How to run customer interviews that actually inform your roadmap

Most customer interviews fail in a quiet way: they produce agreeable quotes that make everyone feel validated and change nothing. Good discovery interviews do the opposite — they surface the messy reality of how people actually work, and they feed straight into the decisions your roadmap has to make.

Ask about the past, not the future

“Would you use this?” and “What would you want?” produce polite fiction. People are poor predictors of their own behaviour. Instead, anchor every question in a specific recent event: “Tell me about the last time you tried to do X.” Stories about real past behaviour are the closest thing you have to truth.

Follow the story, chase the friction

Let the customer narrate what happened and stay curious about the moments where things got hard, slow, or confusing. Those friction points are your opportunities. When you hear one, resist the urge to pitch a solution — ask “what did you do next?” and keep pulling the thread.

Capture it so it survives

The insight in an interview is worthless if it evaporates by Friday. Record (with consent), transcribe, and highlight the moments that matter — the exact quote, not your paraphrase of it. A single searchable repository beats a folder of half-remembered notes every time.

Turn quotes into decisions

The last step is the one teams skip: connect what you heard to what you're building. Tag each highlight, group them into opportunities, and link the strongest evidence to the branches of your opportunity solution tree. Now a roadmap decision can point at the customer's own words — and the people who weren't in the room can see the receipts.

A quick checklist

• Recruit for the behaviour you care about, not just anyone willing to talk.
• Open with a specific, recent story rather than a hypothetical.
• Ask “why” and “what happened next” more than you think you should.
• Highlight exact quotes and tag them the same day.
• Link the evidence to an opportunity before it goes cold.

Do this every week and your roadmap stops being a list of guesses and starts being an argument you can win with evidence. That's what Intexo is built for.
