How to sketch to share design ideas

Groups of participants that are new to the Five Sketches™ design process may need help to boost their confidence. That’s because people mistakenly believe sketching has to be artistic and beautiful. In fact, it’s the opposite. Sketches are merely meant to communicate ideas—lots of ideas, in our case. Sketching is not about the quality or fidelity of the image, because higher fidelity means it took more effort, and people get attached to that effort, even when the idea isn’t so great.

Rationally, would you want to keep a mediocre idea simply because it took a long time to sketch? Or would you rather have a dozen rough ideas to choose from, so you could pick and choose the best parts and mash them together, into something better?

Five Sketches™ sketching is about quickly capturing and sharing many ideas so they can be understood and re-used by others.

How a sketch communicates well

During the Five Sketches™ process, a sketch must be able to communicate to people sitting across the table from you after you post your sketch on the wall behind you. And it must communicate on a wall covered in competing sketches.

Here’s how to ensure a sketch can communicate.

Sketch quickly, on large paper with fat-nib pens, add a title, and use red for actions
  • Sketch on large paper that’s cheap—because many of your ideas will be short lived. Tabloid paper (11.5 × 17 inches) or A3 paper (30 × 42 cm) is best because it’s big—but still fits an office photocopier for later scanning.
  • Sketch only enough detail to communicate the idea. Sketching is about capturing ideas and thinking through ideas in low fidelity. Excess detail adds clutter that makes it harder for others to read the sketch.
  • Use fat-nib markers. This ensures a sketch is legible from ten feet away, and discourages excess detail.
  • Add a descriptive title—so not “Sketch 1” but “List each product beside its photo” for example.
  • Be careful with colour. Reserve red markers only for labelling the user actions and system responses, if the actions need calling out.

Exercises: Learn that working quickly works well

As facilitator, you need to reassure the participants that they can sketch. Give each group member some large sheets of paper and some fat-nib markers, as described above.

To start the exercise, ask the participants: “Use 10 seconds to draw me a house. Start now.” Count aloud from ten to zero, and then ask them to stop. Have people look at their neighbour’s sketches. Don’t draw attention to unusual details. Instead, ask them to point out the common elements across all the sketches: a pointed roof? a door? a window? a chimney? Do sketches still communicate the idea of house effectively when some of the common elements are missing?

Next, ask everyone to carry on, in quick succession: “In 8 seconds, draw an airplane.” And then: “In 6 seconds, draw a baby.” And then: “In 4 seconds, draw a ship,” and “In 2 seconds, draw a car.” After these four sketches, ask them to point out the common elements of airplanebabyship, and car. Is there a lower limit to how fast people can sketch and still communicate an idea clearly, to others?

Sketch quickly, with only the most essential details. Which details could this sketch do without while still conveying the idea of “a boat”?

Now ask people to take 15 seconds each to draw: a mobile phone, a map app on a tablet, an airport check-in kiosk, and a self-operated grocery check-out station. If your team needs to work with a specific type of object, ask them to sketch that in 5 or 10 seconds. What is the minimum number of lines that still communicates that object effectively?

Display a news website, such as bbc.com/news. Ask people to sketch the site’s home page—but generically, without today’s specific content. Give them 30 to 45 seconds. Then discuss with the group how they sketched the following elements: a heading, a paragraph of text, a photo, a link, a button, a tab. How much detail is sufficient? Would different colours help, such as blue ink for links, and black ink for everything else?

Using the sketch of news website, ask participants to add to it:

  • Use a red marker to label potential user actions on the page.
  • Add a title to the sketch—something descriptive, not “sketch 1” though “sketch 5” but “List latest global news first” or “List local news for detected location” and so on.

Now tell them: “You have all the skills you need to sketch five distinct ideas that address our problem statement.”

“I want to use my computer”

The majority of people who work in software development would prefer to produce “sketches” with the help of their computer. Here’s why this is a bad idea during the idea-generation phase of a design process.
