BRAINSTORM: a spontaneous group discussion to produce ideas and ways of solving problems. Produce an idea or way of solving a problem by holding a spontaneous group discussion: a brainstorming session. 
A sudden bright idea: a harebrained idea.
I’ve heard tales of entire writing groups involved in brainstorming sessions. The author will toss out info or questions allowing members to make suggestions or give solutions and ideas. This might go back and forth the entire meeting, or they may time their sessions allowing other members to take advantage of the process. The session is recorded for the author’s benefit.
When you’re brainstorming a new idea, do you enlist the help of others? Give me one brainstorming tip I can use alone.
