Practice active listening without leading the participant
This method helps uncover not just what users do, but why they do it, providing context that quantitative data alone can't capture.
Observing Without Interfering
While it's tempting to jump in and help when a participant struggles, resist the urge. The goal is to observe natural user behavior, which includes how they navigate challenges or confusion.
Best practices for non-interference:
Prepare a script to maintain consistency across sessions
Use neutral language when giving instructions
Avoid leading questions or gestures
If a participant asks for help, redirect with "What would you do if I weren't here?"
Remember, every moment of struggle is valuable data that can inform improvements to your product's design.
Asking Relevant Questions
The questions you ask can make or break your usability test. Craft questions that elicit meaningful responses without leading the participant.
