Bob sells 10 units of our product each week, and makes 10 follow-up phone calls to customers to assess their satisfaction. His, and the company's, performance in sales and customer service is excellent. As an incentive, Bob's employer increases his commission on each sale. Bob now sells 15 units a week.
