Request DemoPorter's Five Forces is a framework for analyzing the competitive intensity and attractiveness of an industry. Developed by Harvard Business School professor Michael Porter in 1979, it examines five forces that shape every industry and market, helping organizations understand the structural factors that influence profitability.
The framework goes beyond simply looking at direct competitors. It recognizes that competitive pressure comes from multiple directions—customers demanding lower prices, suppliers seeking higher margins, new companies entering the market, and alternative solutions that might replace your product entirely.
Understanding these forces helps businesses identify where power lies in their industry, assess whether a market is worth entering, and develop strategies that position them favorably against competitive pressures.
The intensity of competition among existing firms in the industry. High rivalry typically leads to price competition, advertising battles, and frequent product improvements—all of which can erode profitability.
Rivalry intensifies when:
How easily new competitors can enter the industry. When barriers to entry are low, new players can quickly enter and compete away profits. High barriers protect existing companies.
Entry barriers include:
The availability of alternative products or services that serve the same purpose. Substitutes limit pricing power—if you charge too much, customers switch to alternatives.
Substitute threat increases when:
The ability of customers to pressure companies on price, quality, or service. Powerful buyers can demand lower prices or better terms, squeezing seller margins.
Buyer power increases when:
The ability of suppliers to influence terms—raising prices, reducing quality, or limiting availability. Powerful suppliers capture more of the value created in an industry.
Supplier power increases when:
Airlines face intense pressure from all five forces, explaining why the industry has historically struggled with profitability:
Enterprise software companies often enjoy better structural positions:
Be precise about which industry you're analyzing. "Technology" is too broad; "enterprise CRM software" is analyzable. The industry definition determines which competitors, substitutes, and suppliers are relevant.
For each force, list the relevant actors. Who are your competitors? Who could enter? What substitutes exist? Who are your buyers and suppliers? Being thorough here prevents blind spots.
Rate each force as high, medium, or low based on the structural factors. Support assessments with evidence—market data, observed behaviors, industry research. Avoid assumptions that aren't grounded in facts.
Consider how the forces interact. Which forces most threaten profitability? Where do opportunities exist? How might forces change over time with technology shifts or regulatory changes?
Use insights to shape strategy. Can you position your company where forces are weakest? Can you reshape forces in your favor—building switching costs, differentiating products, or consolidating buyer relationships?
Five Forces analysis leads to different strategic responses depending on what the analysis reveals:
Differentiate products to avoid direct price competition. Focus on segments where you have advantages. Build customer loyalty that makes switching unattractive.
Strengthen barriers through economies of scale, brand building, patents, or exclusive relationships. Respond aggressively to entry attempts to discourage future entrants.
Improve price-performance ratio continuously. Build switching costs into your product. Consider acquiring or partnering with potential substitute providers.
Diversify customer base to reduce dependence on any single buyer. Differentiate products to reduce price sensitivity. Create switching costs through integration or customization.
Develop alternative suppliers. Standardize inputs to enable switching. Consider backward integration. Build collaborative relationships with key suppliers.
Static snapshot. The framework captures industry structure at a point in time but doesn't inherently account for how rapidly industries can change. In fast-moving markets, today's analysis may be outdated quickly.
Industry boundaries blur. Digital disruption often comes from outside traditional industry definitions. Uber disrupted taxis, but it came from technology, not transportation. Five Forces struggles with cross-industry disruption.
Assumes competition is zero-sum. The framework emphasizes competitive pressure, but some industries thrive through collaboration, ecosystems, and complementary relationships not captured by the model.
Doesn't address internal capabilities. Five Forces analyzes industry structure, not your ability to compete within it. A favorable industry still requires strong execution to capture value.
Five Forces works best when combined with other analytical tools:
Porter's Five Forces connects to several strategic concepts. Barriers to entry is one of the five forces examined in depth. Competitive advantage addresses how to position favorably given industry forces. SWOT analysis complements Five Forces by adding internal assessment. Competitive intelligence provides the data needed to accurately assess each force. Strategic differentiation is often a response to intense rivalry revealed by Five Forces analysis.
