The value of a brainstorm sits in the follow-up, not in the session itself. Start clustering immediately after the session: group ideas by theme in 30 minutes. Avoid content discussion during clustering. That comes later. Use an impact-effort matrix to prioritise: high impact + low effort goes first. Mark every remaining idea with an owner and a deadline. No owner means no action. Define 5 ideas to execute within 30 days, 5 within 60 days and 5 within 90 days. The rest go on the waiting list: not for now, but kept for later. Schedule a check-in after 30 days to discuss progress. Fail openly: an idea that doesn't work, you cross out explicitly, otherwise it lingers as debt. Communicate back to participants which ideas are alive and which aren't. People who hear nothing back won't join the next session. Live Impact guides brainstorms including the implementation track afterwards.
