Project Management Work Breakdown Structure
April 19, 2009 Leave a comment
Work breakdown structure (WBS): The deliverable-oriented hierarchical decomposition of the total scope work to be executed by the project team to accomplish the project objectives and create the required deliverables.
WBS purpose: Organizes and defines activities (the total scope of the project.)
WBS Component: An entry in the work breakdown structure that can be at any level
WBS dictionary: The artifact that provides detailed deliverable, activity and scheduling information about each component in the WBS to support the WBS.
Examples of what could be in the WBS Dictionary:
- A code of account identifier
- Description of work
- Assumptions & constraints
- Responsible organization
- Cost Estimates
- Quality requirements
- Acceptance criteria
- Technical references
- Agreement information
Work Package: The work defined at the lowest level of the work breakdown structure for which cost and duration can be estimated and managed
Steps before beginning the WBS:
- Obtain charter approval
- Define the project requirements
- Form the core team
- Ask the team to list all work packages under their responsibilities so they can be combined to make the WBS.
