Where should an Organization Portfolio Office ultimately report?

The P3O® Foundation (2013) manual specifies that the Organization Portfolio Office (OPO) should ultimately report to a main board director. Section 5.3.2 states, "The Organization Portfolio Office should report to a main board director to ensure strategic alignment and direct accountability at the highest level." This differs from corporate services (B), Programme Manager (C), or Head of P3O (D), which are lower or supportive levels. The 2013 edition emphasizes this reporting line to integrate portfolio oversight with corporate governance, ensuring strategic influence. This structure supports effective decision-making and resource allocation.
