Brainstorming session templates you can run today
Last reviewed by The thinkdrop facilitation team
A brainstorming template is a timed agenda plus starter prompts, so the session begins without setup. The five that cover most needs are a 30-minute quick brainstorm, a 60-minute classic session, a sprint retrospective, a problem-solving session using how-might-we framing, and an asynchronous board left open for 24 hours.

Step by step
- Pick the template that matches your time, not your ambition — A well-run 30-minute session beats a 90-minute one that loses the room at minute forty. Choose by the time you genuinely have.
- Replace the question with your own — Each template's starter cards are prompts, not answers. Swap in the specific question you need ideas for before you share the board.
- Post the agenda where participants can see it — People contribute differently when they know a grouping phase is coming — they write more freely, because they know filtering happens later.
- Run the silent phase without exception — Every template starts silent. It is the single step that most changes the range of what gets written.
- Close the board and send the summary the same day — The output of a session is a written record with owners. Sent within the hour it gets read; sent two days later it does not.

- 3–8 min — Silent card writing, no talking
- 8–18 min — Build on each other's cards
- 18–25 min — Group into themes and react
- 25–30 min — Pick two, assign owners
Starter cards
- What would we try if we had one week and no budget?
- What has a customer asked for twice this month?

60-minute classic session
A significant question with a mixed group · 60 minutes
Agenda
- 0–5 min — Frame the question, ground rules
- 5–10 min — Silent generation
- 10–30 min — Build, extend, combine
- 30–45 min — Cluster into 5–8 named themes
- 45–55 min — Vote and pick the top three
- 55–60 min — Owner and date for each
Starter cards
- What is the real problem behind the one we were asked to solve?
- Who is affected by this that is not in the room?
- What would make this ten times easier rather than ten percent better?
- What is the boring option we are avoiding?

- What constraint would we remove first?
Sprint retrospective
A team closing a sprint or a release · 45 minutes
Agenda
- 0–5 min — Recap the sprint, no discussion
- 5–12 min — Silent cards: went well / did not / change
- 12–30 min — Discuss the most-reacted cards only
- 30–40 min — Agree two changes for next sprint
- 40–45 min — Owners and how we will know it worked
Starter cards
- What went well that we should keep doing deliberately?
- Where did we lose the most time?

- What did we decide but not do?
- What should we stop doing entirely?
Problem-solving (how might we)
A recurring problem nobody has framed properly · 60 minutes
Agenda
- 0–10 min — Describe the problem, no solutions allowed
- 10–20 min — Rewrite it as three "how might we" questions
- 20–25 min — Vote on which question to solve
- 25–45 min — Generate ideas against that one question
- 45–60 min — Cluster, choose, assign
Starter cards
- How might we remove the step people complain about most?
- How might we make the failure obvious before it costs anything?
- How might we solve this for the ten percent hardest cases?
- How might we make the current workaround unnecessary?
- How might we solve this without building anything?
Asynchronous 24-hour board

Starter cards
- Add one idea you would not say out loud in a meeting.

- What is missing from this board?
What a good template actually contains
A template earns its place by removing decisions from the facilitator at the moment they are busiest. That means three things: a timed agenda with phase boundaries, a small set of starter prompts so the board is never empty, and an explicit end state — what the group leaves with. Anything beyond that is decoration.
Adapting a template to your team
Shorten the generation phase before you shorten the grouping phase; groups usually have enough ideas and too little time to make sense of them. If your team is quiet, add a second silent round rather than more discussion. If it is loud, run generation entirely on cards and use speech only during clustering.
Which template to use
| Situation | Template | Length |
|---|---|---|
| Narrow question, little time | 30-minute quick brainstorm | 30 min |
| Significant question, mixed group | 60-minute classic | 60 min |
| End of a sprint | Sprint retrospective | 45 min |
| Recurring, badly framed problem | How might we | 60 min |
| Team across timezones | Asynchronous board | 24h + 20 min |
Frequently asked questions
What is a brainstorming template?
A timed agenda plus starter prompts, so a session can begin without the facilitator designing it first.
How long should a brainstorming template run?
Thirty minutes for one narrow question, sixty for a significant one, or asynchronously over 24 hours for distributed teams.
Can I run these templates for free?
Yes — you can start any of them on a free thinkdrop board and share the link with your team.
How many starter cards should a template have?
Five or six: enough that the board is never empty, few enough that they do not define the answer.
