When is a mature, slow-growth business not a mature business? How do rapidly growing companies emerge from stagnant, dead-in-the-water industries? The station-wagon segment of the North American auto market was dying when, in 1984, Chrysler Corporation introduced the minivan. Over the next ten years, minivan sales grew eight times faster than did the industry overall. For the last 15 years, the do-it-yourself home-improvement business as a whole has grown barely 5% per year while Home Depot has racked up 20% growth. Overcapacity and flat demand plague the airline industry, but that hasn’t kept Southwest Airlines Company from growing seven times faster than the industry average over the past decade.
