Such attention to customers requires a closed-loop process in which every function worries about delivering a good experience, and senior management ensures that the offering keeps all those parochial conceptions in balance and thus linked to the bottom line. This article will describe how to create such a process, composed of three kinds of customer monitoring: past patterns, present patterns, and potential patterns. (These patterns can also be referred to by the frequency with which they are measured: persistent, periodic, and pulsed.) By understanding the different purposes and different owners of these three techniques—and how they work together (not contentiously)—a company can turn pipe dreams of customer focus into a real business system.
