How to run a brainstorming session
The short answer
Start with one clear question. Let people write ideas alone first so quieter voices are heard, then share without criticism. Group similar ideas, vote on the most promising, and finish by agreeing which ones to explore further, with owners and next steps.
Step by step
- 1
Frame one question
"How might we..." works better than a broad topic.
- 2
Generate alone first
A few minutes of silent writing before anyone speaks.
- 3
Share without judging
Build on ideas; save critique for later.
- 4
Group and vote
Cluster similar ideas and give each person a few votes.
- 5
Choose next steps
Pick the ideas to test, with an owner for each.
Common mistakes
- Letting the most senior person speak first.
- Criticising ideas as they come up.
- Ending without deciding what happens next.
