Explanation:
Each project has its own WBS hierarchy with the top-level WBS element equal to
that of each enterprise project structure (EPS) node or project.
The project is the highest level of the WBS while an individual activity required to create a product
or service is the lowest level.
Each project in the enterprise project structure (EPS) has its own WBS.
Note: A WBS, or work breakdown structure, is a hierarchical arrangement of work activities that
divides a project into discrete levels, phases, or layers. The WBS is structured in levels of work
detail, beginning with the deliverable and separated into identifiable work elements.
When creating a project, the project manager typically develops the WBS first. The manager
assigns documents to each WBS element, and then defines activities to complete that element. In
addition to document and activity assignments, each WBS element can also have specific earned
value calculation settings, issue assignments, and notebook topics.
