Brainwriting

Choose this exercise

Purpose: Produce a shared pool of composite ideas without verbal turn competition.

Use it when: Use during ideation sessions when verbal discussions are dominated by a few voices or when participants struggle to build directly on one another's ideas.

Skip it when: Skip when the group needs to converge on an urgent operational decision or evaluate technical constraints.

Group arrangement: Tables or circles of 4 to 8 participants. Up to 3 parallel circles for large groups.

Timing: 30 minutes matches the lower end of the 30 to 45 minute range reported in the Gamestorming source.

Materials and tools

• 3 to 5 index cards per participant
• 1 pen or fine-tip marker per participant
• 1 roll of low-tack painter tape
• Star stickers or marker pens for voting
• 1 flip chart or whiteboard with markers

Before participants arrive

1. Write the prompt topic clearly on the main board and sketch a simple neutral icon representing it.
2. Arrange chairs into circles or around small tables of 4 to 8 people so cards can pass clockwise easily.
3. Place a stack of index cards and markers at each seat.

Say this to open

Welcome. Today we will generate ideas silently using Brainwriting. We write an initial idea on a card and pass it to the right. When you receive a card, treat it as inspiration: add to it, stretch it, or write a companion idea. No talking during the rounds.

How to run it

1. Frame the challenge 4 minutes

   Display the central prompt and sketch on the board. State an example to clarify the format. For example, if the prompt is 'Improving team onboarding', card line one might read 'Pair each hire with a peer buddy for 30 days.' Give participants 1 minute to ask clarifying questions about the scope.

2. Write initial cards 4 minutes

   Invite everyone to take one index card and silently write a single concrete idea responding to the prompt. Once written, hold the card face down. Stop writing when time is called.

3. Pass and build 12 minutes

   Direct participants to pass their card to the person on their right. Give participants 2 minutes to read the received card and write an addition, refinement, or connected idea directly underneath. When the chime sounds, pass to the right again. Complete 4 to 5 pass cycles until cards contain multiple layers of thinking.

4. Gallery wall and review 5 minutes

   Collect the completed cards or invite each table to tape them directly to the wall around the central topic sketch. Give participants 3 minutes to walk the wall silently and draw a star next to up to three ideas they find most compelling.

5. Whole-room debrief 5 minutes

   Gather the room facing the starred cards. Call on 3 to 4 participants to share observations on how the ideas evolved from the original line to the bottom.

Debrief questions

• Which starred idea evolved the most between the first line and the last?
• How did building silently on someone else's idea feel compared to an open verbal brainstorm?
• Where did two separate ideas combine into something nobody would have proposed alone?

Finished output: A wall display of multi-contributor index cards grouped around the central topic, marked with stars indicating group interest.

Remote

Create a shared spreadsheet or digital whiteboard with tables of 4 to 6 rows. In round one, each person types an idea in column A of their assigned row. At the timer, everyone moves down one row to column B, reads the row entry, and adds an elaboration or parallel idea. Continue for 4 to 5 columns. Participants use digital stamp tools to mark three favorite entries.

Hybrid

Seat room participants together using physical cards. Remote participants work in a mirrored shared document in breakout rooms of matching size. A co-facilitator copies remote starred entries to sticky notes on the physical wall, or reads out top remote additions during the final debrief.

Access and participation choices

• Participants may dictate their ideas quietly to a designated scribe or type on a personal tablet if handwriting is uncomfortable.
• Anyone may pass an incoming card without adding text by placing a checkmark to show they read it.
• All card contributions remain anonymous with no names attached.

If the session gets stuck

Participants start debating or explaining cards out loud during the rounds.

Remind the room gently that the exercise relies on silence so every person has time to read and think without interruption.

A participant receives a card and feels completely stuck on what to add.

Advise them that they can ask a clarifying question directly on the card, write a contrasting alternative, or simply pass the card along at the chime.
