A WBS is a hierarchy of work that must be accomplished to complete a project, which defines a product or service to be produced. The WBS is structured in levels of work detail, beginning with the deliverable itself, and is then separated into identifiable work elements.
Each project has its own WBS hierarchy with the top level WBS element being equal to that of each EPS node or project. Each WBS element may contain more detailed WBS levels, activities, or both.
When creating a project, the project manager typically develops the WBS first, assigns documents to each WBS element, and then defines activities for performing the element's work. In addition to document and activity assignments, each WBS element also has an assigned calendar, specific earned value calculation settings, and an assigned OBS element responsible for all work included in the WBS element.
