Spotlighting key aspects of the achievements of icons from all kinds of social domains clearly shows just how widely and effectively management knowhow can be used to attain specific objectives. The examples presented in this book underpin this assertion by demonstrating that management know-how is not only rife – or indeed useful or essential – in a business context. Many icons active in very different walks of life have utilized such knowledge, in some cases instinctively, unaware that in doing so, they were actually applying management know-how. Accordingly, icons can teach us a great deal about how we, too, can effectively apply management know-how, even though they would never describe themselves as managers.
