Distributed Cognition is growing in popularity as a way of reasoning about group working and the design of artefacts within work systems. DiCoT (Distributed Cognition for Teamwork) is a methodology and representational system we are developing to support distributed cognition analysis of small team working. It draws on ideas from Contextual Design, but(More)
Emergency medical dispatch (EMD) is typically a team activity, requiring fluid coordination and communication between team members. Such working situations have often been described in terms of distributed cognition (DC), a framework for understanding team working. DC takes account of factors such as shared representations and artefacts to support reasoning(More)
There is a wealth of user-centred evaluation methods (UEMs) to support the analyst in assessing interactive systems. Many of these support detailed aspects of use – for example: Is the feedback helpful? Are labels appropriate? Is the task structure optimal? Few UEMs encourage the analyst to step back and consider how well a system supports users' conceptual(More)
Grounded Theory (GT) is used within HCI research, but nuances and more modern interpretations of the method are rarely discussed. This paper has two intentions: to offer guidance on practical issues when applying GT, and to clarify the space of methodological possibilities. We describe an extended GT study on understanding why practitioners choose(More)
Resilience markers for safer systems and organisations. Abstract. If computer systems are to be designed to foster resilient performance it is important to be able to identify contributors to resilience. The emerging practice of Resilience Engineering has identified that people are still a primary source of resilience, and that the design of distributed(More)
In recent years, there has been great interest in scenario-based design and other forms of user-centred design. However, there are many design processes that, often for good reason, remain technology-centred. We present a case study of introducing scenarios into two digital library development processes. This was found to disrupt established patterns of(More)
In this paper we describe results from an exploratory study observing infusion pump use in practice. From 31 observations of pump programming we note 10 low-level disturbances, which we conceptualise in terms of unremarkable error. This data supports a view that well performing systems cope with error as part of their normal work. Users are able to recover(More)
This exploratory study aims to gain insight into how usability practitioners work in professional web design. This is done through interviews and a grounded analysis. The description reported here refers to the wider influence of the commercial context on usability work. This brings to the fore such issues as: the client's influence on work, negotiation(More)
