Business Strategy

Understanding Michael Porter: The Essential Guide to Competition and Strategy (Summary)

by Joan Magretta

In the mid-1990s, Continental Airlines launched 'Continental Lite' to copy the wildly successful low-fare model of Southwest Airlines. It was a catastrophic failure that cost them hundreds of millions. Why? Because they copied the visible parts—low fares and quick turnarounds—but failed to understand the hidden system of trade-offs. They tried to be a full-service airline and a low-cost one, creating a Frankenstein's monster that was good at nothing. This costly mistake reveals the most misunderstood lesson in business: strategy is not about what you do, but about what you choose not to do.

Competition Isn't About Being the Best, It's About Being Unique

The biggest mistake in strategy is competing to be the best. This inevitably leads to a zero-sum game of imitation and price wars. Real strategy is about carving out a distinctive position by serving different needs, different customers, or the same customers differently.

IKEA doesn't try to be the 'best' furniture store. They target young, price-sensitive buyers who are willing to trade service and convenience (like assembly and delivery) for modern design at a radically lower price. They deliberately chose not to compete with traditional furniture stores on service.

Your Industry's Structure Determines Its Profitability

Before you can create a strategy, you must understand the landscape. Porter's Five Forces (threat of new entrants, power of suppliers, power of buyers, threat of substitutes, and rivalry) analyze an industry's underlying structure and reveal why profitability is consistently high in some industries and low in others.

The airline industry is chronically unprofitable because all five forces work against it: low barriers to entry, powerful suppliers (Boeing, Airbus), powerful buyers (price-shopping customers), easy substitutes (cars, trains), and intense rivalry. In contrast, the market for carbonated soft drinks has long been a profit machine due to high barriers to entry (brand, distribution), relatively weak buyers, and limited substitutes.

Strategy is a System of Interlocking Activities

A successful strategy is not a single brilliant move or core competence. It's an entire system of interlocking activities that fit together and reinforce one another, creating a competitive advantage that is difficult for rivals to imitate.

Southwest Airlines' low-cost advantage isn't just cheap tickets. It's a whole system: flying only one type of plane (Boeing 737) simplifies maintenance; no assigned seating or meals speeds up gate turnaround times; point-to-point routes avoid costly hub delays. A competitor can't just copy one piece; they must copy the entire tightly integrated system.

A Company Must Choose Its Position: Low Cost or Differentiation

There are only two ways to gain a competitive advantage. You can perform similar activities as your rivals but at a lower cost, or you can perform different activities that deliver unique value for which customers will pay a premium. Trying to do both is a recipe for getting 'stuck in the middle.'

In the auto industry, Toyota historically won with operational excellence and cost leadership, producing reliable cars at a lower cost. In contrast, BMW wins through differentiation, offering superior engineering and a 'driving machine' brand experience that commands a premium price. A company trying to be a 'premium low-cost' carmaker would likely fail.
