Which is a functional area within a P3O model?

COE (Centre of Excellence) functions or services are a functional area within a P3O model, per the P3O® Foundation (2013) manual. Section 5.3.4 states, "The Centre of Excellence provides a functional area within the P3O, offering standards, guidance, and best practices to support PPM maturity." This contrasts with Hub Portfolio Offices (A), which are structural models, Virtual Offices (C), which are temporary setups, and Flexible Resource Pools (D), which are resource mechanisms. The 2013 edition highlights the COE’s role in standardizing processes, making it a core P3O component. This ensures consistent support across the organization.
