## 1. Purpose of the PMO Reference Layer

In modern value-delivery systems, the **Project/Program/Portfolio Management Office (PMO)** acts as the critical engine of project governance, standard enablement, capability improvement, and strategic alignment. This reference layer bridges the high-level governance guidelines in the **PMBOK 8th Edition** with the highly granular, execution-oriented standards in the **PMI PMO Practice Guide**.
