What is a Focus Group Interview (FGI)?
"A beginner-friendly guide to Focus Group Interviews (FGI) with practical examples and core principles."
When diving into early-stage business planning or customer research, you will inevitably come across the term FGI. While it often sounds like dry academic jargon, the core concept is remarkably simple.
💡 FGI in a Nutshell "Gathering 5 to 6 people who share similar traits or pain points in one room, and setting the stage for a casual group conversation to uncover their true, unfiltered thoughts."
If a 1-on-1 interview is like a 'microscope' that deeply examines a single person's life and experiences, an FGI is more like a 'chemical reaction'—multiple people resonating with each other's stories to reveal hidden needs.
🎯 Why Interview in a Group? (The "Me Too!" Effect)
If you bluntly ask someone, "What are you struggling with?", most people freeze up and give generic answers. However, when they chat with peers who share similar experiences, their real problems naturally bubble to the surface.
If someone casually mentions, "Isn't it so annoying to do your makeup before commuting?" the person next to them might chime in, "Exactly! That's why I just do my makeup on the bus." Through this chain reaction of relatable dialogue, product managers can discover the 'real problems' (Core Pain Points) that even the customers themselves hadn't consciously recognized.
🍱 A Practical Example Even Beginners Can Understand
Imagine you are designing a "Cost-Effective Daily Lunch Box Subscription Service for Office Workers." You gather five office workers in their 20s and 30s—your target audience—and conduct an FGI.
🗣️ Moderator (You): "How do you usually handle lunch on workdays?"
👩🏻💻 Worker A: "Eating out is too expensive lately, so I've been packing my own lunch to save money." 🧑🏻💻 Worker B: "I agree, I pack mine too... but honestly, prepping it in the morning is such a hassle." 👨🏻💻 Worker C: "Prepping is one thing, but coming home tired and having to wash that smelly lunch box is the absolute worst." 👩🏻💻 Worker A & B: (Nodding enthusiastically) "Yes!!! Doing those dishes is terrible!"
💡 The Insight Initially, you might have assumed that the 'high cost of eating out' was the biggest problem. But through the FGI, you discovered that 'the sheer annoyance of washing the dirty containers' is actually a much more severe pain point. 👉 Pivoting the Strategy: Instead of just delivering cheap lunches, you should pivot the service to offer eco-friendly disposable containers or a container pick-up/cleaning service.
🚨 3 Golden Rules for Running an FGI
- Moderators: Close Your Mouth, Open Your Ears.
- The customers are the main characters of an FGI. The moderator should never dominate the conversation or try to teach the participants. Drop light, open-ended questions to keep the flow going, and then step back.
- Never Ask About the Future. Ask About the Past. (Captain Cucha's Advice ⛵️)
- ❌ "If we build this feature, would you pay for it?" (People are polite; they will say yes just to be nice.)
- ⭕️ "What specific actions have you taken recently to solve this problem? Have you ever spent money or time trying to fix it?"
- Beware of the Loudest Voice in the Room.
- The fatal flaw of group interviews is that the entire room's opinion can be hijacked by one overly vocal or opinionated participant. The moderator must ensure everyone gets a turn by actively pulling in the quieter participants: "What was your experience like last week, Sarah?"
📝 Summary: When Should You Use an FGI?
- Use it when you want to explore new ideas, or quickly gauge the diverse reactions and consensus of a specific group regarding a certain topic.
- Conversely, when dealing with highly personal or sensitive topics (e.g., personal finances, medical history), a 1-on-1 interview is far more effective than an FGI.
