Decide what you need to learn—and what you do not
Some customer experiences are difficult to discuss. A person may have struggled to pay a bill, felt excluded by a service or encountered a process that brought up painful memories. An interview can help a team understand what happened in the customer journey, but curiosity alone is not a reason to ask for intimate details. Before recruiting anyone, write down the decision the research will inform. Then identify the smallest set of questions needed to make that decision.
For example, if the goal is to improve a cancellation process, you may need to know which steps were unclear and what support was missing. You probably do not need a detailed account of the personal circumstances behind the cancellation. This distinction keeps the conversation focused on the service rather than asking participants to disclose more than they intended.
Make participation an informed choice
An invitation should describe the topic plainly enough for someone to decide whether to take part. Avoid a vague invitation to discuss “your experience” if the conversation may cover debt, discrimination or another sensitive subject. Explain the expected length, who will conduct the interview, whether it will be recorded and how the team plans to use what is shared. Give people a way to ask questions before agreeing.
At the start, repeat the essentials and make clear that participants can decline a question, pause or end the interview. If you offer an incentive, explain that choice without pressuring someone to continue a conversation they want to stop. Be precise about privacy: an interview may be confidential within a defined team, but it is not anonymous if the interviewer knows who the participant is. Do not promise complete secrecy if you cannot provide it.
Ask about the experience without demanding disclosure
Begin with broad, service-focused prompts, such as “Can you walk me through the part of the process you tried to complete?” or “Was there a point when you were unsure what to do next?” Let the participant choose how much context to provide. Follow up on actions, expectations and obstacles rather than pressing for an explanation of private circumstances. A useful follow-up might be “What information would have helped at that point?”
Keep the tone neutral. Questions such as “Why didn’t you ask for help?” can sound accusatory, even when that is not the intent. “What options for help were visible to you?” is easier to answer and more relevant to improving a service. Silence can give someone time to think, but it should not be used to push them toward a disclosure. If a participant becomes uncomfortable, acknowledge it briefly and offer to move on, pause or stop.
Prepare the interviewer and the setting
A discussion guide helps interviewers cover the same core topics while leaving room for participants to describe their experience in their own words. Include an opening explanation, optional prompts and a closing question such as “Is there anything about this process that we have not covered?” Mark questions that should be asked only if the participant has already raised the subject. A short practice run can reveal wording that feels intrusive or confusing.
Choose a setting that gives the participant reasonable privacy and control. For a remote interview, do not assume they are alone or able to speak freely. Ask whether it is still a suitable time, and make rescheduling straightforward. Limit observers, explain who is present and avoid surprise attendees. Interviewers should also know whom to contact within their organization if an unexpected concern arises, rather than improvising promises or support they cannot deliver.
Handle what you learn with restraint
Collect only the personal information needed for the study. Before recording, check that permission covers the recording itself; if it does not, use another agreed way to take notes. Store notes and recordings with access limited to people who need them, and decide in advance when they will be deleted. When sharing findings, remove or generalize details that could identify someone, especially when a distinctive story would be recognizable even without a name.
In analysis, look for patterns in service barriers rather than treating an individual’s account as proof of how every customer feels. Separate what participants said from the team’s interpretation, and note where the sample leaves uncertainty. The most respectful outcome is not the most dramatic quotation; it is a practical change grounded in what people chose to share, without exposing them unnecessarily.
