In a world where technology makes everything easier and cheaper, competitive advantage increasingly comes from business model innovation rather than product superiority. Strategy textbooks taught us that sustainable competitive advantage that commanded premium prices was best protected by powerful barriers to entry. Build a moat, create switching costs, leverage access to high costs of entry, own distribution channels, and it would be difficult for startups to compete for your markets. But the forces of disruption operate by different rules, systematically destroying the very foundations of pricing power by making the previously difficult and expensive suddenly easy and cheap. The basis of competition changes, from excellence along well understood dimensions of merit to “good enough.”
