Seven Powers

pmprompt/claude-plugin-product-management

Hamilton Helmer's 7 Powers framework helps you figure out if you actually have a defensible moat or just good execution. You feed it context about your product or business, and it walks you through identifying which of seven economic structures (like network effects, switching costs, scale economies) might create durable competitive advantage. The core insight is that power requires both a benefit and a barrier to prevent competitors from copying you. Use this when evaluating long-term defensibility, designing a startup for durability, or deciding which strategic initiatives actually build a moat. Skip it if you're still hunting for product-market fit or just optimizing operations.

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?"
