This book is divided into four sections. Part I, "Preparing To Train," presents three reasons why supervisory training and development are worth the time and money they cost. These are: (1) Training can improve a supervisor's attitudes, knowledge, and skills, and increase his effectiveness and that of his department; (2) New knowledge--both technical and managerial--must be acquired in order to effectively perform first-level management jobs; (3) Training and development can prepare for effective performance of higher level positions. Part II, "Training Methods and Evaluation," describes some of the common techniques for training supervisors. The most important method is on-the-job development in which the boss is heavily involved. Part III, "Case Examples of Effective Programs," gives details of training programs in operation in certain large companies in the United States. Part IV, "Selecting and Training Potential Supervisors," discusses two ways in which a company can select a supervisor: (1) last minute selection and placement and (2) pre-job training. Ideally, candidates for supervisory jobs should be systematically selected in advance of the job openings. They should have the qualifications necessary to be effective supervisors, including the desire to be a part of management. (CK)
