Customer interviews that change a decision, not just confirm an idea

A practical conversation guide and evidence sheet for deciding what to test before you build.

A gold piece completes a section of a dark stone arch, an editorial metaphor for adding evidence to a decision.

You do not need another person to say your idea sounds promising. You need to understand what happens when the problem appears and how they deal with it. A useful conversation leaves you with a clearer decision, even if that means changing your intended customer or dropping a feature.

This field guide offers a short interview structure and an evidence sheet. An interview does not establish demand on its own. It helps you design the next test of actual behavior.

Write the decision before recruiting interviewees

Imagine you are considering a tool for preparing sales proposals. This is a hypothetical example, not a Ramen Founders customer success story. Asking whether people like the idea provides little direction. Investigating how an independent consultant prepares a proposal under time pressure gives you a situation to explore.

Write down the person and context, the episode you want to reconstruct, and the decision you will make afterwards. You might be deciding whether an initial prototype should help produce one draft rather than manage an entire sales process. Leave room for an unfavourable answer.

Speak with people who have experienced that situation recently. Friends and contacts can introduce you to them, but friendliness is not a substitute for relevant experience. A small sample can uncover questions and patterns; it does not automatically represent a market.

Reconstruct an episode before pitching your solution

Eric Migicovsky's Startup School guidance focuses on specific situations and remedies people have already tried. Our practical suggestion is to turn the conversation into a sequence you can examine afterwards.

Allow an answer to finish before explaining what you think it means. If someone says a task takes forever, ask for an episode that makes that description concrete. If they cannot recall one, preserve the uncertainty instead of filling the gap with the story you hoped to hear.

Keep observation separate from interpretation

After each interview, complete a five-field evidence sheet. You need a useful record, not an elaborate transcript.

In the proposal example, seeing someone reuse an old document is an observation. Concluding that they need a new platform is an interpretation. A clearer template might be enough. Or the real delay might be obtaining information from their client.

Do not put another customer's information into an AI tool without permission. Remove identifiers when organising notes and retain only necessary context. You do not need to record an interview to learn from it; agree in advance if recording would help.

Agree on a proportionate next step

A friendly interview can justify further investigation. It does not establish willingness to buy. The next step could be reviewing an anonymized example, observing a task or agreeing to a bounded trial. Explain the actual offer and choose a commitment proportionate to what you have learned.

If someone declines, respectfully explore what makes the next step unsuitable. It could be low trust, another priority or a problem that matters less than you assumed. A refusal is information, not automatically an objection to overcome.

Your exercise for this week

Write one unresolved decision. Arrange three conversations as an initial learning round, not a scientific validation threshold. Complete the evidence sheet after each. Compare recurring behavior, contradictions and remaining gaps.

Then record a decision: narrow the segment, try a manual delivery or investigate another problem. Include the evidence that would make you reconsider.

Ramen Founders is a place to turn practical tools into useful work. Share the context of your project and one decision that changed after listening to someone. Protect the person's identity when describing the conversation. You can also explore our free founder tools.
