A focus group interview is a qualitative research session in which a moderator guides several participants through a shared topic. Interaction can reveal different experiences, interpretations and reasons for choosing an option.
A small group does not estimate what percentage of an entire market holds an opinion. Use focus groups to develop explanations and hypotheses, then investigate their prevalence or behavioral relevance with suitable additional research.
Choose the method for the question
Method | Useful purpose | Limitation |
|---|---|---|
Focus group | Compare reactions and perspectives on a shared topic | Dominant voices and conformity can influence responses |
In-depth interview | Trace an individual’s experience and decisions | Does not expose the same group interaction |
Survey | Examine the distribution of defined responses | Interpretation depends on questions and sampling |
Choose individual interviews for experiences people may not discuss comfortably with others or for detailed work processes. If you need to know whether people can operate an interface, observation or usability testing may be more appropriate than discussion alone.
Define the decision and recruitment criteria
Replace a broad aim such as “evaluate a new service” with a question such as “identify what information is missing during comparison and why.” Decide which design or communication choices the findings will inform.
For a fictional booking-service study, eligibility might include having booked a similar service in the previous 30 days and being able to describe the comparison process. Recruit for relevant behavior and experience, not demographics alone. Consider whether existing relationships or hierarchy could inhibit discussion.
A small planning example might use four to six participants, but appropriate size depends on the topic, people, time and format. Separate groups may be needed for substantially different experiences. Do not generalize one group’s findings to all customers.
A proposed 90-minute discussion guide
This example investigates booking experiences. Use a moderator and a note-taker, and pilot the questions and timing before the session.
Time | Activity | Example prompt or technique |
|---|---|---|
0–10 minutes | Purpose, recording and ground rules | Explain that different experiences are welcome |
10–25 minutes | Recent experience | Where did you begin looking the last time you booked? |
25–45 minutes | Comparison and difficulty | What was unclear at the point you hesitated? |
45–65 minutes | Review materials or concepts | Write individual first impressions before discussing |
65–80 minutes | Alternatives and decision criteria | Under what conditions would you choose another method? |
80–90 minutes | Missing points and close | What have we not covered, and have we understood correctly? |
Ask neutral questions
Instead of “This screen is convenient, isn’t it?”, ask “What did you expect to do next when you saw this screen?” Rather than relying on “Would you buy it?”, ask participants to reconstruct their last real comparison and decision.
Use participants’ own words when probing. Ask what informed a choice instead of supplying the explanation you hope to hear. Hypothetical intentions can be useful context, but they are not observed purchasing behavior.
Reduce conformity and uneven participation
Collect private initial responses before open discussion. Invite people in turn and ask whether anyone had a different experience. Acknowledge a frequent speaker and make room for others. Silence is not agreement, and a focus group does not need to reach consensus.
Before recording, explain the purpose, recording method, use of the material, access, retention arrangements and how participants can decline participation or a question. Avoid unnecessary personal information and use participant codes in shared notes.
Separate observation from interpretation
Analysis field | What to capture |
|---|---|
Participant and context | Participant code, question and material shown |
Observation or statement | The recorded comment and surrounding context |
Code or theme | A category such as unclear price or booking conditions |
Interpretation | The proposed explanation |
Contradictions or gaps | Different experiences and unanswered questions |
Next check | A revision, another interview or a quantitative study |
Review notes and recordings after the session, preserving both common themes and contrary examples. Four of six participants mentioning something does not justify saying that 67% of customers want it. Frequency of mention is not automatically importance. Explain the circumstances behind the finding and connect it to a concrete change or further test.
