The process of breaking down project deliverables and project work into smaller, more manageable components

It is the basis of project management. All planning and control work of the project must be based on the work breakdown structure

Read it once and understand it

（1） Make the project clear to project stakeholders

（2） Ensure the systematicness and integrity of the project structure

（3） Can establish a complete project guarantee system

（4） Clarify the working interface of all parties involved in the project to facilitate the division and implementation of responsibilities

（5） The final WBS can be directly used as a tool for schedule planning and control

（6） Provide a basis for establishing project communication management and facilitate grasping the key points of information

（7） It is the basis and main basis for the formulation of each sub-plan and control measures of the project.

（8） Helps prevent requirements and scope creep

1. All work of the project must be included in the WBS, and any work not included in the WBS is not part of the project and cannot be done, otherwise it will be "gold-plated"

2. The preparation of WBS requires the participation of all project stakeholders and the participation of project team members.

3. WBS is decomposed layer by layer. The decomposition level of each branch does not have to be equal. Generally, it should be controlled at 3 to 6 layers.

4. Each element in the WBS should be relatively independent and overlap with each other should be minimized.

The process of formal acceptance of completed project deliverables

Deliverables and work products need to be reviewed to ensure that all work on the project is completed accurately and satisfactorily

throughout the project

The scope validation process should document its completion in a written document

When the scope of confirmation is completed, the WBS and WBS dictionary adjusted during the confirmation should be updated.

1||| Determine when scope needs to be confirmed

2||| Identify what inputs are needed to validate the scope

3||| Determine the formally accepted criteria and elements for scoping

4||| Determine the organizational steps for a scope meeting

5||| Organize scope confirmation meeting

Control quality process

The control quality process usually precedes the validation scope process, But both can also be done at the same time
