A participant says they returned to a workshop page several times before booking. Your notes say “confusing booking process.” But did they actually say it was confusing?
To write a useful interview follow-up, start with the participant's words, identify what you still do not know, and ask about that gap without supplying an explanation. A good question gives the person room to correct your interpretation.
This guide is for ordinary discovery interviews about how people use a service. The worked example is fictional, including every quotation. It is not customer research or output from a Recolx product.
Separate the note from your interpretation
Before drafting questions, recover the relevant passage in the notes or recording you are authorized to use. Read the question that came before it as well as the answer. A remark can mean something different when detached from what the interviewer asked.
Keep exact words, paraphrases, and your own explanations visibly separate. If your note is a paraphrase, do not put it in quotation marks. If an automated summary supplied the explanation, check it against the source; our summary-checking guide shows why fluent wording is not enough.
For the workshop example, the source note reads:
“I went back to the workshop page a few times before signing up.”
That establishes a reported return to the page. It does not explain why. The person might have been comparing dates, checking details for a friend, or simply postponing a decision. These are possibilities to keep yourself open-minded, not answer choices to read out.
Turn the gap into a question
The research purpose in this example is to understand how someone decides whether a workshop suits them. Three possible follow-ups address different missing details:
Instead of: “Was the booking page confusing?”
Ask: “Could you walk me through your most recent visit to the workshop page?”
The first question introduces a problem the participant has not described. The second asks for an account of an actual visit. If confusion mattered, the person can describe it; if something else mattered, the question leaves room for that too.
Instead of: “Did you go back because you couldn't find the date?”
Ask: “What took you back to the page?”
This leaves the reason open. Once the participant names a reason, ask about that detail. Do not run through your own list of possible causes until one gets a yes.
Instead of: “Would a simpler page make you book faster?”
Ask: “What happened between your last visit to the page and signing up?”
The original question bundles a proposed redesign with a predicted outcome. The revised question asks about the sequence that actually occurred. It may reveal useful context without asking the participant to forecast the effect of an untested change.
The GOV.UK Service Manual's interview guidance recommends open, neutral questions and follow-ups grounded in concrete experiences. It also advises checking a discussion guide with a colleague. The comparisons here are original examples applying that approach, not validated interview results.
Choose the question that serves the research purpose
You do not need to ask all three questions. Start with the one that best addresses the unresolved part of your research purpose, then listen for what remains unclear.
If the participant has already described the last visit in detail, asking them to repeat the whole story adds little. You might instead ask what they meant by a phrase such as “enough information.” Use their wording rather than swapping in “confidence,” “trust,” or another interpretation they did not express.
A brief factual question can also be appropriate. “Which workshop was that?” clarifies the example before a broader question. The goal is not to make every sentence open-ended; it is to avoid pushing an answer or confusing two different events.
For each candidate question, write one private note: What will this answer help me understand? Remove questions that only confirm your preferred design or repeat something already established.
Keep a small follow-up card
Use this working format beside your discussion guide:
- Source: the relevant passage and its location; label quotation or paraphrase.
- Unknown: one specific detail the existing record does not establish.
- Question: wording that lets the participant explain that detail.
- Purpose: the research question this follow-up helps answer.
For our fictional note, the unknown is why the person returned. The question is “What took you back to the page?” The purpose is to understand what information or circumstances shaped the booking decision. No claim about a broken page is needed.
Read the question aloud before using it. If you have joined two questions with “and,” consider asking them separately. A colleague can flag an assumption in the wording, but that check does not prove the question will work equally well with every participant.
Let the answer change your next question
During the conversation, ask one question and give the person time to answer. Do not treat the card as a script you must finish. Their answer may settle a second question or expose a more relevant gap.
Afterward, add the clarification as a dated note linked to the original passage. Preserve what was known at each stage instead of silently rewriting the first record. The same source-linking principle used in a searchable note collection helps another reader check how you reached an interpretation.
If no follow-up is possible, leave the explanation unresolved. An unanswered question is not evidence for the answer you expected.
Try this with one note from your next interview review: underline the participant's wording, write the missing detail, and replace one leading question with a neutral follow-up.
