as an appendix.
4.2 Responsibility
Project Managers are responsible for the creation of a WBS for their assigned projects, with
input from other members of the project team.
4.3 WBS Dictionary
Where the title of a WBS element does not provide an adequate description of the work
involved, the project shall develop a WBS dictionary. The WBS dictionary is a set of
specific definitions that describe the scope of each work element identified in the WBS. It
defines each element to at least the control account level in terms of the content of the work
to be performed. If a WBS dictionary is not used on a project where Earned Value
Management System (EVMS) reporting is required, the project must demonstrate, to the
satisfaction of the Laboratory Project Management Officer, that the Scope of Work (SOW)
and the WBS are fully reconciled.
