How and why you would use a WBS in a project?

WBS stands for Work Breakdown Structure. It is something that helps breakdown the whole projects scope into smaller and more manageable pieces. This is also a very important process in project management. To be able to actually execute the project, the project scope is broken down into manageable tasks by creating a work breakdown structure (WBS). In other Words, a WBS is a deliverable-oriented hierarchy of the work that must be performed to accomplish the objectives of and create the deliverables for the project.

WBS is one of the most important components of any Project Plan. As part of managing the project, there are many processes that are directly based on the WBS as part of the Scope Baseline. They are:

1. Cost Estimation

2. Quality Planning

3. Risk Identification

4. Procurement Planning

5. Defining Activities for Project Schedule

6. Budget Determination

So, if your WBS isnt properly created, most of your planning processes will be messed up and will be incorrect
