Risk Matrix: An Overview

by Maya G

A risk matrix is a tool that is used to assess and evaluate the potential risks and their impact on a project or an organization. It is a visual representation that combines the likelihood and severity of risk to determine its level of priority and significance. The matrix is often used to prioritize risks and identify the best course of action to mitigate them. Risk matrices are commonly used in various industries, including finance, insurance, healthcare, and construction, to help decision-makers make informed decisions and manage risks more effectively. The matrix can also be used as a communication tool to explain risk levels and associated actions to stakeholders and decision-makers.

What is a risk matrix?

A risk matrix is a tool used to assess and analyze the likelihood and severity of potential risks or hazards. It is a visual representation that lists various risks in a table format, with each risk ranked according to its probability and impact. This matrix is typically used by businesses, organizations, and individuals to determine how potential risks should be prioritized, managed, and responded to.

It helps decision-makers to get an overview of the situation and to plan for risk mitigation activities accordingly. The risk matrix is usually divided into different levels of severity, ranging from low to high. The likelihood of a risk occurring is typically assessed on a scale from very low to very high, while the impact of the risk is assessed on a scale from insignificant to catastrophic. 

Using this information, risks are then placed in a specific quadrant of the matrix, allowing for a clear view of which risks are most likely to occur and have the highest impact.Once the risks are identified and placed on the matrix, the organization can determine the appropriate risk mitigation actions to take. 

How to create a risk matrix?

Identify potential risks: List all the potential risks that can impact your project or business.

  • Define risk levels: Define the levels of risks based on how likely it is to occur and how severe the impact will be. You can use a numerical or color-coded system such as high, medium, and low, or 1 to 5 or 10.
  • Determine the likelihood: Determine the likelihood of the risk occurring based on historical data, experience, and expert opinion.
  • Determine the impact: Determine the impact of the risk on your project or business. This can include financial losses, damage to reputation, or delays in delivery.
  • Plot risks on the matrix: Plot your identified risks on the risk matrix based on their likelihood and impact. This will help you identify which risks should be prioritized and addressed first.
  • Evaluate and manage risks: Evaluate the risks and create a risk management plan to mitigate or avoid the identified risks.
  • Review and update: Regularly review and update the risk matrix to ensure that new risks are identified and addressed, and that the risk management plan remains effective.

How to interpret a risk matrix?

A risk matrix is a visual tool used to assess the likelihood and severity of a risk. The matrix is typically divided into a grid, with the likelihood of an event occurring on one axis and the severity of the consequence on the other. The intersection of these two factors creates a risk rating, which can then be used to prioritize risks and determine appropriate risk management strategies.
  • Identify the risk event being assessed.
  • Determine the likelihood of the event occurring, using a scale ranging from low to high or another relative scale specific to your organization.
  • Determine the severity of the consequence of the event, using a scale ranging from minor to catastrophic or another relative scale specific to your organization.
  • Plot the likelihood and severity on the risk matrix.
  • Interpret the risk rating based on where it falls on the matrix. High-risk events require immediate attention and action, while low-risk events may not require any action.
  • Identify appropriate risk management strategies based on the risk rating.
  • Continue monitoring and reassessing the risk over time to ensure the effectiveness of the risk management strategies.

What are the benefits of using a risk matrix?

  • Identification of risks: A risk matrix allows the identification of potential risks before they occur.
  • Risk prioritization: A risk matrix allows the prioritization of risks based on their impact and likelihood of occurrence, so that they can be addressed accordingly.
  • Communication and collaboration: A risk matrix provides a common language for communicating about risks across different stakeholders, facilitating collaboration and decision-making.
  • Mitigation planning: A risk matrix helps in developing risk mitigation plans based on the severity and likelihood of identified risks.
  • Monitoring and control: A risk matrix enables the monitoring and control of risks, allowing timely action to be taken to mitigate or eliminate them.
  • Improved decision-making: A risk matrix provides a structured approach to evaluate risks, enabling better decision-making based on objective criteria.

What are the limitations of using a risk matrix?

  • Subjective assessment: Risk assessment rating is subjective and depends on the individual's perception and understanding of the risks, which may vary from person to person.
  • Oversimplification: Using a risk matrix might oversimplify a complex and multifaceted risk environment, limiting the accuracy of how the risks are assessed.
  • Neglect of lesser risks: In a risk matrix, there is a risk of neglecting lower probability risks, which may have significant ramifications in the future.
  • Risk score aggregation, a fundamental flaw: The risk matrix model relies on assigning both likelihood and consequence values. Since these values are subjective, the serious flaw with aggregating individual scores for likelihood and consequence is that it assumes a linear relationship between the two variables. There may be points in the matrix that have inadequate distinctions in terms of severity, leading to misinterpretations and minimizing highly critical risks.
  • Limited application: The risk matrix is only suitable for well-defined risks, and it may be inadequate for dealing with unknown and unforeseen risks.
  • Overconfidence: There is a risk of overconfidence in the risk assessment as it suggests that the risk is being managed or mitigated based on a process or model.
  • Lack of Context: The risk matrix, by its very nature, does not take context into account. This means that risks could be rated the same across projects, locations and even industries, even though they may pose a more significant threat in a particular scenario.
  • No Risk Mitigation: The risk matrix model is only suitable for assessing risk. It provides no insight into risk mitigation practices or how to address risks.

What are the limitations of using a risk matrix?

  • Identify potential risks: Determine the areas of your business that could be exposed to risks and document them in a risk register. This could include natural disasters, cyberattacks, regulatory changes, financial risks, and so on.
  • Assign likelihood and impact ratings: For each identified risk, determine the likelihood of it occurring and the potential impact on your business. Use a scale of 1 to 5 (1 being unlikely and 5 being highly likely) for likelihood and impact rating.
  • Plot risks on the matrix: Use a risk matrix template to plot the risks based on their likelihood and impact ratings. The matrix will help you determine which risks pose significant threats and require immediate attention.
  • Prioritize risks: Based on the matrix, prioritize risks to focus on those that are high or critical risks. This will help you allocate resources and develop a plan to mitigate or manage the risks.
  • Develop a risk management plan: Develop a risk management plan to mitigate, transfer, avoid, or accept the risks. Identify preventive measures, contingency plans, and response strategies.
  • Monitor and review: Continuously review the risks and assess the effectiveness of the risk management plan. Make necessary adjustments to ensure that risks are being managed effectively.
