Brainstorming is just one of many tools for generating options. Indeed, the brainstorming tool can be very useful for an open-ended search in which you are attempting to generate many, varied or unusual possibilities. However, as in dealing with any complex task, one tool just does not do the whole job. To do the job right requires a number of tools as well as careful thinking and planning about which tools to select and how to apply them. Too often people misuse the term brainstorm by using it to describe any informal conversation or discussion about a question, problem, issue or challenge that needs some creative thinking.
People also use the brainstorming tool improperly.
Using a tool improperly can result in damage to the tool as well as to the object to which it is being applied. Misuses of the brainstorming tool can be avoided by remembering that it is really a very specific tool that is best used under very specific conditions, following well defined guidelines. Additionally, begin with a concisely stated task or problem statement that is open-ended, free of limiting criteria and invites many possibilities. Remember that group brainstorming should be supplemented by individual ideation whenever possible. It is just as important and helpful to know and apply the basic guidelines and procedures for using brainstorming effectively and appropriately during the inventing process as it is for any other creative task or challenge.
