When considering an IT change that would enable a potential new line of business, the first strategic step for IT governance would be to ensure agreement among the stakeholders regarding a vision for the future state, because this would provide a clear direction and purpose for the change, and align the IT strategy with the business strategy. A vision statement should describe the desired outcomes and benefits of the change, and reflect the enterprise's mission, values, and goals12.

A maturity assessment is the most appropriate method for evaluating the capability of IT governance because it helps to measure the current state of IT governance processes, identify gaps and areas for improvement, and align IT goals with business objectives. A maturity assessment can also provide a roadmap for achieving higher levels of IT governance maturity and performance. A maturity assessment can use various frameworks and models, such as the Gartner IT Score for CIOs1, the Forrester DEX Maturity Model2, the Capability Maturity Model3, or the Data Governance Maturity Model4.

The most efficient approach for using risk scenarios to evaluate a new business opportunity is to identify risk events from both bottom-up and top-down perspectives. This means that the risk identification process should consider both the specific details of the opportunity, such as the market, customer, product, service, technology, and resources involved, as well as the broader context of the opportunity, such as the strategic objectives, vision, mission, values, and culture of the organization. By using both bottom-up and top-down approaches, the risk identification process can capture a comprehensive and balanced view of the potential risks that could affect the success of the opportunity. This will help to create realistic and relevant risk scenarios that can be analyzed and evaluated for decision-making purposes. A bottom-up approach alone may miss some important risks that are related to the organization's strategy, governance, or environment, while a top-down approach alone may overlook some specific risks that are unique to the opportunity or its implementation. Therefore, a combination of both approaches is the most efficient way to use risk scenarios for evaluating a new business opportunity.
