Object of Play
This format for brainstorming compresses the essentials of an ideation session into one short format. The numbers 3-12-3 refer to the amount of time in minutes given to each of three activities: 3 minutes for generating a pool of observations, 12 for combining those observations into rough concepts, and 3 again for presenting the concepts back to a group.
Essential to this format is strict time keeping. The “ticking clock” forces spontaneous, quick-fire decisions and doesn’t allow for overthinking. With this in mind, a group that is typically heavily measured in its thought process will benefit the most from this exercise but will also be the hardest to engage. Given its short duration (30 minutes total for 10 participants), 3-12-3 Brainstorming can be used as an energizer before diving into a longer exercise or as a standalone, zero-prep activity. It works equally well in generating new ideas as improvements to existing ones.
Number of Players
This is a fast exercise that gets slower as more participants are added. With up to 10 participants working as partners, the speed of the exercise makes it an energy builder. Working beyond 10 may require creating groups of three instead of pairs to keep from getting slowed down.
Duration of Play: 21–30 minutes, depending on number of participants
How to Play
You will need a topic on which to brainstorm ideas, boiled down to two words. This could be an existing problem, such as “energy efficiency,” or it could be focused on creating something new, such as “tomorrow’s television.” Although the two words could be presented as a full challenge question, such as “How
will tomorrow’s television work?” it is best to avoid doing this right away. By focusing on two words that signify the topic, you will aim to evoke thinking about its defining aspects first, before moving into new concepts or proposing solutions.
To set up the game, distribute a stack of index cards and markers to all the participants. Everyone should have a fair number of cards available. The game should begin immediately after the rules have been explained.
- 3 Minutes: Generate a Pool of Aspects. For the first three minutes of the exercise, participants are asked to think about the characteristics of the topic at hand and to write down as many of them as they can on separate index cards. It may accelerate the group’s process to think in terms of “nouns and verbs” that come to mind when thinking about the subject, or to free-associate. As in all brainstorming, no filtering should be put on this phase, in which the goal is a large pool of aspects in a small window of three minutes.
- 12 Minutes: Develop Concepts. At this point the group is divided into pairs. Each team draws three cards randomly from the pool. With these as thought starters, the teams now have 12 minutes to develop a concept to present back to the larger group. If the two topic words are sufficient to explain the challenge, the clock starts and the teams begin. If there is any doubt, reveal a more fleshed-out version of the topic’s focus, such as “How will we become more energy-efficient next quarter?” In developing concepts to present, teams may create rough sketches, prototypes, or other media—the key is in preparing for a short (three-minute maximum) presentation of their concept back to the group.
- 3 Minutes: Make Presentations. When presenting to the larger group, teams may reveal the cards that they drew and how the cards influenced their thinking. Again, tight time keeping is critical here—every team should have a maximum of three minutes to present their concept. After every team has presented, the entire group may reflect on what was uncovered.
