Customer Satisfaction

Note that customer satisfaction is often at odds with other goals. High scores imply high costs, and that could imply low margins. From a competitive standpoint, your demand is driven by the spread between your score and your competitors' scores. If everyone scores the same, whether at 10 or 50, they sell the same number of units.

The customers score the products each month. Sales distribution in that month is determined in a probabilistic fashion. Say there are five products and the scores are (20,20,20,20,20). Each would see identical demand. Likewise each would see identical demand if the scores were (1,1,1,1,1) or (100,100,100,100,100). If there is a spread, however, the top scoring product is more likely to sell than the bottom scoring product. Say the scores are (40,30,20,9,1). The total is 100. The first product's sales that month would be 40/100 = 40%. The bottom product's sales would be 1%.
