Content Summary

In "Competition Demystified," Greenwald and Kahn challenge the conventional wisdom of strategic planning by simplifying the core concepts into more digestible elements. The book emphasizes the following key concepts:

  • Simplified Approach to Business Strategy: The authors advocate for a straightforward strategy framework that prioritizes understanding and leveraging barriers to entry over more complex models.
  • Role of Barriers to Entry: Central to the book's thesis is the idea that barriers to entry are the most critical factor in determining competitive advantage. Companies that can establish and maintain significant barriers can achieve and sustain superior profitability.
  • Importance of Competitive Advantages: The book explores how companies can identify and exploit their unique competitive advantages to achieve market dominance.

Core Topics Covered:

  1. Differentiation vs. Cost Leadership: Greenwald and Kahn discuss the two primary strategies companies use to compete—differentiation (offering unique products or services) and cost leadership (becoming the lowest-cost producer). They analyze when and how each strategy can be effectively employed.
  2. Strategic Positioning: The authors explain the importance of strategic positioning in creating a sustainable competitive advantage. This involves choosing a clear path based on either differentiation or cost leadership and aligning resources and capabilities accordingly.
  3. Case Studies on Real-World Companies: The book includes numerous case studies of well-known companies such as Walmart, Microsoft, and Coca-Cola, illustrating how these companies have used barriers to entry and competitive advantages to secure their market positions.
  4. Analysis of Competitive Forces: While the book diverges from Michael Porter's five forces model, it still addresses key competitive forces such as rivalry among existing competitors, the threat of new entrants, and the bargaining power of suppliers and customers. Greenwald and Kahn provide a simplified perspective on these forces, focusing on their practical implications.

By breaking down these complex topics into more manageable parts, "Competition Demystified" offers finance professionals and business strategists practical tools and insights for developing robust business strategies. The book’s emphasis on barriers to entry and competitive advantages serves as a foundation for understanding how companies can protect their market positions and achieve long-term success.

Critical Analysis


  1. Clear and Simplified Explanation of Complex Concepts:
    • One of the standout strengths of "Competition Demystified" is its ability to distill complex strategic theories into clear, straightforward explanations. Greenwald and Kahn break down intricate concepts into more accessible ideas, making the book suitable for a wide range of readers, from students to seasoned finance professionals.
  2. Practical Examples and Case Studies:
    • The book is rich with practical examples and case studies that illustrate the application of its strategic principles in real-world scenarios. Companies like Walmart, Microsoft, and Coca-Cola are analyzed in detail, demonstrating how they have utilized barriers to entry and competitive advantages to dominate their markets. These case studies provide tangible insights that readers can apply to their own strategic planning processes.
  3. Focus on Barriers to Entry and Competitive Advantages:
    • Greenwald and Kahn's emphasis on barriers to entry as a critical component of strategic success is a refreshing take on business strategy. By prioritizing the identification and maintenance of these barriers, the authors offer a clear and actionable framework for achieving and sustaining competitive advantages.


  1. Limited Discussion on Dynamic Market Changes:
    • While the book provides a solid foundation for understanding competitive strategy, it lacks a comprehensive discussion on the dynamic nature of modern markets. The rapid pace of technological advancement and globalization means that market conditions can change swiftly, and the book's focus on static barriers to entry may not fully address these evolving challenges.
  2. Possible Oversimplification of Multifaceted Business Scenarios:
    • In an effort to make strategic concepts more accessible, Greenwald and Kahn may have oversimplified some aspects of business strategy. The streamlined approach, while beneficial for clarity, might omit important nuances and considerations that are critical in more complex or rapidly changing industries.

Comparative Analysis:

  • Comparison with Michael Porter's "Competitive Strategy":
    • Michael Porter's "Competitive Strategy" is often considered the gold standard in the field of business strategy. Porter's five forces model offers a comprehensive framework for analyzing competitive forces and industry dynamics. In contrast, "Competition Demystified" provides a more focused and simplified approach, emphasizing barriers to entry and competitive advantages.
    • While Porter's work delves into a broad range of competitive factors, Greenwald and Kahn narrow their focus to provide deeper insights into specific elements of competitive strategy. This makes "Competition Demystified" a more approachable read, though it may lack the depth and breadth of analysis found in Porter's work.
  • Unique Contributions and Differences:
    • Greenwald and Kahn's unique contribution lies in their radical simplification of business strategy, which can be particularly valuable for readers seeking a clear and direct framework for strategic planning. Their focus on barriers to entry as the cornerstone of competitive advantage sets their work apart from more traditional strategic models.
    • However, for readers who require a more comprehensive and detailed analysis of competitive forces and market dynamics, Porter's "Competitive Strategy" might be more suitable. The two books complement each other well, offering different perspectives and levels of detail that can enrich a reader's understanding of business strategy.

Overall, "Competition Demystified" offers a valuable and practical perspective on business strategy, particularly for those looking to understand and leverage barriers to entry and competitive advantages. Its strengths in clarity and practical application make it a useful resource, while its weaknesses highlight areas where more detailed or dynamic analyses might be needed.
