Brainstorming is a process used to generate ideas by engaging in an open group discussion. Each person in the group is encouraged to come up with as many ideas as possible, no matter how outlandish they may initially appear to be. A critique of the resulting ideas is only allowed after the initial idea generation phase has been completed. By barring any initial negative feedback on suggestions, people feel less inclined to keep ideas to themselves. This technique is frequently used to derive “out of the box” alternatives to improve processes and products.
