Institutional and technical aspects of manpower planning are discussed in the context of a systematic approach to organizational manpower planning in the public sector. Opening chapters present an overview of manpower planning and review the typology and history of the field. Subsequent chapters present institutional background material with which the micromanpower planner must become familiar in order to insure effective planning. Included are a discussion of the economics of the labor market; a review of the human resource development system of the United States; details on specific aspects of that system (manpower training, personnel administration, and human engineering); and a review of the expanding role of labor unions and collective bargaining in the public sector. Principles of general planning theory are then outlined, and the specifics of a system of micromanpower planning in the public sector are delineated. Individual chapters are devoted to description of the manpower dimensions of the organization, measurement of current employment characteristics, forecasting future employment characteristics, identification and analysis of manpower problems, development of manpower programs, performance control, and implementation of a manpower planning system. In addition to presenting new material, the volume consolidates two manuals used in U.S. Environmental Protection Agency, Office of Water Programs Operations manpower workshops. Schematic diagrams and lists of selected references accompany the text.
