You have to have trust in your team and let them define much of how they will work. Build in as much flexibility as possible into your idea generation process. Create rules only when necessary, and start with as few rules as possible. Be responsive to what s working, and make adjustments as you go. Avoid rigor and hierarchy.
Flexibility allows minds to open, and open minds are fertile for creative thoughts.
Brainstorming meetings are a common exercise for generating ideas, but few know how to organize and run them well. Often personalities don t mix in the right way for these kinds of meetings to be effective. Some people are just not open enough in group settings to listen to new ideas, or to share their potentially embarrassing ideas with others. These sessions tend to work best when there is an experienced leader or organizer, who knows how to facilitate a session. Someone has to be responsible for keeping the meeting focused, but open enough that many ideas are presented and discussed.
