We often use team to come up with creative insights.
Brainstorming in groups
Independent individual bring more considerably more and better ideas than the same number of individual gathered in a team.

Why do teams perform worse?
- Production blocking
- Evaluation apprehension (fear of judgement)
- Anchoring (elaborate only on one first idea damaging ideas diversity)
- Social loafing
Teams are completely oblivious of their bad performance in brainstorming: there is an illusion of group productivity.
- Solicit creative ideas from teammates individually, before the meeting by email | face to face | surveys.
- Or at least, ask teammates to think some minutes individually and write their idea on paper.
Nominal group technique
- Step 1: Each participant works alone to write down his/her individual ideas
- Step 2: Each participant presents his/her ideas and writes them down on the board (no discussion is allowed until all ideas are on the board)
- Step 3: After all ideas have been presented, teammates conduct an open discussion of all ideas for clarification purposes only. No evaluative comments allowed.
- Step 4: Group members vote by secret ballot to rank-order ideas
- Set a tight timeline for a brainstorming session (e.g., 10 minutes)
- After 10 minutes, challenge your team to double its performance in the next 10 minutes
- 93% of teams increase per-person productivity
- Average productivity increase is 57% !
