To support the 'govern effectively' principle, a P3O provides independent gated review coordination and assurance, as per the P3O® Foundation (2013) manual. Section 7.3.2 notes, "P3O supports effective governance through independent gated reviews and assurance processes to ensure compliance and quality across change initiatives." This involves objective oversight, unlike coaching/training (A), benefits tracking (C), or fast-track mobilization (D), which serve different purposes (e.g., capacity building or delivery support). The 2013 edition underscores this assurance role as critical for maintaining governance standards, enabling senior management to monitor progress and mitigate risks. This aligns with the P3O’s function of providing a robust control framework, ensuring strategic alignment and accountability throughout the change lifecycle.
