Ethnographic studies of CSCW have often seemed to involve the investigation of relatively large-scale and highly specific systems, consequently ignoring the small office within which many people spend much of their working lives and which is a major site for the introduction and implementation of IT. This paper is concerned with a “quick and dirty” ethnographic study of a small office that was considering the introduction of greater levels of IT. Generic features of office work are outlined: the process of work in a small office and its recurrent features, notably the massive volume of paperwork; the importance of local knowledge in the accomplishment of work; and the phenomenon of “constant interruption.” This paper suggests that despite the obvious contrasts with work settings analysed in other ethnographic studies, similar features of cooperative work can be observed in the small office. It further suggests that the issues of cooperation and the sociality of work cannot be ignored even in small-scale system design.
