Using Focus Groups
A focus group is a small, guided group discussion used to surface how people actually think and feel about something, in their own words, before you commit money to a decision based on guesswork.
Follow five boxes from one sharp question through to a built-in health warning: this method gives you depth, not proof.
Reach for this when…
- You're about to commit budget to a product or campaign based on internal opinion, not customer reaction.
- Survey data tells you what people think but not why.
- You need to understand the language and reasoning customers actually use, not the language your team assumes.
How to run it
- Define one specific question you need the group to help answer, not 'general feedback'.
- Recruit a small, genuinely representative group of six to ten people, not just easy-to-reach customers.
- Write open-ended discussion questions and let a neutral facilitator run it, not you.
- Record and analyse for themes and language, not just for agreement or disagreement with your idea.
- Treat the output as depth, not proof - pair it with a wider check before betting real money on it.
A worked example
Situation. Lin Yu-Ting ran product at Beishan Gear, an outdoor equipment retailer in Taichung, Taiwan, planning a new lightweight tent line based entirely on what the design team liked.
Applied. She ran two focus groups of experienced backcountry hikers, asking open questions about pack-weight trade-offs rather than showing them the design and asking if they liked it.
Result. The groups revealed hikers would trade weight for durability far more than the design team assumed, the opposite of the internal brief. Beishan redesigned the fabric spec before tooling was ordered.
The catch
A handful of vocal participants can dominate the room and get mistaken for consensus, and people's stated preferences in a group setting often diverge from what they'd actually do with their own money. It's a tool for depth and hypothesis generation, not for statistically validating a decision.
If one participant did most of the talking, you ran an interview with an audience, not a focus group.
