Although the system offers the user substantial flexibility in selecting categories and weights, several scorecard rules apply. First, the performance category titled Diverse Supplier Development must be included in each evaluation per corporate requirements. Second, the se- lected performance category weights must sum to 100. Third, all subitems within a category must be scored on a 0-5 scale, which are added together and divided by the number of sub- items for an average category score. This average score is then multiplied by the category weight to yield the total score for that category. When all selected categories are scored, the category totals are added to arrive at a performance level ranging from 0 to 500 points, resulting in one of the following designations: 500-450 449 400 399-350 349-300
