Score

The score output by PPM is a measure of the association between a process with the symptom and also with some other dimension value. This measure is a number between 1 and 1000. The value of the measure represents the importance of the root cause. The closer the value moves to 1000, the stronger the effect of the root cause becomes.

An association may promote the symptom, meaning that the root cause and the symptom extraordinarily often occur together, or may inhibit the symptom, meaning that they seldom occur together. In the example above, a customer coming from China is associated with having a complaint, so the root cause China promotes the occurrence of complaints.

Note that the score does not necessarily correspond to the percentage of symptomatic processes. It takes other factors besides the percentage into account, such as the relative frequencies of the dimension values.
