# Lean Startup Methodology A systematic approach to building startups and launching new products that shortens development cycles and rapidly discovers if a business model is viable. ## Core Principle **Entrepreneurship is a form of management.** Success doesn't require a perfect plan or brilliant insight—it requires a systematic process for testing assumptions, learning from customers, and iterating rapidly. **The foundation:** Most startups fail not because they couldn't build what they planned, but because they built the wrong thing. The Lean Startup methodology applies scientific experimentation to eliminate waste and accelerate validated learning. ## Scoring **Goal: 10/10.** When reviewing or creating product development plans, experiments, or metrics, rate them 0-10 based on adherence to Lean Startup principles. A 10/10 means full application of Build-Measure-Learn, validated learning, and evidence-based decisions; lower scores indicate waterfall thinking or waste. Always provide the current score and specific improvements needed to reach 10/10. ## The Build-Measure-Learn Loop The fundamental cycle of Lean Startup: ``` IDEAS ↓ BUILD → Product ↓ MEASURE → Data ↓ LEARN → Knowledge ↓ (back to IDEAS) ``` **Critical insight:** The loop is actually backward. Start with what you want to learn, determine metrics that will inform that learning, then build the minimum product to collect those metrics. **Reverse planning:...
