Moderated usability testing
What is moderated usability testing?
Moderated usability testing is a research method where a facilitator guides participants through tasks on a product while observing their behavior, asking probing questions, and noting points of confusion or success.
How it works
A facilitator gives representative tasks, observes participants and asks neutral follow-up questions. Avoid coaching the participant through the interface when measuring unaided performance. If intervention is necessary, record it and distinguish assisted from unassisted results. Sessions can be in person or remote.
Applied example
A health-enrollment test could reveal confusion about a term such as dependent. Researchers could investigate the misunderstanding and test a clearer explanation that matches the plan’s actual eligibility rules. The facilitator might ask, “What does that word mean to you here?”
Why it matters
Moderated testing permits observation and follow-up within the same session. Its quality depends on task design, participant selection and neutral facilitation.
