Brainstorming is probably the best known of all the techniques available for creative problem solving. This book, by one of the worlds foremost exponents of brainstorming, begins by identifying the barriers to creative thinking and showing how they can be removed. It goes on to set out systematic procedures for organizing effective brainstorming sessions, for evaluating the ideas produced, and for introducing the brainstorming approach into an organization. This is a highly practical book, illustrated throughout by examples drawn from the author's experience with nearly eight hundred groups of managers in four continents.
