  3. Create the smallest flow, sketch, wireframe, prototype, or test needed to answer the question.
  4. Test the design with realistic content, states, and device constraints.
  5. Record what you learned and change the design based on evidence rather than preference.

10 practical examples

  1. Apply Product Discovery to a course website and explain the decision you made.
  2. Apply Product Discovery to a online store and explain the decision you made.
  3. Apply Product Discovery to a banking app and explain the decision you made.
