# Focus Group Guide: Method, Agenda, and 20 Open-Ended Questions

A useful focus group is not designed to secure quick agreement. It creates a discussion in which participants can clarify, challenge, and extend one another's experiences—while preserving enough evidence to separate genuine convergence from disagreement.

The method rests on three principles: begin with genuinely open-ended questions, protect individual responses before group influence takes hold, and analyze interaction without treating a few voices as statistical truth.

## What is a focus group—and what is it not?

A focus group is a moderated group interview. Its defining feature is not simply that several people answer questions in the same room: participants also respond to the experiences, language, and disagreements introduced by others.

That interaction helps explore **why** something happens: how a need is described, what makes an idea credible, why a process breaks down, or when an opinion changes. It produces richer qualitative material than a predefined list of options because it can preserve participants' vocabulary, context, exceptions, and contradictions.

A focus group does not measure how common an opinion is in a population or estimate market size. A lively discussion is not a representative sample. The UK government's qualitative research guidance frames focus groups as a way to understand views and experiences through a group dynamic that differs from an individual interview ([GOV.UK](https://www.gov.uk/guidance/focus-group-study-qualitative-studies)).

## When should you use a focus group?

Use this method when interaction between participants is part of the research question:

- to hear the language people spontaneously use around a problem;
- to explore reactions to a concept, service, or experience;
- to surface adoption conditions, reservations, and objections;
- to observe how people argue, qualify, or revise a view;
- to develop hypotheses for a broader survey.

Choose a [semi-structured interview](https://www.harmate.com/en/blog/semi-structured-interview-guide-method-steps-and-15-examples) when the experience is intimate, sensitive, or strongly shaped by hierarchy. Methodological reviews warn that some subjects are difficult to disclose in a group and that power dynamics can suppress participation ([Busetto et al., 2020](https://pmc.ncbi.nlm.nih.gov/articles/PMC7650082/)).

A [World Café](https://www.harmate.com/en/blog/world-café-method-90-minute-agenda-and-15-facilitation-questions) serves a different purpose again: ideas move between tables to create a collective harvest. A focus group remains centered on a research question and on understanding the discussion it generates.

## How to prepare a focus group in 7 steps

### 1. State the decision you need to inform

Before writing a discussion guide, complete this sentence: “After this research, we need to decide whether…” This prevents a collection of interesting questions that never affect a decision.

### 2. Define what the group can reveal

List your qualitative unknowns: reasons, situations, language, objections, conditions, and contradictions. If you only need a percentage, a focus group is the wrong instrument.

### 3. Recruit people with relevant experience

Participants need direct experience of the topic. Similarity can make disclosure easier; too much similarity can also reduce the exchange of different views. Composition should follow the research question rather than a universal recipe ([Comparative focus group methodology, 2019](https://pmc.ncbi.nlm.nih.gov/articles/PMC6791916/)).

Unless hierarchy is the subject of the research, avoid mixing participants with strong authority relationships. If that cannot be avoided, collect individual input first and document the limitation in the analysis.

### 4. Set group size and duration

Six to eight participants often works well, but it is not a universal standard; smaller groups may suit complex topics. GOV.UK describes one to two hours as common. The right format gives each person enough room to contribute without exhausting the group.

### 5. Build a funnel-shaped guide

Start with concrete experience, then move toward reasons, tensions, and choices. Keep four to six core questions; use the remaining formulations as probes. Twenty examples do not mean twenty mandatory round-robin questions.

### 6. Plan the record

With participants' consent, arrange recording or structured notes, an observer where useful, and a convention for distinguishing speakers. Capture silence, expressed agreement, objections, and changes of mind as well: interaction is part of the data.

### 7. Test the guide

Ask someone close to the intended audience to interpret each question without being told the answer you expect. A good prompt should be understandable without boxing in the response.

## A 90-minute focus group agenda

| Time | Sequence | Purpose |
|---|---|---|
| 0–10 min | Welcome, consent, and ground rules | Create a setting where disagreement is allowed |
| 10–15 min | Individual written reflection | Capture initial responses before group influence |
| 15–30 min | Concrete experiences | Start from events rather than abstract opinions |
| 30–55 min | Reasons, barriers, and exceptions | Explore what explains differences |
| 55–70 min | Productive tension | Surface reservations, contradictions, and edge cases |
| 70–80 min | Consequences and next steps | Identify what should be tested, changed, or verified |
| 80–88 min | Final individual round | Give space to voices heard less often |
| 88–90 min | Close | Explain how the material will be used |

The short writing period is not a replacement for discussion. It preserves an initial response that the group can later enrich or challenge. Research on focus group practice also describes activating techniques such as participant-generated cards ([Tausch and Menold, 2016](https://pmc.ncbi.nlm.nih.gov/articles/PMC5342644/)).

## 20 open-ended focus group questions

Treat these prompts as starting points. Select the ones that serve your decision and replace generic wording with a specific situation.

### Questions that begin with experience

1. **Tell us about the last time you encountered this problem.**
2. **What were you trying to accomplish at that moment?**
3. **What did you do first, and what happened next?**
4. **What surprised you about the experience?**
5. **What words would you use to explain it to someone unfamiliar with the topic?**

### Questions that explore causes and barriers

6. **At what point does the situation become difficult?**
7. **What genuinely helps you move forward?**
8. **What have you already tried without getting the result you expected?**
9. **What is missing from the current options?**
10. **When does this problem disappear or become less important?**

### Questions that surface differences

11. **What in the discussion so far matches your experience?**
12. **What does not match your situation at all?**
13. **Who might experience this differently, and why?**
14. **What important point are we at risk of oversimplifying?**
15. **What example best challenges the apparent consensus in this room?**

### Questions that prepare the next decision

16. **Which change would create the most value in your situation?**
17. **What would make you try this option—or reject it?**
18. **Which promise would sound credible, and which would make you suspicious?**
19. **What would need to be verified before a decision is made?**
20. **What should we have asked to understand your point of view better?**

Open-ended prompts surface reasons, language, and unexpected cases. Closed-ended questions can later measure the reach of a stable hypothesis; they should not replace exploration while the relevant categories are still unknown. See our guide to [open-ended questions](https://www.harmate.com/en/blog/open-ended-questions-get-actionable-data-without-bias) for a deeper explanation.

## How to prevent false consensus

A focus group can appear to agree simply because the first speakers set the frame, some people speak more often, or others avoid challenging authority. Methodological reviews explicitly recommend watching for groupthink and power dynamics ([Busetto et al., 2020](https://pmc.ncbi.nlm.nih.gov/articles/PMC7650082/)).

### Capture an answer before discussion

Ask each participant to note one experience, objection, or choice before the first exchange. This creates a record that does not yet depend on the dominant argument.

### Do not reward the fastest answer

Leave a few seconds after a contribution before probing. Explicitly invite a different experience without assigning one person the permanent role of dissenter.

### Separate convergence from agreement

Two people may use the same word for different realities. Ask for a concrete example before deciding that a theme is shared.

### Actively seek the case that resists

Ask: “When would this conclusion be wrong?” A well-documented exception may change the decision more than a majority of shallow reactions.

### End with a final individual round

Ask what is still missing from the provisional summary. This is not a vote; it is a chance to recover nuance that collective discussion may have flattened.

## How to analyze a focus group without flattening disagreement

Analysis is not a count of supporters and opponents. It should connect four levels:

1. **source excerpts**, with their context;
2. **codes**, describing what is expressed;
3. **themes**, organizing patterns of meaning;
4. **implications**, which remain interpretations to be discussed.

Interaction also matters in focus group data: who builds on whose point, where disagreement appears, which example moves the conversation, and what silence follows a proposal. A systematic analysis should consider this group dynamic rather than merely lining up isolated quotes ([Sharpening the focus, 2018](https://pmc.ncbi.nlm.nih.gov/articles/PMC6016125/)).

Thematic analysis offers a flexible framework for moving from a corpus to patterns of meaning, provided the analyst makes their interpretive choices visible ([Braun and Clarke, 2006](https://doi.org/10.1191/1478088706qp063oa)). For more formal research, the [COREQ checklist](https://www.equator-network.org/reporting-guidelines/coreq/) covers the research team, setting, collection, analysis, and reporting of interviews and focus groups.

An operational deliverable should retain at least the theme, the source excerpts supporting it, counterexamples, the population concerned, limitations, and the decision the finding can inform. Our guide to [analyzing 200 open responses](https://www.harmate.com/en/blog/analyzing-200-open-responses-without-bias-a-method-for-actionable-decisions) explains this evidence trail in more detail.

## Moving from exploration to measurement

Focus groups are often useful for discovering the right categories before measuring them. A coherent sequence is:

1. explore experiences through open-ended questions;
2. form hypotheses and categories from participants' language;
3. design closed-ended questions to compare or estimate frequency;
4. retain one or two open-ended prompts to detect what the quantitative frame misses;
5. interpret measured results alongside the qualitative explanations.

Qualitative research is not an imprecise version of quantitative research. It discovers reasons and categories; quantitative methods then measure what has become sufficiently defined.

## What a tool can support

A tool can help collect individual reflection before the session, bring together written responses across several groups, surface themes, and retrieve the excerpts supporting each finding. It should not decide that a disagreement is negligible or turn a summary into an automatic verdict.

Harmate's [Open Questions](https://www.harmate.com/en/product/open-questions) page shows a workflow from source excerpts to themes and then to evidence explicitly selected by the team. It can complement a focus group by preparing contributions or structuring post-session analysis; it does not replace moderation or the judgment of a researcher or consultant.

## Focus group checklist

- Can you state the decision to inform in one sentence?
- Does group interaction add something an individual interview would not?
- Do participants have direct experience of the topic?
- Have authority relationships been avoided or explicitly addressed?
- Are the core questions open-ended and neutral?
- Does individual reflection precede discussion?
- Do the announced rules make disagreement safe?
- Can the record take you back to the original wording?
- Does the analysis plan include interaction, exceptions, and limitations?
- Does the next step distinguish exploration from measurement?

## Frequently asked questions

### How many people should be in a focus group?

Six to eight often works well, but the number depends on topic complexity, desired diversity, and available time. A smaller group in which everyone contributes is more useful than a large group dominated by a few voices.

### How many focus groups do you need?

There is no universal number. Run multiple groups when you need to compare audiences or check that findings do not depend on one group dynamic. Stop according to the research objective, diversity covered, new information, and study constraints—not a supposedly magic threshold.

### Can you run a focus group online?

Yes. Reduce group size if turn-taking becomes difficult, test the technology, define speaking rules, and offer an individual written channel. Digital access and confidentiality should be documented as limitations.

### Can a focus group validate a product idea?

It can reveal reactions, use contexts, objections, and adoption conditions. It cannot by itself prove market demand or purchasing behavior. Use the findings to design complementary tests and measurements.

### Should a focus group aim for consensus?

No. Consensus may be a finding, but it is not the default objective. An explained divergence tied to a specific situation often adds more decision value than agreement reached too quickly.

## Key takeaway

A good focus group does not manufacture an average opinion. It creates conditions in which experiences can respond to one another without erasing initial voices, then preserves the excerpts, interactions, and limitations needed for interpretation.

Start open, look for what resists consensus, and move to measurement only after you understand what you are actually trying to compare.
