A risk owner is the individual who is accountable for the management of a specific risk. A risk owner can decide to accept a high-impact risk if the control that mitigates the risk is adversely affecting the process efficiency. However, before updating the risk register, which is a document that records and tracks the identified risks and their responses, it is most important for the risk practitioner to obtain approval from senior management. Senior management is the group of executives who have the authority and responsibility for the strategic direction and performance of the organization. Obtaining approval from senior management can help ensure that the risk acceptance decision is aligned with the organization's risk appetite and policies, and that the potential consequences of the high-impact risk are understood and accepted by the top-level decision makers. Obtaining approval from senior management can also help communicate and justify the risk acceptance decision to other stakeholders, such as regulators, auditors, customers, etc., and avoid any conflicts or misunderstandings that may arise from the risk acceptance decision.
