In most textbooks and publications, WBS basically appears in the form of an organizational structure diagram, which clearly shows the structural characteristics of WBS. However, unfortunately, it cannot show all the meanings of WBS. How is the full connotation of WBS reflected?First, let's look at the definition of PMI
Principles of WBS decomposition:
The principle means that WBS cannot break down items or contain any products or activities out of the scope of the project.
Vertical refers to whether the WBS decomposition should be fine enough to meet the task allocation, detection and control purposes.
WBS decomposition method:

The following is the WBS of a widely spread software project on the Internet. I believe many people have created similar WBS.
It is because of our ancestors, the ancestors of the ancestors with similar methods to Create WBS, ears and ears, we also developed the same habit.
This is a typical problematic WBS.
First,
With the continuous promotion and widespread acceptance of project management technology, WBS has gradually entered the project manager's vision, one of the core tools for daily project management, it fully embodies the core concept of "decomposition" of PMBOK, which can help the project team to control the overall situation and avoid project deviation due to lack of weeks or lack of experience, even fall into the abyss of failure. Here, I will sort o
Since there is no WBS, it becomes the core of the project manager to manage the project without project management. Every company with mature project management has a certain WBS template for different types of projects for the project manager's reference. For complex and large projects, the WBS production process recommended by IBM is as follows:
1. Create

Although the current telephone system is digital, it still inherits the same bandwidth as the traditional analog system. From the point
disadvantage, because everyone knows that joining a new person in the project will only affect the progress)
In the early stage of the project, as an ordinary employee, what should I do most in this case? I think the most important thing is to make a good personal plan.It is not an overall plan starting from project management, but a personal plan for your own task (Function Point)-WBS list:
The project plans formulated by the Project Manager are
After thinking about this problem for a while, the conclusion is ridiculous. That is, all the previous WBS reference books are very simple to use due to space limitations. These simple projects can quickly see deliverables and activities, so they are all done at once.
Let's make a comparison. The garage project is based on the deliverables as follows:
The activity-based method is as follows:
The former emphasizes what we want to do, and
A work breakdown structure (WBS) is the process of progressively dividing project deliverables and project work into smaller, more manageable project units that organize and define the entire project scope. The lowest level elements of a WBS are those that can be evaluated, scheduled, and tracked. It is the main basis of organizational management work.There are two main types of work breakdown structures:⊙
