Which of the following BEST enables an enterprise to maximize value from the use of I&T?

Maximizing value from I&T is the primary objective of governance. This is achieved by balancing three key outcomes: benefits realization, risk optimization, and resource optimization. An actionable strategy, supported by a comprehensive governance system, provides the direction and mechanisms to achieve this balance. The governance system ensures that I&T investments are aligned with enterprise goals and that performance is managed to deliver the expected value. The other options are components of a governance system, but this option represents the overarching enabler.

A. Well-documented processes are a component (an enabler) of a governance system, but they alone do not ensure value maximization without an overarching strategy.
B. A defined management structure is also just one component of a holistic governance system; it cannot maximize value in isolation.
