The primary purpose of IT governance is to ensure that the use of IT generates business value and that IT investments are aligned with business strategy. Effective IT governance is ultimately measured by its outcomes, not its components. Business value and customer satisfaction are direct measures of how well IT is meeting enterprise goals and stakeholder needs. They represent the successful realization of benefits, which is a core objective of any governance framework. The other options represent important enablers or processes within governance, but they are not the ultimate evidence of its effectiveness.

A. Cost savings and human resource optimization: These are measures of resource optimization and operational efficiency. While important, they are means to an end, not the ultimate goal of strategic value creation.

C. IT risk identification and mitigation: This represents the risk optimization domain of IT governance. It is a critical function that supports value creation but is not, by itself, the best evidence of overall effectiveness.

D. Comprehensive IT policies and procedures: These are foundational enablers of a governance system. Their existence indicates a framework is in place, but it does not prove the framework is effective in delivering business value.

customer satisfaction) and cascades to enterprise goals

which are centered on benefits realization and value creation.
