Customer interviews without leading people
Questions, structure, and synthesis methods for customer discovery interviews that produce evidence instead of polite agreement.
Ask about the past
People are unreliable predictors of hypothetical behavior, but they can describe what they already did. Ask about the last time the problem occurred and keep returning to concrete details.
Replace ‘Would you use this?’ with questions about triggers, actions, alternatives, costs, approvals, and outcomes.
Keep in mind
- Talk less than the participant.
- Do not pitch until the learning portion is complete.
- Capture exact evidence and your interpretation separately.
Use a consistent guide
A repeatable structure makes interviews comparable: context, last occurrence, current workflow, consequences, alternatives, decision process, and closing referrals.
Follow interesting details, but ask the core questions in every session. Immediately note surprises, contradictions, and assumptions that changed.
Synthesize across conversations
Do not count positive adjectives. Tag repeated situations, behaviors, constraints, and switching triggers. Segment responses when patterns differ by role or context.
After each batch, update the problem statement and decide which uncertainty deserves the next interview. Research is useful when it changes a decision.
