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.
