Brainstorm agenda template (45 minutes)

Brainstorms where the loudest voice wins are a waste of quiet people's time. Silent individual ideation before the share round gets everyone's thinking into the room, not only the thinking of the people quickest to speak. It is the difference between a few ideas talked to death and a genuine set of options to evaluate.

Topic Minutes Running total
Problem framing State the problem or challenge clearly. What are we trying to solve? What are the constraints? 5 5
Silent idea generation Everyone writes ideas independently. No talking. This is non-negotiable if you want quiet voices heard. 10 15
Share round Read out all ideas, no critique yet. Clarify only if someone misunderstands. Repeat everything, even duplicates. 10 25
Cluster and vote Group similar ideas together. Vote on which ones to pursue or explore next. This is the filter, not the finale. 15 40
Next steps Decide which ideas need deeper work. Assign owners. Set a deadline to circle back with prototypes or research. 5 45

Questions

How long should a brainstorm be?
Forty-five minutes is the baseline, and most teams can do a quality brainstorm in that time if ideas are generated silently first. Ninety minutes suits a larger group or when you need time to prototype rough sketches. Much shorter and you skip the share round; much longer and people run out of ideas.
What if someone dominates the brainstorm anyway?
Silent generation gets ideas onto paper before anyone talks. If the same person dominates the share round anyway, you can ask the room what they think before inviting the dominant voice to add more. Protect both air time and thinking time; the combination unlocks ideas that would otherwise never surface.
Can we brainstorm asynchronously?
Brainstorming works asynchronously if everyone generates ideas in writing and you give them at least 48 hours to think. The synchronous share round is still worth having even with async generation, because live conversation and debate often surface connections that individual ideas never made on their own.
