Quantitative + qualitative risk management

Quantitative and qualitative risk analysis techniques are two approaches commonly used in risk management to identify and prioritize risks within a project or organization. While both methods aim to identify and assess risks, they differ significantly in their approach.

Qualitative risk analysis involves the assessment of risk likelihood and impact based on subjective judgment, experience, and expert opinion. This method uses methods such as a risk matrix, which categorizes risks according to their likelihood and impact, to determine their level of severity. Risk matrices are widely used in qualitative risk analysis because they are simple to use, visually appealing, and easily understandable.

On the other hand, quantitative risk analysis involves the use of statistical and mathematical tools to measure the likelihood and impact of risks. This method uses data and evidence to assess risks, quantify their probability, and measure their potential impact on a project or organization. Quantitative risk analysis is often more accurate and objective than qualitative analysis, as it relies on data and metrics rather than subjective judgment.

The main advantage of qualitative risk analysis is its simplicity and ease of use. The risk matrix is a straightforward tool that can be easily understood by stakeholders with no background in risk management. Qualitative risk analysis is also quicker and cheaper to implement than quantitative risk analysis, as it requires fewer resources, such as data and software tools.

However, qualitative risk analysis has several limitations. It relies heavily on subjective judgment and expert opinion, which can be biased and inaccurate. The risk matrix is also limited in its ability to capture complex and interrelated risks, which can result in oversimplification of risk management. Qualitative risk analysis is also less effective in assessing the probability and impact of rare events or risks that have a low likelihood of occurrence but high potential impact.

Quantitative risk analysis, on the other hand, offers a more objective and accurate assessment of risks. By using data and statistical analysis, it provides a more precise estimate of risk likelihood and impact. Quantitative risk analysis is also better at capturing the interdependencies and interactions between risks, which allows for a more comprehensive understanding of risk management.

However, quantitative risk analysis is more complex and resource-intensive than qualitative risk analysis. It requires more data, software tools, and expertise, which can be costly and time-consuming. It is also less accessible to stakeholders with no background in risk management, as it requires a higher level of technical knowledge and expertise.

In conclusion, the choice of risk analysis technique depends on the specific needs and objectives of the organization. Qualitative risk analysis is suitable for simple and straightforward projects, where the likelihood and impact of risks can be easily estimated based on expert judgment. Quantitative risk analysis is more suitable for complex projects, where the interdependencies and interactions between risks are significant and require a more rigorous assessment.


Combining both techniques can provide a comprehensive and balanced approach to risk management, allowing for the evaluation of risks in conjunction with ROI analysis.
