Nonlinear intervals for probability and impact
In standard risk impact and probability matrixes, intervals can be non-linear. For example, in some 5x5 risk matrixes, Very High probability often indicates a probability of 100 - 70%, High 70 -50%, Moderate 50-30 %, Low 30-20% and Very Low is >10%. The risk matrix can be setup so that the matrix “intervals” can be modified so that each interval can represent a different scale for both probability and impact. Sum of all intervals must be equal 100%. If tthe sum is not equal to 100%, the background color will be switched from green to pink.
The same process can be used to customize your impact matrix:
