Input Requirements Context about your product, feature, or problem Relevant data, research, or constraints (recommended but optional) Clear articulation of what you're trying to achieve 7 Powers: The Foundations of Business Strategy What It Is 7 Powers is a framework for understanding sustainable competitive advantage. The core insight: Business value comes from possessing an attribute that produces higher returns than competitors AND a barrier that prevents competitors from arbitraging it away. Power = Benefit + Barrier Warren Buffett famously said: "In business, I look for economic castles protected by unbreachable moats." Power is understanding what makes something a castle (the benefit) versus a shack, and what makes the moat unbreachable (the barrier). The key shift: Move from asking "What's our competitive advantage?" to asking "What economic structure creates durable differential returns?" When to Use It Use 7 Powers when you need to: Evaluate a business's long-term defensibility (investment decisions, competitive analysis) Design a startup for durability (not just product-market fit) Understand why incumbents can't respond to your disruptive move Prioritize strategic initiatives based on what builds power Identify whether you actually have a moat or just operational excellence Plan second acts (new business lines that could develop power) Win market share battles in high-growth phases When Not to Use It You don't have product-market fit yet The business is purely commodity with no differentiation possible You want to justify a strategy you've already decided on You're optimizing operations (power is about structure, not execution) Resources Books: 7 Powers by Hamilton Helmer Good Strategy Bad Strategy by Richard Rumelt Competition Demystified by Bruce Greenwald Further Reading 7 Powers
