Create a work breakdown structure

The work breakdown structure (WBS) is a layered breakdown of deliverables-oriented project elements, which organizes and defines the project management.
The work breakdown structure is generally expressed in charts. It is a specific manifestation of the work breakdown structure and a list of all activities required to implement the project and implement the final product or service, it is also the basis of the progress plan, personnel allocation, and budget plan.
Currently, the commonly used work breakdown structure is represented in the following two forms:
The hierarchical tree structure is similar to the organizational structure.
A table is similar to a hierarchical library directory.

Input for creating a work breakdown structure
(1) Project Scope Statement (detailed)
(2) project management plan

2. Decomposition
Decomposition refers to dividing major project deliverables into smaller and easier-to-manage units until deliverables are subdivided into toolkits that are sufficient to support future project activity definitions.
Decomposition steps:
Main Components of the identification and validation Project
Break down and confirm whether each component is detailed enough
Validation of components of key deliverables of the project
Verify the correctness of the decomposition

Principles to be grasped for working structure decomposition:
Maintain project integrity at all levels to avoid missing necessary components.
A work unit can only belong to a certain upper-level unit to avoid cross-subordination.
Work Unit applications of the same level are of the same nature.
The work unit should be able to separate different persons in charge and different work content.
This facilitates project management planning and control management.
The work at the lowest layer should be comparable, manageable, and quantifiable.
Project management should be included (as part of the specific work of the project), including subcontracting.
