A risk heat map is a visualization tool that shows the likelihood and impact of different risks on a matrix, using colors to indicate the level of risk. A risk heat map can help prioritize the risks that need the most attention and resources, and support the decision making and planning process for risk management. Mapping open risk issues to an enterprise risk heat map best facilitates risk response, which is the process of selecting and implementing the appropriate actions to address the risks. Risk response can include strategies such as mitigating, transferring, avoiding, or accepting risks. By mapping open risk issues to a risk heat map, an organization can identify the most suitable risk response for each risk, based on the risk appetite, criteria, and objectives. A risk heat map can also help evaluate the effectiveness and efficiency of the risk response, by showing the change in the level of residual risk after the risk response has been executed. References = What Is a Risk Heat Map & How Can It Help Your Risk Management Strategy, What Is a Risk Heat Map, and How Can It Help Your Risk Management Strategy, Risk Map (Risk Heat Map), How To Use A Risk Heat Map.
