Product Discovery & User Research
Last reviewed
Correct answer: B. Participants must be actual or likely users of your service
Explanation
The principle — research is only evidence about the people it was collected from.
Why the key is correct — the Service Manual's condition is that For your research to be effective, your participants must be actual or likely users of your service. Actual covers people already using it; likely covers people who would if it existed. Both are claims about the service, which is what makes the findings transferable to it.
Why the others are wrong — availability determines who can be booked rather than who is worth booking. Deep familiarity is not the test and past a point is a liability. And the caution about internal recruitment is scoped to public facing services rather than being a blanket rule.
Remember this — actual or likely users; convenience is not a recruitment criterion.
