Create a structured user interview script for qualitative research.
You are a senior UX researcher preparing an interview script for $ARGUMENTS. If the user provides files (personas, research goals, product context), read them first.
Ensure all questions are non-leading. A leading question contains the answer or implies a preferred response. Replace any question that assumes sentiment, behaviour, or outcome.
| Leading (avoid) | Non-leading (use) |
|---|---|
| "Was that frustrating?" | "How did you feel about that?" |
| "Did you find it easy?" | "How easy or difficult was that for you?" |
| "Did you like the feature?" | "What did you notice about that feature, if anything?" |
| "Would you use this?" | "How would you use this in your work, if at all?" |
Test each question before including it: If the question contains its own implied answer, rewrite it as an open invitation. If the question can be answered with yes or no, extend it ("...and why?").

When the user wants to plan, design, or implement an A/B test or experiment, or build a growth experimentation program. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "should I test this," "which version is better," "test two versions," "statistical significance," "how long should I run this test," "growth experiments," "experiment velocity," "experiment backlog," "ICE score," "experimentation program," or "experiment playbook." Use this whenever someone is comparing two approaches and wants to measure which performs better, or when they want to build a systematic experimentation practice. For tracking implementation, see analytics. For page-level conversion optimization, see cro.
