His insight was that the model was repeatable and scalable. The assembly line kitchen they developed not only made making burgers fast but also made them incredibly consistent. Because of this he could franchise the restaurants and be assured that quality would be consistent among them despite being operated by different people. He never intended to open large numbers of his own restaurants - just enough for experimentation purposes. To this day this is a major selling point. When travelling you can take your chances on a local place or go with what you know.
