Which of the following is a factor contributing to the good operation of the enterprise's governance system over IT?

The good operation of an enterprise's governance system over IT is significantly influenced by its components. In the context of IT governance, components refer to the various elements that together create a robust framework for governance. This includes organizational structures, processes, and resources necessary for effective management and oversight of IT.

Components are vital because they ensure that all parts of the governance framework work together cohesively. They provide the necessary infrastructure for the governance system, underlying policies, risk management strategies, and compliance measures. This integration is crucial for achieving alignment between IT objectives and business goals, ensuring that IT effectively supports the overall strategy of the enterprise.

In contrast, while principles, processes, and policies also play important roles in governance, components are foundational, as they encompass the entirety of what is required to ensure effective governance implementation and operation. They provide the building blocks from which governance can be executed efficiently and effectively, integrating all necessary elements for success in IT governance.
