Brainstorming
From open-encyclopedia.com - the free encyclopedia.
Brainstorming is an organized approach for producing creative ideas by letting the mind think without interruption. 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.
It is a means of enhancing divergent production, aiming to facilitate problem solving through the maxim quantity breeds quality. The greater the number of ideas generated, the greater the chance of producing a radical and effective solution.
An essential element of brainstorming is putting criticism 'on hold'. Instead of immediately stating what might be wrong with an idea, the participants focus on extending or adding to it, reserving criticism for a later 'critical stage' of the process. By suspending judgment, you create a supportive atmosphere where participants feel free to generate unusual ideas.
Brainstorming has many applications but it is most frequently used in:
- New product development - obtaining ideas for new products and making improvements to existing products
- Advertising - developing ideas for advertising campaigns
- Process management - finding ways of improving business and production processes

Procedure for a typical brainstorming session
- A moderate size room is equipped with about a dozen chairs in the shape of a hollow square so that each participant is looking at the others in the group. A flipchart, blackboard, or overhead projector is placed in a prominent location. The room is free of telephones, clocks, or any other distractions.
- Between six and twenty people with an interest in the subject (although not necessarily experts) are invited to participate. Generally the participants are not given details about the subject to be discussed before hand.
- Write on the flipchart (or blackboard) a statement of the subject or problem that will be discussed. This is often presented as a question.
- Choose one person to write down the ideas generated. Ideas should be written concisely but without paraphrasing. The recorder should state the idea in the words she has written to ensure that it expresses the meaning intended by the originator.
- Choose one person to facilitate the process. This involves encouraging participation by everyone and maintaining a criticism free, uninhibited atmosphere. Encourage even wild and seemingly ridiculous ideas.
- After 5 to 20 minutes the facilitator calls an end to the idea generation phase.
- Review the list from top to bottom to ensure everyone understands the ideas. Eliminate from the list any duplications. Remove any obviously ridiculous suggestions.
- Thank all participants and give them each a token recompense as a sign of appreciation.
Nominal group technique
Nominal group technique is a type of brainstorming that introduces structure to the process. It is useful in ensuring that all participant have an equal say and can be used to generate a rank-ordered list of ideas.
Typically each participant is asked to write down their ideas. Then the moderator asks each participant in turn to express one of the ideas that they have written down. The moderator writes down each idea on the flipchart. Then each participant copies the group's final list on a blank page giving each idea a score. The pages are collected from each participant and the scores summed, providing a rank-ordered list.
