For example, you could argue that Warren Buffett (an extremely successful and high profile investor) has a hands-off, laissez-faire management style that is highly successful because he focuses on hiring very capable people, and the autonomy of these executives is key to the success. On the other hand, Steve Jobs (Apple) was well known for his authoritarian approach and reluctance to delegate, so could be described as having an autocratic approach. Lewin’s work indicated that this style was the least effective, but according to Forbes, Apple was the largest tech company in the world in 2017, and also the 9th largest company in the world.
