This paper characterises the use of activity trackers as "lived informatics". This characterisation is contrasted with other discussions of personal informatics and the quantified self. The paper reports an interview study with activity tracker users. The study found: people do not logically organise, but interweave various activity trackers, sometimes with(More)
Testing is a key part of any systems engineering project. There is an extensive literature on testing, but very little that focuses on how testing is carried out in real-world circumstances. This is partly because current practices are often seen as unsophisticated and ineffective. We believe that by investigating and characterising the real-world work of(More)
In this paper we report on an ethnographic study of a small software house to discuss the practical work of software testing. Through use of two rich descriptions, we discuss that "rigour' in systems integration testing necessarily has to be organisationally defined. Getting requirements "right', defining "good' test scenarios and ensuring "proper' test(More)
Suchman&#8217;s book <i>Plans and Situated Actions</i> has been influential in HCI (Human Computer Interaction). The book is often discussed with reference to ethnographic fieldwork, sometimes being cited as if it were a field study. However, the book uses examples from a laboratory study and contains criticisms of ethnography. This article explores how and(More)
In this paper we report findings from a study of social network site use in a UK Government department. We have investigated this from a managerial, organisational perspective. We found at the study site that there are already several social network technologies in use, and that these: misalign with and problematize organisational boundaries; blur(More)
This paper examines how software developers discuss users and how such discussions are intrinsic to the negotiation and settling of technical decisions in the development and testing of a software product. Using ethnographic data, we show how the user features in conversations, not as a 'topic' but as 'context' to technical work. By understanding the user(More)
Many decision support tools have been developed over the last 20 years and, in general, they support what Simon termed substantive rationality. However, such tools are rarely suited to helping people tackle wicked problems, for which a form of procedural rationality is better suited. Procedurally rational approaches have appeared in both management science(More)
<b>Motivation</b> -- Bainbridge highlighted some of the ironies of automation 30 years ago and identified possible solutions. Society is now highly dependent on complex technological systems, so we assess our performance in addressing the ironies in these systems. <b>Research approach</b> -- A critical reflection on the original ironies of automation,(More)
