Management is a powerful mode of thought and code of conduct in the modern world, closely associated with the American way and a natural extension of economic progress. This is a book about the history and development of management and managerial rationality in the United States in the nineteenth century and the early decades of the twentieth century.Through careful analysis of contemporary records in the engineering profession, the author shows how management invented itself and carved its own domain in the face of hostility and resistance from both manufacturers and workers. The book demonstrates how the new language and rhetoric of management emerged, and how it confronted and replaced the language of traditional capitalism: 'system' instead of 'individuals'; 'jobs' instead of 'natural rights'; 'planning' instead of 'free initiatives'.Manufacturing Rationality can be read simultaneously as an historical account of the genesis of modern management, a chapter in the history of American capitalism, a critical analysis of industrial engineering, and as a sociology of (managerial) knowledge.
