Understanding a risk matrix table involves interpreting the information presented in the matrix to understand the potential risks and their levels of significance. A risk score matrix typically consists of two main axes: one representing the likelihood of a risk occurrence, and the other representing the impact or consequence of that risk. Each cell in the matrix corresponds to a combination of likelihood and impact and is associated with a risk level or rating. Here’s a step-by-step guide on how to read a risk assessment matrix table:

Identify the Axes: Understand the two axes of the risk matrix. The horizontal axis usually represents the likelihood, while the vertical axis represents the impact. These axes are divided into discrete levels or categories.

Axis Categories: Examine the categories on each axis. The categories for likelihood and impact can vary but commonly include descriptors such as “Low,” “Medium,” and “High” or numerical values like 1 to 5.

Cell Values: Each cell in the matrix corresponds to a specific combination of likelihood and impact. The intersection of a likelihood category and an impact category is where you find the risk level or rating associated with that combination.

Risk Levels: Different organizations may use various terms for risk levels, such as “Low,” “Medium,” and “High,” or numerical scales like 1 to 5. Understand the meaning of each level in the context of your risk management matrix table.

Color Coding: Many risk matrices use color coding to highlight the risk levels visually. For example, cells representing higher risk levels may be colored in red, while lower risk levels may be in green. Check the legend to understand the color-coding scheme.

Assessing Risks: Look at the specific cells where the likelihood and impact intersect. These cells provide information about the risk associated with a particular scenario. Higher risk levels generally indicate scenarios that require more attention and mitigation efforts.

Prioritization: Identify areas in the matrix where the risks are concentrated. These areas represent scenarios with higher potential impact and likelihood and should be prioritized for risk management actions.

Understanding Residual Risk: Some risk matrices also include a concept of residual risk. Residual risk is the risk that remains after implementing risk mitigation measures. The matrix may have a separate set of values or colors to represent the residual risk levels.

Updating the Matrix: Risk matrices are dynamic tools, and it’s essential to update them regularly. As new information becomes available or the risk landscape changes, adjust the likelihood and impact assessments to ensure the matrix reflects the current state of risks.

Using Supporting Information: Some risk matrices may include additional information, such as recommended actions, descriptions of specific risks, or mitigation strategies. Utilize this supporting information for a more comprehensive understanding of the risk matrix table template.
