" One of my favorite examples comes from the heady days of America Online (AOL). The company would routinely send out CDs in an attempt to get people to sign up for its product. One group within the company, responsible for acquisitions, was given financial incentives for hitting subscription goals. And so all tactics were designed to do just that: sign people up. There were offers of 100 free hours in the first month, which became 250 free hours, then even 700 hours. I remember when the offer got to 1,000 free hours, as long as they were used in the first 45 days (which left 1.7 hours of sleep per night for anyone who could take advantage of the promotion). It worked. Whatever tactics the acquisition group members developed were designed to do one thing and one thing only—maximize their bonus. The problem was there was another group responsible for retention; they had to find ways to get all the people who had canceled their
subscriptions to come back. By creating a system in which each group was preoccupied with its own metrics without concern for anyone else’s or even what would serve the company best, the leaders of AOL had effectively incentivized their people to find ways to cost the company more money. "
