This study investigates the interaction between civil servants and politicians in a planning committee in a Swedish county council. As the committees are venues for preparation of future decision-making, civil servants and others are invited to inform and report to the politicians on different topics. The aim is to explore this local interaction process based on an analysis of requests and responses. It is shown that the communication between civil servants and politicians is pervaded by sociability in the form of (...) conversational routines. The article aims to recognize this sociability as an intrinsic part of knowledge coproduction processes. Civil servants and politicians negotiate different types of professional and common knowledge through routines that dislocate time, responsibility, roles, and protocol order. These lubricants – important but often circumvented in studies of policy-making – are explored as instances of conversational coproduction. (shrink)
