A graphical depiction of a select number of risks analysing them in terms of probability and severity. The horizontal axis illustrates the probability of loss, high or low, while the vertical axis plots severity, high impact or low impact, two categories in each case (as in the diagram below) to give four categories. Some models use four impact categories and six probability categories. Obviously high probability/high impact losses cannot be tolerated while low probability/low impact losses can be paid out of cashflow. All risks plotted should be reviewed, controlled and financed.
