The word brainstorming has gotten a bad rap from some who write on the www. The problem they seem to have is that their experiences with the subject have been the antithesis of purposeful brainstorming.
So I propose to use ‘idea generation’ instead of brainstorming. That is the purpose of most brainstorming sessions any way.
A good idea generation session has a clear goal but also leaves lots of room for playing around with ideas and exploring several different avenues that turn up.
A good idea generation session also will produce some ideas and directions that seem immediately applicable while others should be put in the parking lot to be reintroduced and explored at a next meeting.
