An enterprise wants to implement metrics to monitor the performance of its IT portfolio.

IT portfolio performance metrics must reflect the value delivered to the business, making business unit stakeholders’ input critical. The CGEIT Review Manual 8th Edition emphasizes that business stakeholders are the primary source for defining metrics that align with business objectives.

Extract from CGEIT Review Manual 8th Edition (Domain 5: Benefits Realization):"When establishing metrics to monitor IT portfolio performance, the input of business unit stakeholders is most important, as they define the business objectives and value expectations that the IT portfolio must deliver." (Approximate reference: Domain 5, Section on Performance Metrics)

Considering the input of business unit stakeholders (option D) ensures that metrics measure outcomes that matter to the business, such as revenue growth, customer satisfaction, or operational efficiency.

Why not the other options?

A. Project management office (PMO): The PMO focuses on project execution, not business value definition.

B. IT executives: IT executives provide technical input, but business stakeholders define value.

C. The chief executive officer (CEO): The CEO may set high-level goals, but business units provide detailed requirements.
