Which of the following best describes a Data Governance maturity model?

A Data Governance maturity model serves as a framework for evaluating data handling practices within an organization. It provides a structured approach to assess how well an organization manages its data and can highlight areas of strength and opportunities for improvement in data governance.

By using this model, organizations can track their progress in establishing effective data governance policies, processes, and responsibilities. It typically categorizes the development of data governance on a scale that ranges from initial or ad hoc practices to fully optimized and integrated governance frameworks. This insight is crucial for organizations that aim to enhance their data management capabilities.

In contrast, the other options do not accurately represent the concept of a Data Governance maturity model. While software tools may aid in governance, they do not constitute a model for evaluating practices themselves. A checklist for IT infrastructure relates more to hardware and software compliance rather than governance assessment. Lastly, a plan for upgrading hardware focuses on physical technology rather than the overarching governance structure which the maturity model aims to assess and refine.
