Customer Research Task
Know when another customer interview will add useful evidence
Interviews are starting to repeat, but an arbitrary count cannot show whether the team missed a segment or contrary case.
“This is costing me interview time without a clear test for useful new information.”
The result you need
A documented decision identifies the remaining gap and explains whether another round can address it.
What is happening now
Where the work gets stuck
An entrepreneur in residence, founder, or operator is running repeated qualitative interviews.
- When it starts
- Themes repeat and the worker must stop, change the sample, or continue.
- What makes it difficult
- A fixed interview count ignores the research question, sample variation, analysis method, and unresolved evidence.
- What progress looks like
- The review tracks new themes and contrary cases by round and names missing segments that could change the decision.
What to try next
Review whether another interview round will help
Replace a fixed interview target with an explicit review of new information, sample variation, and unresolved evidence.
Before you act
Check these limits
- Do not use a universal stopping threshold.
- Do not equate repeated accounts with market validation.
- Request specialist review before treating saturation as a formal method.
