# Risk Matrix in Project Management: What is it and How to Use it

The **risk matrix** is a concept we’ve been getting close to anytime project management is mentioned. Risks are a part of any project, and it’s clear that, unfortunately, there’s no way of knowing for sure when and where they’ll occur.

While it’s not impossible to go through a project without suffering from any risks or consequences, that’s very much improbable. In everything we do in life, the Law of Murphy (everything that can go wrong, will) is right around the corner, ready to attack.

What we can do regarding risk probability is prevent project risks and be prepared for them, and a risk matrix can be quite helpful.

## What is a risk matrix in project management?

The risk matrix is a widely used project management technique for risk analysis. It’s a tool that will provide information about the probability of a risk happening and if it’ll be a major or a minor problem.

**The formula for calculating risk is:** Risk = Probability x Severity.

Once the risk assessment is made, in terms of calculating the likelihood and severity of each risk, it’s possible to organize them along a matrix to calculate risk impact ratings.

This exercise is critical since it helps prioritize the risks in a project and then manage them.

## What are the steps to be taken in a risk assessment?

To ensure a comprehensive approach to managing potential issues, it’s essential to follow structured steps in risk assessment, from identifying risks to continuously monitoring their impact. This is a step-by-step guide on how to implement the risk management process:

1. **Identify risks:** Identify potential risks through brainstorming, expert consultations, and analyzing historical data. This comprehensive identification process ensures that all possible risks are recognized and documented, providing a foundation for further assessment.

2. **Assess likelihood and impact:** Evaluate each risk’s likelihood of occurrence and its potential impact. This step involves scoring risks based on their probability and severity, which helps in understanding the extent of their potential effects on the project.

3. **Calculate risk ratings:** Use a risk matrix to combine the likelihood and impact scores into an overall risk rating. This calculation helps in prioritizing risks by quantifying their potential threat, allowing for effective focus on the most critical risks.

4. **Develop mitigation strategies:** Formulate action plans to address the highest-priority risks, including preventive measures and contingency plans. By developing these strategies, you prepare to manage risks proactively and reduce their potential impact on the project.

5. **Monitor and review:** Continuously track the identified risks and the effectiveness of mitigation efforts. Regular reviews and updates ensure that the risk assessment remains accurate and relevant, adapting to any changes or new risks that may arise.

The risk matrix is part of the program of the APM – one of the best pmp certifications.

## Risk matrix example

The risk matrix is a standard tool in a project risk management plan and allows the project manager and team members to analyze every risk by determining each event as high, medium, or low impact.

The risk matrix can be calculated using different templates, such as a 5×5, but also 3×3 or 4×4. Once the severity and likelihood of each risk are assessed, it’s possible to prioritize risks and prepare for them as needed.

To show an example of a risk matrix here, we’ll use a 4×4 risk assessment matrix.

The first thing to do is to identify as many potential risks as possible. A brainstorming session with the project team is ideal for analyzing and identifying potential risks related to the project itself.

It’s also helpful to organize these risks by typing in separate documentation. The assessment form or risk registry should look something like this.

### Risk matrix template

Potential Risks | Likelihood/Probability | Impact/Severity | Risk Rating |

risk a | – | – | – |

risk b | – | – | – |

risk c | – | – | – |

risk d | – | – | – |

#### Likelihood / Probability

Follow up by determining the risk likelihood and the scale you’ll be using. Usually, the likelihood levels follow the levels of the matrix.

So, using a 4×4 matrix means we’ll have four risk levels. The complete risk matrix is the 5×5. Let us consider these four:

- Very Unlikely / Unlikely
- Possible
- Probable
- Very Likely

Potential Risks | Likelihood/Probability | Impact/Severity | Risk Rating |

risk a | 4 | – | – |

risk b | 3 | – | – |

risk c | 1 | – | – |

risk d | 3 | – | – |

#### Impact / Severity

Next up, the impact or severity scale needs to be ranked. In this case, we’ll also consider four levels.

- Very Low / Low
- Moderate
- Significant
- Catastrophic

Note that these scales are completely customizable according to your needs and project specifications.

Potential Risks | Likelihood/Probability | Impact/Severity | Risk Rating |

risk a | 4 | 4 | – |

risk b | 3 | 4 | – |

risk c | 1 | 3 | – |

risk d | 3 | 2 | – |

#### Calculate the risk rating

Next, it’s time to calculate the risk rating by using the formula likelihood/probability x impact/severity. Since we’re working with a 4×4 matrix, the higher value we will get is 16. This would be the highest-ranking risk.

These are the ones that can cause the project to go off the rails, so these need to be closely dealt with. Use this information to be preventive regarding this risk.

Potential Risks | Likelihood/Probability | Impact/Severity | Risk Rating |

risk a | 4 | 4 | 16 |

risk b | 3 | 4 | 12 |

risk c | 1 | 3 | 3 |

risk d | 3 | 2 | 6 |

#### Final Risk Matrix

So, risk A is the most dangerous one. The other ones can also be organized at different levels. For example, in this particular case, 1-6 could be low, 7-11 medium, and 12-16 high.

Now all the information is available and ready to be inserted into the matrix. The risks will be identified and shortly described between the two axes. Some risks may fall on the same metric.

Impact / Severity | |||||
---|---|---|---|---|---|

Probability / Likelihood | 1 | 2 | 3 | 4 | |

4 | risk a (16) | ||||

3 | risk d (6) | risk b (12) | |||

2 | |||||

1 | risk c (3) |

To customize even further, the matrix can be color-coded, for example, green for low risk and red for high risk.

## The benefits of a risk assessment matrix

Developing a risk assessment and then the matrix calculations is a critical step that is part of the project manager’s job and functions.

It’s fundamental to realize your assets and know how to handle and protect them. This is the **main benefit** of a risk assessment matrix.

Regularly performing a risk assessment is the key to figuring out what potential threats might harm the project’s life cycle, which is benefit number two.

Understanding the likelihood and hypothetical severity of the identified threats. Here is the chance to calculate the risk matrix. Doing this allows the opportunity to be proactive regarding risks instead of reactive.

The risk assessment matrix is the tool that allows the implementation of proactive measures to minimize the impact of the project’s risks.

## What are the disadvantages of the risk matrix?

Here are five of the most relevant and common disadvantages of using a risk matrix:

**Neglect of Interdependencies:**Risk matrices often fail to consider the interactions and dependencies between different risks, resulting in an incomplete understanding of the overall risk environment.

**Subjectivity:**The evaluation of risks often depends on personal judgment, which can lead to inconsistent and biased assessments.

**Oversimplification:**Risks may be too broadly categorized, missing important details and nuances that are crucial for effective risk management.

**Static nature:**A risk matrix provides a snapshot of the risk landscape at a specific time and does not account for changes over the course of the project, making it quickly outdated.

**Inaccuracy:**Simplified scales can lead to inaccurate risk ratings if the actual probability and impact do not fit neatly into the predefined categories.

TIP: A Risk matrix is a good asset to include in your project report.

## Conclusion

This kind of tool has as much of an analog as it is digital, and the major benefit is that it can be used to manage multiple projects. However, every project faces unique risks, and these issues need frequent reevaluation.

Unfortunately, using a risk matrix doesn’t solve every issue, but it will help reduce both the probability and impact of a problem. Use it in your strategy.
