Systems analysis, which is also called cost/benefit analysis, the planning-programming-budgeting system, risk analysis, and technology assessment, has become the major planning and policy tool of government at all levels. Indeed, it is still gathering momentum in addressing the uncertainties associated with everything from the safety of nuclear energy to the effects of microelectronics. Examining this phenomenon critically, Ida R. Hoos reviews systems analytic techniques in their own circumscribed, simulated world and in the real one, drawing on a wide range of studies in health, education, welfare, crime, and many other areas of public concern, and giving special attention to information systems and databanks. In a new introduction and a new final chapter, Hoos expands her 1972 discussion to consider the ways in which systems analysis, now dominant, governs our present and determines our future. This title is part of UC Press's Voices Revived program, which commemorates University of California Press?s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact.
