A risk heat map is a graphical tool that displays the risk events in a matrix based on their likelihood and impact. Risk events that are coded with the same color will have a similar risk likelihood, which is the probability or frequency of occurrence of a risk event. Risk score, riskimpact, and risk response are other possible attributes of risk events, but they are not represented by the color coding in a risk heatmap.
