What is WBS decomposition?

Wbs decomposition, commonly known as work breakdown structure method, is a decomposition method that divides a large project into multiple small tasks according to principles, breaks down each small task into specific tasks, and then divides the work into each person's work.

As shown in the figure below, taking the opening of a KTV as an example, the project is to open a store. The small tasks are broken down into five parts: project initiation, editing task plans, project construction, publicity and promotion, and staff recruitment. Collecting data, creating a WBS, and other specific tasks are specific tasks. If the specific work is not detailed enough, it can be further explained in more detail.


The value of WBS decomposition

1) Control the overall project progress

The entire chart is broken down into multiple modules, which can clearly organize the structure of the entire project. Based on the detailed work, it can better clarify the current progress of the project and which work has an impact on the work progress.

2) Clarify the scope of personnel's work

In every task or job, there is a clear person in charge who can clarify their work goals and scope, focus on their own goals, and avoid situations where no one is doing the work.

3) Estimated project cost

The project is subdivided into small tasks, making it easier and more accurate to plan, budget, work time, duration, and required resources for each small task. So as to achieve better and more accurate budgeting for the project.

How to draw WBS decomposition?

Having learned the basic knowledge of WBS decomposition above, we will use the Yitu diagram to learn how to draw a WBS decomposition diagram. Yitu diagrams are available in both online and client versions and can be saved on a synchronous cloud drive.

The following is an online version of the Yitu diagram to demonstrate the drawing steps:

Step 1: Open the Yitu diagram in the browser and open a new canvas

Open the Yitu diagram, find "Business Project Management WBS Diagram", and click on "Create Template". You can create a blank canvas or an existing template, using an existing template as an example.

Step 2: Modify the template layout and beautify it

Now that you have a template, modify the existing template according to your project layout. Place the mouse over the border and a new plus sign will appear. Clicking on the plus sign will create a new box in the corresponding direction, so that you can modify it to the layout you need. Click on the toolbar to beautify and modify color combinations.




Step 3: Add text information

Double click in the middle of the box to add the required text. Here, modify the corresponding text according to your own file.

Step 4: Save the file

Click on the file in the menu bar to save the file, which can be exported to common formats such as images, tables, Word, PDF, etc., or choose to save to cloud storage and print.
