What is Porter's Five Forces?
Porter's Five Forces is a strategic management framework created by Michael Porter in 1979 to analyze the competitive intensity of an industry. It helps businesses understand where power lies in a market so they can shape strategy and protect profitability.
Porter's Five Forces identifies five forces — competitive rivalry, threat of new entrants, bargaining power of suppliers, bargaining power of buyers, and threat of substitutes — that together determine how attractive and profitable an industry is.
- 1↓Competitive RivalryIntensity of competition among existing firms in the industry.
- 2↓Threat of New EntrantsHow easily new competitors can enter the market.
- 3↓Bargaining Power of SuppliersHow much suppliers can raise prices or reduce quality.
- 4↓Bargaining Power of BuyersHow much customers can push prices down or demand more value.
- 5Threat of SubstitutesHow easily customers can switch to an alternative product or service.
Step-by-step worked examples
Analyze the threat of new entrants in the airline industry.
High capital costs (aircraft, gates, licenses) create a strong entry barrier Regulatory approval and safety certification add further barriers Conclusion: threat of new entrants is LOW, which supports higher industry profitability
Assess buyer power in the fast-food industry.
Many competing chains offer similar products (low switching cost) Customers are highly price-sensitive and can easily switch brands Conclusion: buyer power is HIGH, which pressures prices and margins
Evaluate the threat of substitutes for the coffee shop industry.
Alternatives include home-brewed coffee, tea, energy drinks, and other cafés Switching cost for the customer is very low Conclusion: threat of substitutes is HIGH, forcing coffee shops to differentiate on experience and quality
