Up to 5 changes per iteration

Iterations are not too small and not too slow

Page 3: Rules of UI prototyping

1-2 iterations a day

Keep the pace and get feedback

Page 4: Rules of UI prototyping

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.

Page 5: Rules of UI prototyping

 Focus on layouts and behaviors

Layouts - find and navigateBehaviors - interaction

Page 6: Rules of UI prototyping

Use samples of real context (instead of generic label)

The prototype of a "dog" should "look and walk like a dog"

Page 7: Rules of UI prototyping

Use samples of real data

There is always something to learn from real data

Page 8: Rules of UI prototyping

Early validation IN and OUT

Within the team, across teams and with customers

Page 9: Rules of UI prototyping

Lo-Fi is OK

Don't refine design in prototyping. We don't need high quality design

for prototyping

Page 10: Rules of UI prototyping

Clear communication

That's what prototype is good for (plus discovery). 

Show, explain intention and get a feedback.

Page 11: Rules of UI prototyping

Support business objectives

This is the bottom line. Always keep the business in mind

(customers)
