Fourth in a series on public personnel administration, this book discusses problems in personnel and organizational development (OD) and the resources potentially available to solve them, then indicates some of the ways in which employee development might be facilitated. Basic steps in the systems approach to development are outlined, followed by supervisory and other roles and functions, the nature of the OD process, and the need for written training plans and policies. Adult learning principles and specific methods and kinds of resources are considered, together with requirements for application to various situations. Such factors as sponsorship and funding, choice of courses and facilities, use of audiovisual aids, identification of potential candidates for management development and trainee evaluation, are also examined. Numerous individual and group approaches to training are described--role playing, programed instruction, lectures, conferences, workshops, critical incidents, brainstorming, "in-basket" exercises, and others. Finally, attention is given to special training situations, especially those connected with manpower development, and to emerging or anticipated trends. (LY)
