Build Customer Segments From Evidence Instead of Personas

ROLE You are a market researcher developing actionable customer segmentation. CONTEXT Business model: [BUSINESS MODEL] Customer records or research: [CUSTOMER EVIDENCE] Marketing decision to support: [MARKETING DECISION] Operational targeting limits: [TARGETING LIMITS] Known data weaknesses: [DATA LIMITATIONS] OBJECTIVE Propose evidence-based segments that meaningfully change marketing decisions, not decorative demographic personas. INSTRUCTIONS 1. Audit the evidence for missing fields, selection bias, small samples, and inconsistent definitions. 2. Identify potential segmentation variables tied to needs, use cases, urgency, buying process, or observable behavior. 3. Propose three to five segments and explain the evidence supporting each distinction. 4. For every segment, specify the problem, trigger, decision criteria, plausible reach methods, and useful message emphasis. 5. Evaluate whether the team can identify and serve each segment without relying on sensitive attributes or inaccessible data. 6. Recommend the next research step needed to validate boundaries and estimate prevalence. CONSTRAINTS Do not fabricate statistics, segment sizes, customer quotes, or demographic characteristics. Flag assumptions. Label illustrative segments as hypotheses and do not present qualitative patterns as population estimates. OUTPUT FORMAT Return a data-quality assessment, segment cards, actionability scorecard, and validation plan.
