Porter’s Five Forces
Evaluating Industry Attractiveness
7/2/20251 min read


Porter’s Five Forces is a powerful tool for analyzing an industry’s structure and potential profitability. It assesses competitive intensity and hence attractiveness of a market.
Threat of New Entrants: How easy is it for new players to enter the industry? Consider barriers like economies of scale, regulation, and capital requirements.
Bargaining Power of Suppliers: Do suppliers have leverage to dictate terms? Fewer suppliers or high switching costs increase this force.
Bargaining Power of Buyers: If customers have many options and low switching costs, their power increases.
Threat of Substitutes: Availability of alternatives can reduce industry profitability.
Industry Rivalry: The number and strength of competitors, along with product differentiation, impact this force.
This model is widely used for market research, competitive strategy, and M&A decisions.
