7. Work Breakdown Structure
7.4 WBS- A Mandatory Management Tool
h) Characteristics of a High-Quality WBS
a) Review and signoff from top to bottom
b) Includes logical flow and is hierarchical in nature
c) Clear and concise
d) Provides ability to roll-up information to higher levels
e) Receives 100% team buy-in
f) Should have at least 2 levels: Level 1 defines 100% of the service/product/result; Level 2 defines the deliverables in terms of work (groupings)
g) Project Management (and sub-contract management) at Level 2.
h) The deliverables in the WBS must match the scope or contract (WBS should not contain work that is not defined in the scope – Scope should not describe work not contained in the WBS)
i) All deliverables should be accounted for regardless of responsibility
j) Every WBS element should be clearly defined – or should be clarified in the WBS Dictionary
k) Features
- The WBS should contains 100% of the work defined by the scope or contract
- Development of WBS should involve the entire project team
- Should be deliverable-oriented
- Should captures all deliverables (Internal, External, Interim) in terms of work to be completed
l) Usefulness

- Should define the context of the project and clarifies the work
- Should communicates project scope to all stakeholders in terms of the work to be completed
- Is “in sync” with the scope statement and project schedule
- Implies and allows for continual improvement/update of the WBS to maintain current-ness and “vitality” within the project
m) WBS Is Not
- A single document that substitutes for the project schedule or project plan
- The project schedule
- A listing of tasks or activities
i) Types of WBS
The two types of Work Breakdown Structures are:
a) Program Work Breakdown Structures
b) Contract Work Breakdown Structures
a) Contract WBS
A Contract WBS extends the Program WBS to a lower level in order to provide management and cost information to the Government. It includes all the elements for products (e.g., hardware, software, data, or services) that are the responsibility of the contractor. It must be consistent with the Program WBS.

Typically, a Program WBS consists of the upper three levels.
WBS Level 1: The entire defense materiel item.
WBS Level 2: Major elements of the defense materiel item, which are subordinate to Level 1.
WBS Level 3: Elements subordinate to Level 2 elements.
