Which is a COE function or service?

The P3O® Foundation (2013) manual identifies supporting PPM tools as a COE function. Section 5.3.4 states, "The Centre of Excellence (COE) provides functions such as supporting PPM tools to ensure consistency and maturity in project, programme, and portfolio management." This differs from programme delivery (B), capacity planning (C), or strategic alignment (D), which are handled by other offices. The 2013 edition emphasizes the COE’s role in standardizing tool usage, enhancing organizational PPM capability. This supports consistent practice across the P3O model.
