The best way to prevent adverse effects to the enterprise resulting from the new technology is to develop key risk indicators (KRIs), because they are metrics that measure the potential impact and likelihood of the risks associated with the new technology, and provide early warning signals for taking corrective actions. KRIs can help the enterprise to monitor and manage the risks of integrating the new technology with the current IT infrastructure, and to ensure that the expected benefits and value are realized12.

IT governance is the process of ensuring that IT supports and enables the achievement of the enterprise's goals and objectives, and delivers value to the stakeholders1. Stakeholders are the individuals or groups that have a stake in the success or failure of IT governance, such as board members, senior management, business units, IT function, customers, suppliers, regulators, and society1. By considering stakeholders' support, an enterprise can ensure that the IT governance framework is aligned with and driven by the stakeholders' needs, expectations, and interests1. Stakeholders' support can also help to facilitate the communication, collaboration, and decision-making processes among the IT governance participants, and to gain their commitment and buy-in for the IT governance implementation and improvement1.
The other options are not as important as stakeholders' support, as they are either specific aspects or outcomes of IT governance, but not comprehensive factors. Information technology risk is the potential for negative consequences due to the use or misuse of IT within an enterprise. Information technology risk can affect the IT governance framework, but it is not the most important factor to consider, as it is only one of the many elements that influence IT governance2. Framework development cost is the amount of money and resources required to design and implement the IT governance framework. Framework development cost can affect the IT governance framework, but it is not the most important factor to consider, as it is only one of the many criteria that evaluate IT governance3. Information technology strategy is the plan that defines how the IT function supports and enables the overall business strategy and objectives of an enterprise. Information technology strategy can affect the IT governance framework, but it is not the most important factor to consider, as it is only one of the many components that constitute IT governance

According to the ISACA paper on IT Governance Reporting1, the most important benefit of effective IT governance reporting is that it helps business executives better understand IT's value contribution to the enterprise. IT governance reporting is the process of communicating relevant and reliable information about the performance, value and risk of IT to the stakeholders who are responsible for making decisions and taking actions related to IT. Effective IT governance reporting enables business executives to have a clear and comprehensive view of how IT supports and enables the achievement of the enterprise's strategy, objectives and goals. It also helps business executives to assess the alignment, efficiency and effectiveness of IT, as well as to identify and address the gaps, issues and opportunities for improvement. Effective IT governance reporting fosters trust, collaboration and accountability between business and IT, and enhances the reputation and credibility of IT within the enterprise. The other options are not as important as business executives better understanding IT's value contribution to the enterprise, as they are more related to the means or outcomes of effective IT governance reporting, rather than the benefit itself.
