Some of those who read the original book, Positioning, found this sequel disappointingly short on new information. However, if you have not read the original, this book is worth reading, in part because it applies its own principles to communicate simply and briefly. Case studies are kept short and the central messages delivered efficiently then reinforced. Trout emphasizes the enormous amount of information and number of choices facing people and the consequent need for simplicity of message, and a clear position in the minds of consumers. Trout uniformly dislikes brand line extension, though he does not deal with counter-examples. The first section of the book, Understanding the Mind sets up the cognitive framework for the positioning approach. The second section, Dealing with Change, helps companies reposition themselves in consumers' minds. The third section, The Tricks of the Trade, goes into some specific strategies for penetrating the noise with your signal. There are deeper and newer books on the subject, but the clear message of this quickly-readable book is worth taking in.
