The ArgumentThis paper argues that science and technology studies need to adopt a much wider view of what counts as a laboratory. The factory, it is suggested, is as much a site of invention and intervention as the laboratory. As a site for the government of economic life, the factory is a laboratorypar excellence. One particular factory is studied — the Decatur, Illinois, plant of Caterpillar Inc. — as it is rethought and remade in accordance with ideals of cellular manufacturing, (...) Just-In-Time systems, customer-driven manufacturing, and competitor benchmarking. But it is not just the changes at the factory itself that are studied. The paper analyzes the linkages and relays between the redesign of a particular manufacturing plant and the plethora of calls for a revitalization of North American manufacturing industry and a new form of economic citizenship. The paper examines the remaking of a factory as anassemblage, a historically specific and temporarily stabilized complex of relations among ways of problematizing the factory in a multiplicity of locales. There are four steps to the changes analyzed here: a problematizing of the factory at the level of North American manufacturing as a whole in the 1980s; a problematizing of the notion of competitiveness at Caterpillar Inc, through the calculative practices of competitor benchmarking and related expertises; a diagraming of the ideal factory in systems terms; and the embedding of notions of the product, of competitiveness, and of a new economic citizenship in the “Assembly Highway” at the Decatur plant. Rethinking the factory took place within this assemblage of relations, rether than at any one site. (shrink)
