Prototype & Test

Objective

Section titled “Objective”

Create a realistic prototype and test it with users to validate (or invalidate) the solution designed during the sprint.

User Test Flow

Section titled “User Test Flow”
  • Break down the user journey into 4 to 6 key steps.
  • Each team member proposes their version → read aloud → vote on the best flow.
  • Helps align the team before moving on to the storyboard.

Storyboard

Section titled “Storyboard”
  • Visualize the user experience, step by step.
  • Each screen is drawn in a frame (paper or digital tool).
  • Goal: highlight the essential interactions to prototype.
  • The team collaboratively identifies key or complex moments in the journey.

Prototyping

Section titled “Prototyping”
  • Build a realistic experience for testing.
  • Recommended tools: Figma, Adobe XD, InVision, ProtoPie
    (or PowerPoint / Keynote if skills are limited).
  • Task distribution: designers (UI), writers (content), others (images, test planning).
  • Focus on functionality, no need for a pixel-perfect result.
  • Prepare a test script (objectives, tasks, questions).

User Testing

Section titled “User Testing”
  • Conducted with 5 representative users.
  • 3 main goals:
    1. Observe how the prototype is used
    2. Collect feedback
    3. Present findings to stakeholders

“Five-Act Interview” Method (Jake Knapp)

Section titled ““Five-Act Interview” Method (Jake Knapp)”
  1. Welcome
  2. General questions
  3. Show the prototype
  4. Tasks to complete
  5. Debrief and impressions

⚠️ Ask for consent if the session is recorded.

Collecting Feedback

Section titled “Collecting Feedback”

Feedback Wall

Section titled “Feedback Wall”
  • Board with 1 column per tester, 1 row per question.

Voltage Control Scorecard

Section titled “Voltage Control Scorecard”
  • Collaborative spreadsheet with short responses (✔️ / ❌ / ?).

Key Takeaways

Section titled “Key Takeaways”
  • The user is central: every choice should meet real user needs.
  • The sprint promotes collaboration, efficiency, and quick decision-making.
  • Testing is essential, even after the sprint.
  • The prototype is a validation tool, not a final version.

Summary

Section titled “Summary”
  • Prototyping brings a shared vision to life.
  • User testing quickly reveals what works and what doesn’t.
  • 5 testers are enough to catch most usability issues.
  • A sprint can save months of design and development time.
