Deep dives
Origins and Evolution of Risk Matrices
Risk matrices originated from early insurance and decision science as mathematical tools used to calculate expected values based on frequency and likelihood. These tools have evolved into simplified tables that categorize severity of consequences against likelihood of outcomes, typically represented in colors to indicate risk levels. The primary function of modern risk matrices is to prioritize risks based on assessed severity and likelihood; however, the debate continues on whether they truly serve as decision-making tools or merely act as communication aids. Even as risk matrices are increasingly required by standards and regulations, their effectiveness in enhancing decision quality remains contentious.
