WBS is the "Work Breakdown Structure" already used mainly to check the project flow by identifying "Tasks, Resources, Milestones, Activities, Activity duration, etc.". The WBS help with apply dependencies as we define the predecessor and successors for each task and this will help us to understand and analyze when our project will start and when it's end, from the tasks perspective. After that we can list all the stakeholders who will be engaging on the project to ensure we are aligned and keep the project on track. Today's tools will assist the teams in understanding the project flow, how well the activities are progressing, and where the bottlenecks lie in the project, in order to apply the corrective actions appropriately.

It's important to realize that there isn't a single way to break down the project, and that the project type, industry, or project size can influence how you decide to break the WBS into lower levels. For instance, on a large construction project, you may want to break the WBS down by construction phase. Or on a large multi-site consulting project, you may want to break it down by geographic region. Or on a highly technical manufacturing prototype, you may want to break it down by major components and then subcomponents. Before you create your full-blown WBS, think through the pros and cons of organizing it in different ways.

As a project manager, one needs to first know the objective of the project and come up with smaller tasks whose output yields the objective of that project. WBS by definition involves you breaking down a project into manageable tasks / portions that have a responsible "person" as well as the sequencing of these tasks. At the point of breaking them down, a PM must involve all stake holders so that all the objectives of the project are not missed. And by doing this, a PM can build the scope based on the tasks and by having them clearly defined, he/she will avoid scope creep. A good WBS can be a tool for resource allocation, risk mitigation as well as a "check list"

A good WBS helps with ensuring that you as a Project Manager is effective and Efficient. (This is in form of results and timelines) It also helps in managing scope creep. WBS helps you as a PM to mitigate risks which could be in terms of resources I would use WBS to enhance collaboration among stakeholders

A well defined WBS helps the Project Manager to identify potential risks and mitigate them before hand. It ensures that all departments and people involved are well aware of their tasks, and assign resources as needed.

Understand clearly the objectives of the project Related tasks could be assigned to the same person When sequencing, a task MUST always yield the next task During implementation, start with smaller tasks that do not require a lot of resources to accomplish
