The Work Breakdown Structure (WBS)
•Used as a basis for a number of processes in
particular to produce the subsidiary plans of the
Project Management Plan.
•The WBS is a deliverable-oriented hierarchy of
decomposed project components that organises
and defines the total scope of the project. The WBS
is a representation of the detailed project scope
statement that specifies the work to be
accomplished by the project.
•The elements comprising the WBS assist the
stakeholders in viewing the end product of the
project.
•The work at the lowest-level WBS component is
estimated, scheduled, and tracked.

The Dictionary of the WBS
•A WBS dictionary is a companion document to the
WBS that describes each WBS element. For each WBS
element, the WBS dictionary includes a statement of
work, a list of associated activities, and a list of
milestones.
•Other information can include the responsible
organisation, start and end dates, resources required,
an estimate of cost, charge number, contract
information, quality requirements, and technical
references.
•WBS elements should be cross-referenced as
appropriate.

Developing the WBS
•Divide the total work of the project into
major groups...
•...then subdivide these groups into
tasks...
•...then divide these tasks into sub-tasks
•Subtasks should be small enough to
permit adequate control and visibility
•But avoid excess bureaucracy!

“Scope Breakdown Structure”
(Max Wideman’s approach)
•Geographically discrete components
•Time based phases and stages
•Intermediate or final major deliverables
•Discrete structural, process, system or device
components
•Deliverable elements that can be associated
with distinctive types of people-skills or
resources
•After that, break down the work as in the WBS

Summary
•The WBS is used to define the
activities that are then further
managed.
•Consider alternatives:
Work Breakdown Structure
Product Breakdown Structure
Scope Breakdown Structure
•Use Common Sense in Breakdown the
Project.
