To create a work breakdown structure (WBS) is:
- The process of breaking down project deliverables and project work into smaller, more manageable components.
- The main function of this process is to provide a framework for the content to be delivered.
WBS is:
- A hierarchical breakdown of the entire scope of work that the project team needs to implement in order to achieve the project goals and create the required deliverables.
- The lowest part of the WBS is called the work package. The work package categorizes related work in order to schedule, estimate, monitor and control the work.
The organizational process assets that can affect the process of creating WBS include:
- Policies, procedures and templates used to create WBS
- Project files of past projects
- Lessons learned from previous projects
The decomposition is:
- A technology that gradually divides the project scope and project deliverables into smaller and more manageable components
- Work package is the lowest level work of WBS, its cost and duration can be estimated and managed
- The degree of decomposition depends on the degree of control required
- The level of detail of the work package varies depending on the size and complexity of the project
To decompose the entire project work into work packages, the following activities are usually required:
- Identify and analyze deliverables and related work
- Determine the structure and layout method of WBS
- Refine and decompose layer by layer from top to bottom
- Develop and assign identification codes for WBS components
- Verify that the degree of decomposition of deliverables is appropriate
Rolling plan
100% rule
The scope benchmark is:
- Approved scope statement, WBS and corresponding WBS dictionary
- Changes can only be made through formal change control procedures, which are used as a basis for comparison
The scope baseline is an integral part of the project management plan and includes:
- Project scope statement
- WBS
- Work package
- Planning package
- WBS dictionary
