Begin Implementation of New IT Governance Model

C.

The implementation of a new IT governance model is a significant undertaking for any enterprise. The implementation process should begin by identifying the role of IT in supporting the business, which is the BEST way to begin.

Option A, prioritizing how much and where to invest in IT, is not the best way to start the implementation process because investment decisions are based on a clear understanding of the organization's IT goals and objectives, which are defined through the IT governance model.

Option C, defining policies for data, applications, and organization of infrastructure, is an important part of the implementation process, but it is not the best way to start. Defining policies can be a complex process that requires input from various stakeholders and is typically based on a clear understanding of the role of IT in supporting the business.

Option D, identifying IT services that currently support the enterprise's capability, is an important step in the implementation process, but it does not provide a comprehensive understanding of the role of IT in supporting the business. A more strategic approach is required to develop an effective IT governance model.

Therefore, the BEST way to begin the implementation of a new IT governance model is to identify the role of IT in supporting the business. This involves a comprehensive analysis of the enterprise's business objectives, identifying the IT capabilities required to support those objectives, and defining how IT will deliver those capabilities.

This approach will ensure that the new IT governance model is aligned with the enterprise's business objectives, and that IT is able to deliver the capabilities required to support those objectives.
