An indepth study of how to select and train for effective leadership is based on the belief that though innate character traits play a role of leadership, leadership potential can be developed. The author's theory known as "functional leadership," stresses that leadership is an interaction among leader, group members, and situation. The good leader is the one who, by virtue of his personality, knowledge and training, is able to provide the functions necessary to enable the group to achieve its task and to hold it together as a working team. The book also discusses the functional approach to leadership, field leadership training, developing leadership in industry, and leadership training for junior managers. The author draws on numerous examples--soldiers, explorers, politicians, businessmen--to illustrate the good leader. (PT)
