This article discusses the relationship between sociological theory and method, ethnomethodology and design. The aim of Wes Sharrock and Dave Randall, the authors of this article, is to deal with the relevance, or otherwise, of ethnomethodology to information system (IS) design. The authors' reflections were prompted by discussions at a symposium on "interpretive methods" for IS design held at Brunei University, and at which it became apparent that there was some confusion about ethnomethodology as it relates to design. The current interest in ethnomethodology in IS communities, somewhat confusingly for the design's practitioners, comes about because there has been a recent, though arguably belated, interest in the so-called "qualitative" methods in IS work, thus aping a move previously made in other design communities such as Computer Supported Cooperative Work. Nevertheless, and it is too often forgotten, so-called methods like ethnography are in important respects not methods at all. The authors mean this in the sense that they provide no instructions for "how to do it." Most significantly, the injunction to "go out and look" tells people nothing about what to look at, and in what kind of detail. Moreover, the "method" gives no purchase on the significance or otherwise of the chosen subject in respect of design issues. Regardless of this, it seems that a naturalistic study of people's activities may offer a way into some kinds of IS problem.
