A structure (like WBS - Work Breakdown Structure or EPS - Enterprise Project Structure) is a hierarchical arrangement of the projects, items, products and services produced during and by a project.
The project is the highest level of the WBS while an individual item required to create a product or service is the lowest level.
Each project in the enterprise project structure (EPS) has its own WBS.
When creating a project, the project manager typically develops the WBS first, assigns work products and documents to each WBS element, and then defines items for performing the element’s work.
Specific earned value calculations can be specified for each WBS element, along with the Enterprise Project Structure (EPS) element responsible for all work included in the WBS element.
