Osborn’s method

Osborn’s method for brainstorming

Osborn claimed that two principles contribute to “ideative efficacy,” these being :

>>>Defer judgment,
>>>Reach for quantity.

Following these two principles were his four general rules of brainstorming, established with intention to :

>>> reduce social inhibitions among group members.
>>> stimulate idea generation.
>>> increase overall creativity of the group.

Go for quantity: This rule is a means of enhancing divergent production, aiming to facilitate problem solving through the maxim quantity breeds quality. The assumption is that the greater the number of ideas generate the bigger the chance of producing a radical and effective solution.
Withhold criticism: In brainstorming, criticism of ideas generated should be put ‘on hold’. Instead, participants should focus on extending or adding to ideas, reserving criticism for a later ‘critical stage’ of the process. By suspending judgment, participants will feel free to generate unusual ideas.
Welcome wild ideas: To get a good long list of suggestions, wild ideas are encouraged. They can be generated by looking from new perspectives and suspending assumptions. These new ways of thinking might give you better solutions.
Combine and improve ideas:As suggested by the slogan “1+1=3”. It is believed to stimulate the building of ideas by a process of association.

Applications
Osborn notes that brainstorming should address a specific question; he held that sessions addressing multiple questions were inefficient.

Further, the problem must require the generation of ideas rather than judgment; he uses examples such as generating possible names for a product as proper brainstorming material, whereas analytical judgments such as whether or not to marry do not have any need for brainstorming.

Groups
Osborn envisioned groups of around 12 participants, including both experts and novices. Participants are encouraged to provide wild and unexpected answers. Ideas receive no criticism or discussion. The group simply provides ideas that might lead to a solution and apply no analytical judgment as to the feasibility. The judgments are reserved for a later date.
