Michael Porter's Five Forces Framework

Overview

  • The Five Forces framework is used to analyze the external forces affecting a firm's profitability.
  • Industry: A group of firms producing close substitute products or services.
  • Industry structure affects firm profitability.
  • Key focus: Analyzing industry forces for profitability and competition insights.

Importance of Industry Analysis

  • Critical for understanding firm profitability.
  • Differentiates industries based on long-term average profitability.
  • Example industries:
    • Soft Drinks: High profitability (37.6% returns) due to strong brands and low competition.
    • Pharmaceuticals: High profits (31% returns) due to patents and limited competition.
    • Airlines: Low profitability due to high competition and low differentiation.

The Five Forces Explained

  1. Threat of Buyers

    • Buyers have power when few potential buyers exist.
    • Undifferentiated products and low switching costs increase buyer power.
    • Example: Walmart as a powerful buyer of generic denim.

  2. Threat of Suppliers

    • Suppliers pose a threat with few supply sources or unique products.
    • High switching costs benefit suppliers.
    • Example: Intel as a dominant supplier to IBM.

  3. Threat of New Entrants

    • Barriers to entry protect incumbents from new competitors.
    • High entry costs, regulations, economies of scale, and brand advantages are barriers.
    • Example: Procter & Gamble using brand strength and economies of scale.

  4. Threat of Substitutes

    • Substitute products fulfill needs differently and from outside the industry.
    • Example: Butter vs. margarine substitutes.

  5. Threat of Rivalry

    • High rivalry occurs with many competitors, slow growth, and low differentiation.
    • Example: Farming industry with many similar producers.

Application: Denim Jeans Industry

  • Supplier Power: Low threat due to many cotton suppliers.
  • Buyer Power: High threat from concentrated retail stores.
  • Barriers to Entry: Low, with common and cheap generic brands.
  • Substitute Products: High threat from various types of pants.
  • Rivalry: High, with many brands competing in different price points.

Conclusion

  • Denim manufacturing is not a highly profitable industry due to high threats from most forces except suppliers.
  • Takeaway: Industry analysis via the Five Forces helps evaluate market entry and competition.
