This is an authoritative book that communicates the fundamentals of profitable customer engagement by proposing a customer engagement value (CEV) framework. It is a first-of-its-kind book that outlines the methods of engaging customers profitably in business-to-consumer as well as business-to-business settings. The book offers firms with definitions of the metrics within the CEV framework, and the ways to measure and maximize these metrics that can help in engaging customers profitably. The interrelationships between these metrics, i.e., how each metric impacts the other, are also explained in detail with real-life examples.
