1. One PMO can hide another...

If the PMO is assigned to a project on a part-time basis, he/she is expected to add value to the project, but has a degree of independence in the choice and implementation of project methods, as he/she receives instructions from his/her business manager in the Project Management Office.

The integrated PMO, assigned full time to a project, is much more influenced by the project manager, who is the final recipient of its deliverables.

This PMO, or rather these PMOs (generalist PMO, risk manager, planner, etc.) report directly to the project manager and are assigned 100% of their time to the project.
