In this day and information age, it is all about those who are able to utilize the information they have to maximize potential, and these two University of California, Berkeley, professors have assembled the guide to do just that. The nuts-and-bolts approach to finding ways to differentiate one's product from all the others, and a how-to guide to simplify and improve customer interface, are both helpful, and the idea of managing intellectual properties to maximize value is infinitely superior to just protecting them from competitors. Some of the information delves into building positive feedback for the product, and every businessperson probably needs to know some of the legal ins and outs of building alliances and the ramifications of competition. Shapiro and Varian seem to be targeting the hard-core student of business here (not the casual browser); their approach is extremely thorough, and there is much practical information for those willing to wade through the information rules.
