The author has taken his cue on creative thinking from Alex Osborn who, as president of B. B. D. & O. advertising agency, initiated ""brainstorming"". How the subconscious creates ideas, the practical results of impractical ideas, how to set up a brainstorming session, who to invite, the kinds of problems to tackle, how to be a good brainstorming chairman, how the brainstorm differs from the old style conference -- these are among the questions considered. Examples of brainstorming results in industry, education, labor, the armed services are included plus illustrations of individual brainstorming. The procedure to be followed -- criticism ruled out, free wheeling welcomed, quantity of ideas wanted, qualifications and enlargements on ideas sought -- in different situations is explored and amplified. The book is written in a rapidly moving, sparking manner and more than adequately elucidates this dramatic phenomenon.
