This technique can be used in many situations. It is often used in problem solving when you are wanting to examine all possible ideas, no matter how wrong they may be. Parts of wrong ideas are often a source of a better solution to a problem.

The purpose of a brainstorm is to generate as many ideas as possible and not to generate only good ideas. Often the process of evaluating all good and bad ideas leads to better solutions.

Brainstorming helps us to think beyond the obvious by allowing ideas to flow even if they may seem to be wrong at first.  Brainstorming allows for creativity.

When you brainstorm you should be in a group because many ideas are formed by people after hearing other people's ideas. Someone writes down ALL the ideas while the group members call out whatever comes to their minds. Rules of the brainstorm activity.
