What have been the greatest changes in entrepreneurship in the last 25 years?
Jim Collins: About every 20 years, roughly, there is a fundamental idea that profoundly changes the economic landscape. The last really huge idea was around 1980, that entrepreneurship is a systematic, repeatable discipline. That is the most important management or economic idea of the past 40 years-entrepreneurship is not a mystery; it’s not alchemy. That idea is why you had the rise of venture capital, entrepreneur[ial] courses in business schools, and magazines like Entrepreneur.
