Competition Demystified
A Radically Simplified Approach to Business Strategy
by Bruce Greenwald and Judd Kahn
“Greenwald and Kahn provide a clear and practical guide for analyzing industries and identifying competitive advantages. I recommend this book to any manager or entrepreneur seeking to better understand their competitive environment.”
Is Your Strategy Too Complicated to Work?
Most business leaders have been taught to think about strategy through complex frameworks, analyzing a dizzying array of suppliers, buyers, substitutes, and rivals. This often leads to dense PowerPoint decks and strategic plans that are too convoluted to be truly effective. The result? Companies spend fortunes on initiatives that don't build any lasting advantage, leaving them vulnerable to the next market shift.
But what if real, durable strategy is radically simpler? What if it all boils down to one single question? In Competition Demystified, Columbia Business School professor Bruce Greenwald and his co-author Judd Kahn argue just that. They cut through the noise of traditional strategic planning to offer a refreshingly focused approach. Their core thesis is that true competitive advantage, the kind that leads to sustainable, high profits, exists only when there are significant barriers to entry. If competitors can easily enter your market and do what you do, you don't have a strategy; you have a temporary head start.
What You'll Learn
The One Question That Matters: Why "Are there barriers to entry?" is the most critical strategic question you can ask.
The Real Sources of Power: Discover the three genuine types of competitive advantages: Supply, Demand, and Economies of Scale.
Why "Differentiation" Can Be a Trap: Understand why simply having a unique product or brand often isn't enough to protect you from competition.
The Importance of Being Local: Learn why dominating a small, local market can be far more profitable than competing nationally or globally.
A Simplified Strategic Framework: Get a clear, actionable method for analyzing your industry, your position, and where to focus your efforts.
Forget the Five Forces—Focus on the Moat
For decades, Michael Porter’s Five Forces have been the gold standard for strategic analysis. While Greenwald and Kahn acknowledge the framework's usefulness, they argue it creates too much complexity. It's easy to get lost analyzing all five forces and lose sight of the one that truly matters: the threat of new entrants.
Their logic is ironclad. If new competitors can easily enter your industry, any excess profits you make will inevitably be competed away. It doesn't matter how weak your suppliers are or how few substitutes exist; a flood of new rivals will drive prices and profits down to mediocre levels. Therefore, a sustainable competitive advantage is synonymous with a barrier to entry—a "moat," as Warren Buffett would say, that protects your castle from invaders. If there is no moat, there is no long-term advantage.
Imagine two coffee shops on the same block. One might have slightly better coffee or a more charming ambiance. But can a new coffee shop open across the street? Absolutely. The barriers to entry are incredibly low. This is not a structurally profitable market. Now, think about your local utility company. Can a new electric company start running power lines to your house? No. The regulatory hurdles and massive infrastructure costs create an almost insurmountable barrier to entry. That is a real competitive advantage.
The Three True Competitive Advantages
According to Greenwald, if a barrier to entry exists, it must manifest as one of three things. If you can't identify at least one of these in your business, you should be very skeptical about your long-term prospects.
Supply Advantages: This is the ability to produce your product or service at a consistently lower cost than your competitors, thanks to proprietary technology or unique access to resources. This is the rarest advantage. A company might have a patent on a drug manufacturing process that no one else can replicate. However, Greenwald warns that these advantages are often fleeting. Patents expire, and proprietary processes can be reverse-engineered.
Demand Advantages: This is about customer captivity. It means that customers are, for some reason, locked into buying from you, even if a competitor offers a similar product. This loyalty isn't just about branding; it's driven by real costs and habits.
Habit: Think about buying Heinz Ketchup or Coca-Cola. For many, it's an automatic purchase, not a conscious choice. Breaking that habit is difficult for a new entrant.
Switching Costs: This is the pain and expense a customer incurs to change suppliers. For example, a business that runs all its operations on Oracle's database software faces enormous costs and risks in migrating to a different system. The hassle of switching keeps them a captive customer.
Economies of Scale: This is the most common and often most durable competitive advantage. It exists when a company with a larger market share can produce its goods or services at a lower per-unit cost than its smaller rivals. A key insight from Greenwald is that these economies of scale are almost always local.
Think of Walmart in its early days. By building a dense network of stores in a specific region, it could saturate the area with advertising and support all its stores from a single, highly efficient distribution center. A new competitor opening just one or two stores couldn't possibly match that cost structure. This local scale advantage is why a company can be dominant in one city but struggle to compete in another.
Key Concepts at a Glance
Barriers to Entry: The single most important factor in strategy. If they don't exist, no true competitive advantage exists.
Competitive Advantage Defined: The ability of an incumbent firm to do what potential rivals cannot. This manifests as Supply, Demand, or Economies of Scale advantages.
Supply Advantages: Having access to proprietary technology or processes that lead to a lower cost structure. Often temporary.
Demand Advantages: Customer captivity due to habit or high switching costs. More durable than supply advantages.
Economies of Scale: Lower per-unit costs that result from higher volume. These advantages are typically local, not global.
Local vs. Global Competition: Recognizing that most meaningful competition happens within a specific, narrowly defined geographic or product market.
Analyzing Your Competitive Landscape
Greenwald and Kahn’s framework provides a clear, step-by-step process for analyzing your own business.
Define the Market: Be precise. Are you competing globally, nationally, or just in one city? Is your market "all sedans" or "luxury electric sedans"? A clear definition is the essential first step.
Identify the Players: List all the competitors in that defined market. What are their market shares? If market shares are stable over time, it's a good sign that barriers to entry might exist. If they are constantly shifting, it's likely a competitive free-for-all.
Look for the Moat: Analyze the dominant players. Do they have any of the three true competitive advantages?
Economies of Scale: Does the market leader have a significant cost advantage due to their local market share?
Demand Advantages: Are customers locked in by habit or high switching costs?
Supply Advantages: Do they possess a unique technology or process that is protected and difficult to replicate?
Assess Your Position: If a moat exists, where are you relative to it? Are you the castle owner, or are you one of the firms struggling outside the walls? If no moat exists, you must accept that your business is in a brutally competitive arena where operational efficiency is the only way to survive.
Final Reflections
Competition Demystified provides a powerful and clarifying lens for viewing business strategy. By stripping away unnecessary complexity, Bruce Greenwald and Judd Kahn force leaders to confront the only thing that truly matters for long-term profitability: the presence of a durable competitive advantage. Their focus on barriers to entry—specifically supply, demand, and economies of scale—offers a disciplined and practical framework. It challenges us to look past appealing but flimsy concepts like "differentiation" and to honestly assess whether we operate from a position of true, defensible strength. This book is an essential read for any manager, entrepreneur, or investor who wants to move beyond buzzwords and build a truly resilient enterprise.
