The P3O® Foundation (2013) manual describes the Portfolio Office’s focus as ensuring investment in the right programmes. Section 5.3.2 states, "The Portfolio Office focuses on ensuring that investment is directed toward the right programmes by aligning them with strategic objectives and optimizing the portfolio." This differs from implementation (A), programme support (B), or standard definition (C), which are programme or COE roles. The 2013 edition emphasizes this strategic investment role to maximize value, supporting P3O’s governance function. This ensures resource allocation aligns with organizational priorities.
