Sharp, Helen and Robinson, Hugh (2008): Collaboration and co-ordination in mature eXtreme programming teams. In International Journal of Human-Computer Studies, 20 (7) pp. 506-518

“Mature eXtreme programming (XP) teams are highly collaborative and self-organising. In previous studies, we have observed that these teams rely on two apparently simple mechanisms of co-ordination and collaboration: story cards and the Wall. Story cards capture and embody the user stories which form the basis of implementation, while the Wall is a physical space used to organise and display the cards being implemented during the current development cycle (called an iteration). In this paper, we analyse the structure and use of story cards and the Wall in three mature XP teams, using a distributed cognition approach. The teams work in different commercial organisations developing different systems, yet we find significant similarities between their use of these two artefacts. Although simple, teams use the cards and the Wall in sophisticated ways to represent and communicate information that is vital to support their activities. We discuss the significance of the physical medium for the story cards and the Wall in an XP team and discuss the considerations that need to be taken into account for the design of technology to support the teams.”

Nocera, Jose Abdelnour, Dunckley, Lynne and Sharp, Helen (2007): An Approach to the Evaluation of Usefulness as a Social Construct Using Technological Frames. In International Journal of Human-Computer Interaction, 22 (1) pp. 153-172

“This article describes an investigation of the way usefulness of an information system is shaped by sociocultural factors in a work context. It presents technological frames as a conceptual tool that helps to understand usefulness from this point of view. It suggests that developers and users shape their experience of the usefulness of a system through these technological frames. This is illustrated with a qualitative study, in which developers' expectations of the usefulness of an enterprise resource planning system differed from those of users, who experienced the usefulness of the same system in diverse ways. Technological frames are proposed as an analysis framework for assessing how context and local culture shape the utility and usability of systems in situ, that is, once they are deployed to their actual contexts of use.”

Sharp, Helen, Woodman, Mark and Hovenden, Fiona (2004): Tensions around the adoption and evolution of software quality management systems: a discourse analytic approach. In International Journal of Human-Computer Studies, 61 (2) pp. 219-236

“This paper reports some results from a project to uncover the non-technical factors that affect the adoption and evolution of software quality management systems (SQMS). The data which the paper discusses comes from interviews with people involved in the quality effort in four different companies. Our approach to data collection was to use semi-structured interviews and to encourage interviewees to talk about their experiences of quality management and software development in their own organizations. We analysed this data using discourse analysis, informed by ethnographic observation, and identified a number of themes, one of which was the tensions that exist around the adoption and evolution of SQMS. In this paper, we present and discuss our approach to discourse analysis and some results that illustrate the tensions we found. We hope, thereby, to demonstrate how software engineers may use a technique from the social sciences to better understand their own practices.”

Sharp, Helen (1991): The Role of Domain Knowledge in Software Design. In Behaviour and Information Technology, 10 (5) pp. 383-401

“If effective knowledge-based support is to be provided for software designers, the process of software design, and the classes of knowledge used by designers must be understood more clearly. It has been shown that software designer's experience of designing software in the current application domain has a significant effect on the production of a quality design. However, in gaining experience of designing software, a designer gains knowledge in various distinct areas, including software design and the application domain. It is currently unclear which elements of this experience are important. In particular, the role of application domain knowledge that is independent of software design is of great significance for builders of intelligent software design support systems, since the overheads involved in providing application domain knowledge for a variety of application domains in such systems would be huge. This paper reports on a study that has been carried out to gain insights into this question, based around the structured techniques of DeMarco (1979) and Yourdon and Constantine (1979). From this preliminary investigation it would appear that a designer's general knowledge of the application domain does not affect the quality of a design produced for a system in this domain; this runs contrary to current popular beliefs.”
