The P3O® Foundation (2013) manual indicates that a Portfolio Office requires staff skilled in interpreting and challenging data. Section 3.5.3 states, "The Portfolio Office should be staffed with individuals capable of interpreting complex data, challenging assumptions, and providing analytical support to inform portfolio decisions." This contrasts with aspirations for project management (A), identical COE skills (B), or heavy administrative staffing (D), which do not align with the analytical focus. The 2013 edition emphasizes the need for analytical expertise to support portfolio prioritization and risk management, ensuring strategic decision-making. This skill set is critical for the Portfolio Office’s role in providing high-level support and insights.
