When you have a group of people and you need to take their ideas from selected topic I can give you few tips:
1. start with mentioning expected results
2. use existing examples of realized ideas to avake inspiration
3. smile and mention funny ideas from past
4. write down every idea
5. try to include every participant
6. never focus to much only on one/two participants who have most ideas
7. after session send titles of all ideas to participants
8. send your notes to idea creator and ask for details
9. be boring when it comes to get more infos about ideas from creators
10. don’t forget to send news about status of ideas to idea creators
Brainstorming is still the best way for idea-generation, so try to do it whenever you can!
