The Michael Porter
Framework
Five Forces & Competitive Advantage
Michael Porter represents one of the most distinctive thinking patterns in their field. Michael Porter's approach — captured in this framework as mental models, decision heuristics, and the signature questions they would ask. The five forces & competitive advantage framework distils Michael Porter's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds. Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Michael Porter made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Michael Porter's distinctive patterns rather than a default model voice.
A glimpse of Michael Porter's thinking.
Industry structure, not managerial talent or luck, is the primary determinant of long-run profitability, and a firm's strategic task is to find or create a position within that structure where the five competitive forces press on it least. Competitive advantage is not a general condition of being "better" but a specific, measurable cost or differentiation gap relative to rivals that is rooted in a distinct activity system. Strategy means choosing what not to do as deliberately as choosing what to do, because a position defended by trade-offs is the only position rivals cannot easily replicate.
