An organised approach for producing ideas by letting the mind think without interruption. The term was coined by Alex Osborn. Brainstorming can be done either individually or in a group; in group brainstorming sessions, the participants are encouraged, and often expected, to share their ideas with one another as soon as they are generated. The key to brainstorming is not to interrupt the thought process. As ideas come to the mind, they are captured and stimulate the development of better ideas. Brainstorming is used for enhancing creativity in order to generate a broad selection of ideas in leading to a unique and improved concept.
