Optionally, each score component is assigned a weight. All active score components for a scoring engine must add up to 1.0. Weight determines the relative importance of each scoring component. For instance, a score may be based on both "what year did the customer relationship start?" and "how many overdue payments does this customer have?" Since it's more important to consider the number of delinquencies over the years that someone has been your customer, the overdue payments component has more weight. The score component is multiplied by the assigned weight.

If weighting is not used, the raw score is used.
