  • 19. Usability Testing
    • Ask representatives of your target audience to perform tasks according to your scenarios
    • Watch them suffer
    • Fix the design rather than explaining it to the participants
    • You don’t need a lab!
    • You can ask the participant to say what buttons they press and describe what is on the screen
    • Ask the participant to show you the screen in-between steps
