On Monday, you and your team defined the challenge and chose a target. On Tuesday, you’ll come up with solutions. The day starts with inspiration: a review of existing ideas to remix and improve. Then, in the afternoon, each person will sketch, following a four-step process that emphasizes critical thinking over artistry. Later in the week, the best of these sketches will form the plan for your prototype and test. We hope you had a good night’s sleep and a balanced breakfast, because Tuesday is an important day.
