Typically companies use score for credit approval, loan approval, and many other tasks. People often say approve them if score is above 443, or reject them if score is lower than 339, etc. However, scores provided by different vendors and different models have different meanings. A score of 600 from vendor A and from model B usually have different risks of default. I am thinking that if it is a better business practice to talk about probability, or likelihood of default. Tell decisions makers the likelihood of default is 50% by vendor A, 60% by vendor B, or 90% by model C. It will be easier for the decision maker to evaluate the risks, he can easily decide to chose the minimum, maximum, or average. It is also easier for developers to use some techniques to compare and combine risk assessments from different and ad hoc sources.If the company chooses to use score from another vendor or a new model, there will be no need to tell people that score criteria has changed, because the the criteria of likelihood doesn't change.
