The frame of information systems research and development that I hope to have outlined is built around a deepening awareness of the work required to achieve technology stabilization, and one's location within the extended network of working relations that makes technical systems possible. To develop that awareness, our research needs to work across the grain of received categories and distinctions to recover the specific social, material, political and economic realites that those categories both reveal and obscure. It also requires redrawing boundaries and lines of interaction in such a way that identities of technology designer and user, and the relations between them, are transformed. This implies, in turn, that our interventions in identities and relations of technology production are part of a larger enterprise of disrupting and remaking the social world.
