Marketing, to be done right, is among the most challenging and difficult functions in any enterprise, and particularly in the highly fluid customer environments of today. When done right, it also yield enormous benefit (i.e., profits) to the enterprise.
This book covers very well the three fundamental concepts that lie at the heart of effective and successful marketing - identifying and packaging value, messaging and communication to the customer of that value, and value selling - the ability to follow through on that messaging and convering it into a profitable transaction for both. The book falls behind in not being able to get into the operational aspects of this pocess, but I still think it serves enormous value just to be able to articulate these core powerful concepts really well.
