This is the type of book that can change an entire corporate vision. The authors are meticulous in presenting their philosophy, and back every word with carefully researched examples from best practice companies. Unlike many of the "quick read" publications that present a superficial view of service (particularly from a marketing perspective), this book is clearly the result of several years work in the field. Every corporate manager who is serious about customer value management needs to take some time out to study the Service Profit Chain.
