Organizational breakdown structure (OBS) overview

The organizational breakdown structure (OBS) is a global hierarchy that represents the managers responsible for the projects in your enterprise. The OBS usually reflects the management structure of your organization, from top-level personnel down through the various levels constituting your business. You can associate the responsible managers with their areas of the EPS (Enterprise Project Structure) — either nodes or individual projects. When you associate a responsible manager with an EPS node, any projects you add to that branch of the EPS are assigned that manager element by default.

The OBS hierarchy is also used to grant users specific access privileges to projects and the WBS (work breakdown structure) levels within projects.
