"Herbert Casson was a highly prolific writer on management, with a career as a management guru spanning some four decades. A skilled writer who was also a successful entrepreneur, he used his own experiences and acute observations of the world around him to develop a philosophy of management based on the concept of ‘efficiency’. He published more than seventy books, which by the time of his death had sold more than half a million copies around the world. Something of a maverick, he was never really accepted by the business academic community in either Britain or America. His books were popular and populist, highly entertaining and full of penetrating insight."
