Which of the following would BEST help assess the effectiveness of a newly established IT governance framework?

Developing a business case for a program portfolio is a planning activity for investments, not an assessment of an existing governance framework's effectiveness.

Evaluating Key Performance Indicator (KPI) results provides objective and measurable data on how well the IT governance framework is achieving its stated objectives, such as improved IT service delivery, risk management, or resource optimization. KPIs allow for concrete assessment of the framework's operational effectiveness and its impact on the business.

Benchmarking to industry best practices can provide context and identify areas for improvement, but it does not directly measure the effectiveness of the *currently established* framework within the specific enterprise.

Reviewing results of IT audit reports can identify compliance gaps or control weaknesses, which contributes to governance, but it provides a point-in-time check rather than a comprehensive, continuous assessment of the framework's overall effectiveness in meeting its objectives.
