FORMAL USABILITY STUDY BEST PRACTICES
FOUR QUESTIONS TO INCLUDE DURING SCRIPTED USABILITY TESTS:
Show the participant a screen from the prototype and ask:
1. Can you describe what they are looking at?
Then before the participant takes action with the prototype, ask:
2. What would you do next to complete your task?
3. What would you expect to see?
After the participant takes action with the prototype, ask:
4. How does this match your expectation
Asking these questions around each task should help you identify most of the usability issues with your website.
