A working guide to customer interview practice.
Explore customer interview practice, with practical workflows, a working example and checks for common mistakes.
Explore the guide ↗Customer Interview Studio is a focused resource for founders and discovery researchers, exploring customer interview practice through the work people actually need to perform. For this topic, the workflow is to ask about real situations, probe the existing workaround, and summarise patterns carefully. This guide uses an interview discussion guide to hold the decisions together and examines participant context, question neutrality and consent expectations as distinct quality concerns.
The example involves a researcher speaking with users of a manual booking process; it is an illustrative exercise for this subject, rather than a reported client result. Interview questions should invite accounts of actual behaviour. Ask about a recent situation and its existing workaround; agreement with a proposed solution is weaker evidence than a participant describing the problem unprompted.
Inside the practice
BUSINESS / 10 SECTIONSSet the boundaries for customer interview practice
Start by describing the task that makes customer interview practice relevant now. Use the situation of a researcher speaking with users of a manual booking process to identify the practical question before choosing a method. A concern involving participant context may require different evidence from a concern involving question neutrality.
Keep those questions visible in an interview discussion guide, alongside the intended outcome. The scope of customer interview practice becomes easier to discuss when an agreed requirement is clearly distinguished from an idea that still needs investigation. Before proceeding with customer interview practice, decide whether the current state of consent expectations creates a dependency that needs another person's input.
Use an interview discussion guide as a shared reference for this piece of customer interview practice. The record is especially useful when founders and discovery researchers need to explain why a particular route was chosen. Connect the entry about participant context to the relevant evidence for customer interview practice, rather than copying information without its source context.
Review an interview discussion guide after a meaningful change; an abandoned reference can mislead the next person working on customer interview practice.
Ask about real situations
The first working stage is to ask about real situations. In the example involving a researcher speaking with users of a manual booking process, identify which input is needed before this action can produce a dependable result. Consider how questions about participant context affect the starting conditions for the action to ask about real situations, including information that has not been confirmed.
Record the outcome in an interview discussion guide and explain any limitation before asking somebody to probe the existing workaround. This creates a traceable starting point for customer interview practice, making an incomplete input easier to recognise before it influences the rest of the work.
Probe the existing workaround
Continue by deciding how to probe the existing workaround under the agreed conditions. The handoff from the first stage of customer interview practice should contain the information this action actually requires. Before you probe the existing workaround, inspect question neutrality and identify any assumption that has become doubtful.
If the situation involving a researcher speaking with users of a manual booking process reveals a different requirement, update an interview discussion guide before expanding the work. A visible change decision keeps customer interview practice coherent and helps the next participant understand whether the original scope still applies.
Summarise patterns carefully
05 / 10The third stage is to summarise patterns carefully, bringing the current piece of customer interview practice to an understandable state. Check consent expectations against the agreed purpose of customer interview practice, not merely against a list of completed activities. Use an interview discussion guide to identify follow-up responsibilities and relevant limits.
In the example of a researcher speaking with users of a manual booking process, ask what the receiving person would need before relying on the output. Closing this stage of customer interview practice clearly prevents an unfinished dependency from being mistaken for an accepted result.
Avoid leading participants toward a preferred answer
A specific failure pattern in customer interview practice is leading participants toward a preferred answer. It can create a gap between the appearance of progress and the actual outcome needed by founders and discovery researchers. Check whether participant context was understood before the action began and whether question neutrality was examined by somebody with the relevant context.
Capture the correction in an interview discussion guide, including its effect on consent expectations. The aim is to reduce the opportunity for leading participants toward a preferred answer to recur, while keeping the process proportionate to the work.
Work through a realistic situation
07 / 10Consider a researcher speaking with users of a manual booking process as a small rehearsal of customer interview practice. Write down the request and expected result, then identify who performs the action to ask about real situations. Before moving to the instruction to probe the existing workaround, ask which information the next participant needs.
Use an interview discussion guide to preserve any question the example exposes, especially where participant context is uncertain. Then decide how to summarise patterns carefully without hiding a concern about consent expectations.
Check consent expectations
The review criteria for this guide are participant context, question neutrality and consent expectations. Examine each criterion separately in the context of customer interview practice, because a positive finding in one area does not settle the other questions. For founders and discovery researchers, a useful review records what was examined and how the finding affects the next action.
Connect the evidence to an interview discussion guide, including any limitation in the material available. In the situation involving a researcher speaking with users of a manual booking process, identify which finding would prevent a responsible handover. This approach makes the review of customer interview practice explainable, rather than treating an unexplained approval label as evidence that the task is ready.
Keep the guidance useful after the first pass
Maintenance of customer interview practice should respond to changes in the task, its inputs and its responsible people. Assign an owner to an interview discussion guide and explain which events should trigger another review. A changed assumption about participant context may affect the earlier decision to ask about real situations; a concern about consent expectations may require a new closing check.
Remove obsolete directions from an interview discussion guide deliberately so that earlier versions do not compete with approved guidance. When question neutrality changes, explain whether the instruction to probe the existing workaround needs different inputs or a revised decision.
Begin with one bounded task involving customer interview practice rather than a complete redesign of the surrounding operation. Prepare an interview discussion guide, work through the three actions and inspect the result using the criteria for participant context, question neutrality and consent expectations. Ask someone from the intended audience of founders and discovery researchers to identify a point that still needs clarification.
Compare that observation with the example of a researcher speaking with users of a manual booking process, then choose a specific change worth testing.
