01
Write down what you actually noticed
Record the observation in plain language before explaining what you think it means. In the appointment example, the friend used several notes; that does not yet tell you why, whether it was difficult or whether a different tool would help. Place those interpretations beside the observation as open questions. This small separation makes the conversation easier to prepare. It also leaves room for an explanation you did not expect, such as the notes serving different people or holding information outside the booking task.
02
Invite a recent account instead of agreement
Ask the person to describe the last time they arranged a similar appointment, including what they used and where they needed to pause or check something. Follow up on details they mention rather than leading with the proposed product. A question about what happened is more useful for this purpose than asking whether your idea sounds good. Keep the conversation proportionate and obtain permission before recording it. Notes should distinguish the person’s account from your interpretation, especially when a detail seems to support the original hunch.
03
Choose the next question from what remains unclear
Afterward, summarise the experience and identify which parts of the initial assumption changed. Perhaps the appointment itself was simple, while sharing the details afterward took effort. That suggests a different question to explore. Record what you still do not know and whose experience could help clarify it. Avoid turning a single account into a claim about every potential customer. The result is a more specific research direction: an observation, a grounded account and a next question that earns its place in the project.
