A product team launches a critical feature adoption survey without testing. After collecting data, they discover respondents misinterpreted a key question about usage frequency, making the data unusable for planning.

Benefits:
Single-focus questions produce cleaner data and more actionable insights.
Ask test respondents to think aloud while answering questions to reveal misinterpretations.
Deploy the survey to a small sample to analyze response patterns and identify problematic questions.
Examine missing data, unusual patterns, and open-text responses for signs of confusion.
Make substantive changes based on findings, then test again to confirm improvements.
