Speed sketching vs. art/perfectionism

For a Five Sketches™ design session, I ask design participants to bring at least five substantially different ideas to the table, in the form of sketches. A common initial reaction is: “…But I can’t sketch!”

Many design participants believe they cannot draw. To be honest, I believe that about myself. People who feel they cannot draw tend to extend that belief to encompass design sketching, as well. However, I have learned to distinguish between drawing (below, left) and sketching a software design (below, right).

Drawing versus sketching

Software design does not require drawing, only sketching. From experience, I can tell you that sketching is easy once you realise that the goal is to produce only rough and low-fidelity ideas, not decorative and high-fidelity pictures.

Occasionally, I encounter a design participant who has trouble with sketching. I once had a participant who was so self-conscious of her sketching ability that she was paralyzed during the rapid iteration phase, when the design participants are quickly mashing up the sketches with borrowed and new ideas to produce additional sketches. I noticed that this participant was always busy—talking or wiping the board or replacing the snacks—but never sketching. This avoidance, and the underlying mental block, was an impediment to the whole team. Like all generative design processes, Five Sketches™ relies on its participants to saturate the design space with ideas. If a participant isn’t participating, it increases the project risk.

To pre-empt this mental block and to reduce the project risk, during Five Sketches™ training, I now introduce a quick speed-sketching exercise. Speed sketching is a race against the clock. With pen and paper ready, before each round, I give the participants five seconds to think, and then:

  • Speed sketching in seconds!10 seconds to sketch a cell phone.
  • 8 seconds to sketch a sandwich.
  • 6 seconds to sketch an airplane.
  • 4 seconds to sketch a ship.
  • 2 seconds to sketch a house.

After each sketch, the participants look at the other sketches. I ask them to identify the details that make the sketched object recognisable. There isn’t time to draw a high-fidelity rendering, so the sketches are rough and have few details.

Interestingly, with few details the sketched objects are still clearly recognisable. Participants learn that detail and fidelity aren’t needed. By the last round of sketches—the “2 seconds to sketch a house” round—participants have seen that everyone’s ability to produce sketches is about equal, and they usually conclude: “I sketch well enough for others to grasp my ideas.” Generative design requires lots of ideas—disposable ideas—not fancy drawings.

Jason Santa Maria says a similar thing in his Pretty Sketchy blog post, in which he declares that sketching is not about being a good artist; sketching is about being a good thinker.
