Question Asking Protocol
What is Question Asking Protocol?
During a usability test, besides letting the test users to verbalize their
thoughts as in the thinking aloud protocol, the testers prompt them by asking
direct questions about the product
Why Use it?
Question Asking Protocol is used n order to understand the users mental
model of the system and the tasks, and where they have trouble in understanding
and using the system. This is a more natural way than the thinking-aloud
method in letting the test user to verbalize their thoughts.

(same as think aloud)
- Also ask them pointed, direct questions about the product; for example,
"How would you send the email message?"
