A feature of industry in recent years has been the growing emphasis placed on management as such leading to a closer examination of management and more self-examination by managers about their own duties and performance. Recent advances in technology, while putting a premium on scientific knowledge, have at the same time enhanced the importance of managerial skills. In the electrical industry-particularly in the supply and heavy manufacturing industries-an engineering training has always been an accepted path to the ranks of management. However, management calls for qualities and knowledge which are not necessarily related to technical competence. They can be developed by practice and training. But if advantage is to be taken of these it is important that the engineer should be keenly aware of the content of a manager's work, and that he should appreciate that it presents a challenge different from that of scientific knowledge and no less worthy of his attention.
