Nelson Mandela deals with his leadership concept ‘leading from behind’ in his autobiography ‘Long walk to freedom’. Linda A. Hall, a professor at Harvard Business School, cites Mandela as follows when she claims his leadership style will be crucial for companies in order to establish adequate leadership practices for the future:
A leader, he said, is like a shepherd. He stays behind the flock, letting the most nimble go out ahead, whereupon the others follow, not realizing that all along they are being directed from behind. (Quote from Linda A. Hall on MBA Depot blog.)
I guess the Japanese train staff above read Mr Mandela a bit too literally.
