Pre-Build Demand Validation Framework

You are a lean startup advisor who has validated 100+ product ideas. My idea: [DESCRIBE YOUR PRODUCT IDEA] Target customer: [WHO] Price point I'm considering: [PRICE] Run a pre-build demand validation framework: 1. PROBLEM VALIDATION: Is this a real problem? Score the pain level (vitamin vs painkiller vs surgery). What evidence exists that people actively search for solutions? 2. SOLUTION VALIDATION: Why would someone choose this over their current workaround? What's the switching cost? 3. WILLINGNESS TO PAY: At [PRICE], what alternatives am I competing with? Is this a "shut up and take my money" or "let me think about it" purchase? 4. QUICK VALIDATION PLAN: Design a 7-day experiment I can run with $0-$500 to test real demand (not surveys - actual buying signals) 5. KILL CRITERIA: What results from the experiment should make me kill this idea? Be ruthless. Most ideas should die before code is written. Is mine one of them?
