The work breakdown structure (WBS) is one of the most important tools you can use when managing a project.
It is simply a chart or outline of your projects deliverables. Large or complex deliverables are broken down into smaller components. The lowest level components for each deliverable are known as Work Packages.
Here's an example of a work breakdown structure...

There are some key aspects to keep in mind when you develop a WBS...
Let's take a look at why the WBS is so important for managing projects.
There are several benefits to developing a WBS for your project...
The first benefit is that all of the work to be done by the project is identified. Because of this, by reviewing the WBS with project stakeholders you will be less likely to omit any work needed to deliver the desired project results.
Second, it allows for more accurate cost and schedule estimates. Having identified the key deliverables in the Project Scope Statement, it is possible to estimate costs and schedule. But because they are at a high-level, they will be "ballpark" estimates. Breaking down each deliverable into smaller components will enable you to provide a more accurate and detailed estimate of costs and schedule.
Third, the WBS provides a basis for resource requests and task assignments. By breaking down each deliverable into distinct work packages, you will be able to determine the skill sets needed to complete the work as well as the number of people needed for each task.
Finally, a WBS will enable you to provide clear status reports on project progress since each work package is a measurable unit of work.
Having a clear picture of your project's scope is critical for it's success. A project management work breakdown structure is a key tool for bringing clarity to your project's scope and effectively managing your project.
