CORE DEFINITION

A matrix tool that uses two dimensions, 'consequence severity' and 'probability of occurrence', to classify risks into different levels (e.g., low, medium, high, extreme).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Risk prioritization. Resources are limited; we cannot prevent all risks. It is necessary to prioritize risks with 'high probability + high severity' (top right corner), while risks with 'low probability + low severity' can be accepted or monitored.

The risk matrix forms a two-dimensional grid with 'probability of occurrence' and 'consequence severity' as axes, positioning each risk in the corresponding cell and grading by color. It compresses multi-dimensional uncertainty into a single priority signal, assuming that risks can be sufficiently ordered by these two dimensions. Underlying it is a qualitative approximation of expected loss—a rank ordering of probability times severity.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

First, determine the scales for probability and severity (e.g., 1-5 levels) and the classification thresholds. Score each identified risk and place it in the grid. Then prioritize by color (red/yellow/green), developing responses for red zone risks, monitoring or accepting green zone risks, and regularly reviewing and updating scores.
