Riskinmatriisi, also known as a risk matrix or probability-impact matrix, is a visual tool used in risk management to assess and prioritize risks. It typically consists of a grid where one axis represents the likelihood or probability of a risk occurring, and the other axis represents the impact or severity of that risk if it does occur. The grid is usually divided into different colored zones, such as green for low risk, yellow for medium risk, and red for high risk, based on the combination of probability and impact.

The purpose of a risk matrix is to provide a simple and intuitive way to understand the relative significance of various risks facing an organization, project, or activity. By plotting each identified risk on the matrix, decision-makers can quickly see which risks require the most urgent attention and resources for mitigation. Risks falling into the high-risk zone (high probability and high impact) are typically considered critical and demand immediate action. Conversely, risks in the low-risk zone may be accepted or require minimal monitoring.

The development of a risk matrix involves defining the scales for both probability and impact. Probability scales might range from "rare" to "very likely," while impact scales could range from "insignificant" to "catastrophic." The specific definitions for these scales are tailored to the context of the risk being assessed. While risk matrices are valuable for their clarity and ease of use, it's important to acknowledge their inherent subjectivity and the potential for oversimplification. The quantitative accuracy of a risk matrix is limited, and it should be used in conjunction with other risk assessment techniques for a comprehensive understanding of potential risks.
