Focus groups, tested.
Also called: Concept testing · Direction testing · Reaction sessions · Small-group feedback
Putting a concept or two in front of small groups of real customers to read their genuine reactions before you commit to a direction.
Show a concept to a handful of real users and watch how they react. Useful for spotting strong feelings early, useless for predicting sales. The traps are groupthink, the loud voice, and people being polite. Design the session to fight all three.
What testing with focus groups is
A focus group is a small set of real customers, usually six to eight, in a room with your concept and someone asking careful questions. You are not running a vote and you are certainly not running market research with a sample size that means anything. You are reading reactions: where people lean in, where they go quiet, what they argue about, and what they politely fail to mention.
Done honestly it tells you things a spreadsheet never will. Done as theatre, which is most of the time, it tells you what people think you want to hear over biscuits and lukewarm coffee. The difference is entirely in how the session is run, not in the method itself.
What it is good at, and what it is not
- Good at: surfacing strong reactions you didn’t expect, hearing the language real users reach for, and catching a direction that quietly dies in the room.
- Not good at: predicting what people will buy. What someone says in a friendly room and what they do with their own £149 are different events, and the gap is where most product optimism goes to perish.
- Dangerous at: giving a committee the comfort of “we tested it” when all they really tested was whether eight strangers would be rude to your face. (They won’t.)
So treat a focus group as a signal detector, not a decision-maker. It tells you where to look harder. It does not get a vote.
Running a session that gives real signal
The whole craft is fighting three forces: groupthink, the dominant voice, and ordinary British politeness. Here is how that played out when we put the proofing-box concept in front of small groups of real bakers, alongside two directions we ended up rejecting.
The structure did the work. The written-answers-first rule meant we read what people genuinely thought before the room had a chance to converge on the most confident voice. That single mechanic separates a focus group worth running from a comfortable chat.
- One confident voice sets the room and everyone nods along.
- Leading questions that beg for a yes (“you’d love this, wouldn’t you?”).
- The team in the room, beaming, while people stay kind.
- “Would you buy it?” answered yes by people risking nothing.
- Silent written reactions captured before anyone speaks.
- Neutral facilitator asking open, non-leading questions.
- The team out of eyeline, watching, not performing.
- Reactions read for surprise and conflict, not headcount.
The left column is what most people mean by a focus group, and it is why the method has a poor reputation. The right column is the same method run with discipline, and it earns its place. The choice is yours, not the method’s.
How it fits the bigger picture
Test With Focus Groups is the last activity of Stage 03 Innovate. It comes after the concepts and directions Innovate generated, and it hands a tested, narrowed set of directions into Stage 04 Evaluate, where they meet competitors, market sizing, and the harder commercial questions that a friendly room can never answer.
What it can do
It catches strong reactions early and cheaply, while a concept is still on a board and cheap to change. It surfaces the language real users reach for, kills directions that quietly die in the room, and tells you where to look harder before you spend real money.
What it can’t do
It can’t predict sales, and it can’t replace evidence of behaviour. Eight friendly people saying “yes, lovely” is not a market. The proper commercial test belongs to Stage 04 Evaluate; the focus group only points you at the questions worth asking there.

Try it yourself
Recruit six to eight real target users who don’t know each other. Show your concept, plus one or two directions you’re genuinely unsure about. Capture written reactions before anyone talks. Use a neutral facilitator and keep the team out of eyeline. Then read the session for surprise and conflict, not for headcount. You’re hunting signal, not applause.

Project notes: the room that liked the silence

Two rooms of bakers, three concept boards, and the moment the no-app stance stopped being a gamble and started being a feature.

Dan and Anna Hartley were nervous about the no-app decision. The whole market was bolting Wi-Fi onto kettles, and here we were proposing a £149 ceramic box with a single dial. So before committing, we ran two focus groups of six serious home bakers in Manchester, recruited through the Sourdough School audience.
What we put on the table
Three boards, deliberately. The heated ceramic box holding 26°C overnight, no app. A connected version with a phone readout and alerts. And a cheap plastic version we fully expected to lose, included so the room had something to push against rather than just a single thing to be polite about.
The mechanic that saved us
I insisted on written answers before any talking. Each baker wrote what each concept was for, who it wasn’t for, and what they’d pay, in silence, before a word was spoken. In the first group one confident chap clearly fancied the app version and would happily have led the room there. The written sheets, collected first, told a quieter and truer story.
On paper, the app board drew careful admiration and not much warmth. “Another thing to charge.” “I’d forget to connect it.” The no-app box, by contrast, drew visible relief: “Oh good, it just works.” The plastic version was dismissed as a gadget without anyone needing to be unkind about it.
What we did with it
We did not treat twelve bakers as a market. What we took from the room was a sharpened question for Stage 04: the no-app stance was not the liability Dan feared, and might be a genuine reason to choose the product. That was worth pressuring properly with real commercial evidence later, and it was. (The cheap plastic board, for what it’s worth, never recovered from being called “a bit of a gimmick” by a very polite woman in the second group.)
