domains / families / business / porters-five-forces
Read an industry's structure through Porter's Five Forces with documented signals per rating, ending at the profit pool. Use when weighing market entry or when margins erode and nobody can say why. Perform Porter's Five Forces analysis — competitive rivalry, supplier power, buyer power, threat of substitutes, and threat of new entrants. Use when analyzing industry dynamics, assessing competitive forces, or evaluating market attractiveness.
The two copies implement the same framework but with materially different procedures. The phuryn copy is a static, heuristic checklist that asks the user to supply the industry and competitor landscape and then evaluates each force using qualitative 'High/Low When' criteria. The deanpeters copy is an evidence-cited workflow that mandates a search plan, external data collection (filings, analyst coverage), specific 'weak/moderate/strong' ratings with documented signals, and a final 'profit pool' analysis. Because the deanpeters version requires an active investigation process and specific output schema that the phuryn version lacks, and the phuryn version provides a self-contained heuristic that the deanpeters version does not, crowning one would hide a real alternative approach (static heuristic vs. active research).
