The P3O® Foundation (2013) manual identifies that the portfolio prioritization and optimization technique supports senior management investment decisions by aligning programmes with strategy. Section 6.3.1 states, "This technique supports senior management by prioritizing and optimizing the portfolio to align programmes and projects with strategic objectives, aiding investment decisions." This differs from highlighting issues (A), documenting processes (B), or providing capacity (C), which are secondary outcomes. The 2013 edition emphasizes its strategic decision-making role, ensuring resources focus on high-value initiatives. This enhances portfolio effectiveness.
