Whether an event takes place depends on many factors. Therefore analysing multiple risks is best done through a Risk Matrix. Having only the Risk Magnitude does not give you a lot of information because you don’t know the Likelihood or Impact of the risk. You could then say that a low risk <5 would be acceptable, while a risk magnitude of 15 or above unacceptable. The formula: Risk Magnitude = Severity x Likelihood. Calculating a Risk Magnitudeįurthermore, you can also calculate the Risk Magnitude (or risk index) by multiplying the Risk Likelihood by the Risk Severity. The Risk Matrix typically has four sections, each representing a different Risk Magnitude. Risk Severity (or Risk Impact) signals the Risk’s negative consequence on a project. Together with the Risk Severity, the Risk Likelihood is part of the Risk Matrix (or Risk Diagram), a tool used to help identify, assess, and prioritise risks. Knowing what the Likelihood is of several Risks, enables prioritisation. Risk Likelihood helps to identify and prioritise risks in Risk Management. Why is Risk Likelihood significant for Risk Management? Here it is typically better to be safe than sorry and choose a higher likelihood. It might be difficult to assess a low likelihood when speaking about 0.1 % and 1 %. It is essential to discuss this with your team before making any decisions. Maximum Likelihood: Certain or almost certain to occur (100%)Īs you can see, the industries and companies will have different standards for what is considered a low, moderate, or high Likelihood.High Likelihood: Will frequently occur (between 10% and 100%).Medium Likelihood: Will sometimes occur (between 1% and 10%).Low Likelihood: Will seldom occur (between 0.1% and 1%).Minimum Likelihood: Will almost never occur.Here we will use an ordinal scale from A to E (or 1 to 5). Now let’s say we have components that must comply with ECSS Standards. High Likelihood: Estimation crashes more than 10% of the time.Moderate Likelihood: Estimation crashes 5-10% of the time.Low Likelihood: Estimation it crashes less than 1% of the time.Let’s say we have an important meeting with a client and our computer has crashed before, so it is likely to crash again. There is no precise answer, as it may depend on the industry, company, and situation. Travelling to Mars has many Risks, more ships will decrease the likelihood of failure of the whole project. Use a more descriptive ranking system with names, for example, low to high.Rank the likelihood of something happening with numbers, for example, 1 to 5.There are two ways to use an ordinal scale for Risk Likelihood: Finally, it is easy to communicate ordinal scale rankings to others. Second, it can be helpful in making decisions, since you can rank different options in order of magnitude. Using an ordinal scale has several benefits. When it comes to Risk Likelihood, you can use an ordinal scale to rank the likelihood of something happening on a scale from 1 to 5. In other words, it is a scale that allows you to put things in order from smallest to largest (or vice versa). Describing the Risk Likelihood with the Ordinal scaleĪn ordinal scale is a way of ranking items in order of magnitude, or size. In other words, the probability is the anticipated percentage of possibilities that an outcome will take place based on a parameter of values. When using a quantitative assessment, you typically speak about Risk Probability and percentage. This is in comparison with quantitative assessments, which use data and numbers. Risk Likelihood means the possibility of a potential risk occurring, interpreted using qualitative values such as low, medium, or high. Qualitative assessments are based on opinions it is difficult to put an exact number on the assessment. Risk Likelihood is a qualitative assessment that explains how likely a Risk will occur. This article discusses the meaning of Risk Likelihood and how you can calculate it and decrease it. It is used by decision-makers and Risk Managers in various fields and industries. Risk Likelihood is a term that describes the likelihood of something going wrong.
