Reg Revans was the father of Action Learning, a process that help people to learn from each others, and solve problems. This originated from his experience while he was in his doctoral degree study in Cambridge. He was particularly interested in the idea of humility that if people will learn, they have to be humble. He brought together managers to help them learn from each other, and he devised a process to do that, which he called Action Learning. This process became very famous, and it spread throughout England and much of Europe. He became famous because of this.
