![]() ![]() 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. A Risk has been assessed as follows: Probability = H, Cost = L, Schedule = M and Safety = VH.Risk Likelihood is a term that describes the likelihood of something going wrong. The overall impact is determined by choosing the row that refers to the risk Probability in the Probability and Impact Diagram grid (Risk Scoring Matrix) and choosing the cell in that row that is closest to the Risk Score.Į.g. The Risk Score is then average of all these scores. When using Average Individual Impact each impact type is combined with the Probability to select a Score from the Probability and Impact Diagram grid (Risk Scoring Matrix). The overall impact is then combined with the Probability to select the risk Risk Score from the Probability and Impact Diagram grid (Risk Scoring Matrix).Īverage Individual Impact option selected A risk is assessed as follows:Īverage numerical impact = (2 + 3 + 5) / 3 = 3.33 A risk register has 3 Impact Types and 5 impact values (VL, L, M, H and VH). The average of these is used to determine the Overall Impact.Į.g. When using Average of Impacts option each risk impact is given a numeric value: Negligible=0, VL=1, L=2, M=3, H=4, VH=5). The overall impact is then combined with the Probability to select the Risk Score from the Probability and Impact Diagram grid (Risk Scoring Matrix). The overall impact for a risk is set to the highest of all the impacts. Risk scoring methods explained: Highest Impact option selected Each risk impact (schedule, cost, quality etc) enteredĪ risk scoring matrix includes probability threshold values, schedule, cost impact threshold values, and any additional user-defined impact threshold values, which are all used in the calculation of the risk score.Risk scoring method selected for the Risk Scoring Matrix (Highest Impact, Average Impact, Average Individual Impact).The scores entered in the assigned Risk Scoring Matrix (Probability and Impact Diagram grid).Risk Scoring Matrix assigned to the project.The scores are used to help determine if the risk should be addressed during the course of the project, or if the risk does not present a significant impact to the cost or schedule of the project. The score is used to give an overall rating of a risk depending on the probability and impact thresholds assessed in the project. ![]()
