This study addresses issues of information technology (IT) use in the management of knowledge production process of high- precision organizations (HPO) whose requirements for high fidelity characterize a unique context of technical and organizational changes. The operation of HPOs requires constant decision-making with intense activities of information generation, sharing and interpretation as a form of organizational learning (Huber, 1991). The study will investigate engineers’ work practice in one group of HPOs, DRAM (Dynamic Random Access Memory) manufacturers in the semiconductor industry where physical fidelity drives a high level of confluence of technical and organizational requirements. As in Woolgar’s ethnographic study of IT development in organizations (1994), this study will lead us to examine the nature of HPOs’ design requirements for information system (IS).
