Briefly, what is brainstorming, and why does it work? What are the four rules for brainstorming groups, and which is most difficult to follow?

What will be an ideal response?

Answer: Answers will vary. Brainstorming is used in groups to analyze a problem by generating as many ideas as possible in a short time. It works because it reduces inhibitions, encourages creativity, fosters teamwork, and allows all involved to contribute to the final solution. It occurs in two phases – the brainstorming period itself, and the evaluation period following it. During the first phase, brainstorming groups follow four rules: 1) No evaluations are permitted at this stage – any ideas can be suggested, and all are recorded without comments or responses. 2) Quantity of ideas is the goal – the more ideas generated, the more likely that a useful solution will be found. 3) Combinations and extensions of ideas are encouraged – members may not criticize an idea, but they may extend it or combine it, because one idea often stimulates a better one. 4) Freewheeling is desirable – toning down a wild idea is easy, but elaborating on a boring or conservative idea is not so easy. The first rule is the most difficult to follow, so anticipating and even practicing appropriate responses to criticisms and “idea killers” will help.
