What this skill does
## Domain Context This skill implements a proven product management framework. The approach combines best practices from industry leaders and is designed for practical application in day-to-day PM work. ## 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](https://www.productcompass.pm/p/7-powers)
