An enterprise has committed to the implementation of a new IT governance model. The BEST way to begin this implementation is to:

Identifying current IT services is an operational assessment, which is important, but it should follow the strategic definition of IT's role to ensure those services align with the overarching business objectives.

Defining policies for data, applications, and infrastructure is a tactical step in implementing governance controls, which should be guided by the broader strategic role of IT identified beforehand.

Before establishing specific services, policies, or investment priorities, it is crucial to understand and articulate how IT aligns with and contributes to the enterprise's strategic goals and objectives. This foundational understanding ensures that all subsequent governance activities are directly geared towards supporting the business mission, making IT a strategic partner rather than just a cost center.

Prioritizing IT investments is a key outcome of effective IT governance, but it relies on a clear understanding of IT's strategic role and how those investments will contribute to business value.
