Brainstorming is the most famous group creativity technique in the world. Its power comes from one simple rule: Separate generation from evaluation. By creating a “judgment-free zone” where no idea is a bad idea, groups can leverage collective synergy to find disruptive solutions that no individual would have reached alone.
The Four Golden Rules
To make brainstorming work, you must follow Alex Osborn’s four original rules:
- Focus on Quantity: The more ideas, the better. Quality comes from volume.
- Withhold Criticism: No judgment, no “that won’t work,” and no eye-rolling.
- Encourage Wild Ideas: The crazier, the better. It’s easier to tame a wild idea than to invigorate a boring one.
- Piggyback: Use other people’s ideas as fuel for your own. Combine and improve.
Define the Question
State your problem clearly and visibly.
Example: “How can we increase customer loyalty for our online subscription service?”
The Rapid-Fire Round
Call out ideas as fast as they come. A scribe should record every single one verbatim on a whiteboard.
- “Give a free month every year.”
- “Create a secret ‘VIP’ channel for long-term users.”
- “Send them a physical birthday card.”
- “Let them vote on our next product feature.”
- “Give them a ‘founder’ badge that never expires.”
Piggyback and Pivot
Look at the ideas already on the board. How can you combine two of them or change one slightly?
“Building on the ‘Founder Badge’ idea: What if that badge gave them a permanent 5% discount on all future products too?”
Evaluate and Select
Only after the energy dies down do you start judging. Group the ideas into themes (e.g., “Rewards,” “Community,” “Personalization”) and vote on the top 3-5 to prototype.
Practice
Problem: “Reducing office waste.” One person says: “Get rid of all trash cans.” How do you “tame” this wild idea into something practical?
