Primavera Tip: OBS and EPS - Things to Keep in Mind When Creating It
The Organizational Breakdown Structure (OBS) is a hierarchical based
structure that represents your organization. The Enterprise Project
Structure (EPS) is also a hierarchical based structure that represents
how your projects are organized.
The OBS and EPS are combined together through the responsible manager
field on the EPS structure, project folder and WBS level. The
Responsible Manager field is the OBS and this determines what users can
gain access to the Project. When you create a user, you have to give
them Responsible Manager assignments in order for them to see projects.
Your EPS and your OBS need to have a one-to-one relationship. If you
give a user a Responsible Manager assignment (OBS) that is not tied to
an EPS, Project or WBS level, they will not see any projects when they
log into the Primavera Client application or the Web Application.
