A responsive risk awareness culture is the best reflection of mature risk management in an enterprise, because it implies that the organization has a high level of risk maturity that enables it to reduce noise and focus more effectively on truly high-risk concerns, choose cost-effective solutions for the risk management priorities, and execute reliably1. A responsive risk awareness culture also means that the organization has a clear and consistent risk appetite and tolerance, and that the employees are cognizant of the relevant risks as part of their actions2. A responsive risk awareness culture also fosters trust, collaboration, and innovation among the stakeholders, and helps the organization to adapt to changing business environments and emerging risks3.

The other options are not as indicative of mature risk management in an enterprise, because they are either too narrow or too reactive. A regularly updated risk register is a useful tool forcataloguing, tracking, and mitigating risks, but it does not necessarily reflect the strategic alignment, integration, or performance of the risk management process4. Ongoing risk assessment is an essential activity for identifying and evaluating risks, but it does not guarantee that the risks are prioritized, communicated, or managed effectively5. Ongoing investment in risk mitigation is a sign of commitment to risk management, but it does not ensure that the investment is aligned with the risk appetite and tolerance, or that it delivers value to the organization5.
