Which aspect is essential for the COBIT Governance System to operate effectively?

The aspect of "Information" being essential for the COBIT Governance System to operate effectively is fundamental because COBIT emphasizes the importance of accurate and relevant information in all aspects of governance and management of enterprise IT. Information is at the core of decision-making processes, monitoring performance, and ensuring compliance with established policies and regulations.

In the context of COBIT, effective governance requires reliable information to assess how well the IT is aligned with and supports the organization's objectives. This includes data that promotes transparency, facilitates risk assessment, and guides strategic decisions. Without high-quality information, organizations would struggle to understand the impact of their IT investments, manage risks, and respond to stakeholder needs.

While resource allocation, policy enforcement, and technology infrastructure are also important for governance and management within an organization, they all depend on information. For example, effective resource allocation decisions hinge on accurate information about current usage and future needs. Policy enforcement relies on data to monitor compliance, and technology infrastructure must be effectively managed with insights gained from information analysis. Thus, without robust and timely information, the entire governance system would be impaired.
