Design guidelines for system administration tools developed through ethnographic field studies

Abstract

Information Technology system administrators (sysadmins) perform the crucial and never-ending work of maintaining the technical infrastructure on which our society depends. Computer systems grow more complex every year, however, and the cost of administration is an ever increasing fraction of total system cost - IT systems are growing harder to manage. To better understand this problem, we undertook a series of field studies of system administration work over the past four years, visiting a variety of enterprise and large university sites. One of our most compelling observations was how often the tools used by system administrators were not well aligned with their work practices. We believe that this misalignment was the result of administration tools designed without a complete understanding of the full context of administration work. To promote the design of better tools, this paper describes system administration work in more detail based on examples from our field studies, outlines the dimensions along which enterprise sysadmins differ significantly from other computer users, and provides a set of guidelines for tools to better support how administrators actually work.
