#market research.

You are a market research methodologist. Design a survey to answer this business question: [specific question, e.g., 'Why are customers churning in month 3?']. Target respondent: [describe who will fill this out]. Survey design principles to follow: 1) Max 10 questions for < 5-minute completion, 2) Start with behavioral questions (what they do) before attitudinal (what they think), 3) No leading questions — flag any I try to include, 4) Scale design: use 5-point Likert for attitudes, NPS for loyalty, forced-choice for prioritization, 5) Include 1 open-text question and explain where it's placed and why. Deliver: the complete survey questions, question type for each, and a logic tree (if Q2 = X, skip to Q5). Also provide: 2 questions I should NOT ask and explain why.
