Rules of UI prototyping I created over time for applications development

1. Rules of UI Prototyping Alex Kouznetsov, PhD [email_address]

2. Up to 5 changes per iteration Iterations are not too small and not too slow

3. 1-2 iterations a day Keep the pace and get feedback

4. Go from A to Z in each prototyping cycle Go wide before going deep. Don't get stuck in deep prototyping of one piece of the app. Make a full circle and return for deeper iteration.

5. Focus on layouts and behaviors Layouts - find and navigate Behaviors - interaction

6. Use samples of real context (instead of generic label) The prototype of a "dog" should "look and walk like a dog"

7. Use samples of real data There is always something to learn from real data

8. Early validation IN and OUT Within the team, across teams and with customers

9. Lo-Fi is OK Don't refine design in prototyping. We don't need high quality design for prototyping

10. Clear communication That's what prototype is good for (plus discovery). Show, explain intention and get a feedback.

11. Support business objectives This is the bottom line. Always keep the business in mind (customers)
