To conduct a brainstorming session:
1. Review the guidelines for brainstorming.
2. Clearly state the question and the time limit (15-60 minutes).
3. Members take turns calling out ideas. (For structured brainstorming, this is done in order. Members pass when an idea does not come to mind quickly, but may contribute on the next round).
4. Record each idea exactly as presented on a flipchart/board/post-it note, visible to all group members.
5. After all ideas have been presented, discus the ideas to ensure that all member have the same understanding of each idea. Eliminate duplications or out of context suggestions.
