The P3O® Foundation (2013) manual identifies reporting portfolio performance through management dashboards as a delivery support function. Section 7.2.1 states, "Delivery support functions include reporting portfolio performance using management dashboards to provide real-time insights to stakeholders." This differs from training (B), resource provision (C), or process development (D), which are capacity or strategic functions. The 2013 edition emphasizes this reporting role to support ongoing project and programme delivery, ensuring visibility and control. This enhances operational effectiveness.
