Object of play
You can use the Draw Toast exercise to introduce people to the concepts of visual thinking, working memory, mental models and/or systems thinking. This also works as a nice warm-up exercise to get people engaged with each other and thinking visually. Plus, it’s fun!
Number of players
Any number of people can play this game.
Duration: 10-15 minutes.
How to play
On paper or index cards, ask people to draw “How to make toast.”
After a couple of minutes, ask people to share their diagrams with each other and discuss the similarities and differences. Ask people to share any observations or insights they have about the various drawings. You are likely to hear comments about the relative simplicity or complexity of the drawings, whether they have people in them, how technical they are, how similar or different they are, and so on.
Depending on why you are doing the exercise you may want to point out the following:
The main point of this exercise is to demonstrate the power of visual thinking to represent information.
Visualizations of this kind tend to be easily understandable, although they are visually as rich and diverse as people. Pictures can be fundamentally correct even though they are quite different. There is no “one right type” of visualization.
When people visualize a mental model, they usually will include 5-7 elements, linked together by lines or arrows. The number of elements tends to correspond to the number of things people can hold in their working memory, also known as short-term memory (See The Magical Number Seven, Plus or Minus Two for more information).
This is also a nice warm-up exercise that is fun and gets people talking to each other.
There is an excellent TED talk by Tom Wujec which you may want to watch in preparation. It may also be useful to show to the group in sessions as a way to share insights after the exercise. Tom also has a page with ideas for extending this exercise into group problem-solving which you can find at DrawToast.com.
