    The Importance of Context in Information System Design: An Assessment of Participatory Design (1999)
    Springer
    Requirements engineering 4 (1999), S. 103-114 
    Details
    ISSN: 1432-010X
    Keywords: Key words:Industrial democracy – Participatory design – Systems development – Work organisation

    Topics: Computer Science
    Notes: This paper is predicated on requirements analysis as the Achilles heel of information systems development, and accepts that information systems often disappoint. Most design paradigms can be located within a rationalistic framework polarised by requirements analysis and system delivery. Such traditional design paradigms are seen as palliatives that prevent us moving toward more satisfying information systems. It is argued that this rationalistic framework forces us to identify, and attempt to solve, problems that are symptomatic of the approach adopted. A pluralistic framework for information system development is presented which rejects the notions of requirements analysis and system optimality. Participatory design, derived from the field of human computer interaction, is located within this framework and identified as a possible paradigm for information system development. A case study is conducted to assess the benefits of participatory design techniques and to evaluate the extent to which participatory design can overcome the failings of traditional methodologies.

    An Evaluation of the Potential of Task Analysis in the Evolution of Interactive Work Systems (2000)
    Springer
    Cognition, technology & work 2 (2000), S. 7-15 
    Details
    ISSN: 1435-5566
    Keywords: Key words: Evolutionary development – Interactive work systems – Task analysis – Task knowledge structures

    Notes: Abstract: Developed forms of task analysis allow designers to focus on both utility and usability issues in the development of interactive work systems. The models they generate represent aspects of the human, computer and domain elements of an interactive work system. Many interactive work systems are embedded in an organisational context. Pressure for changes are present in this context and provide impetus to stakeholders to change work tasks and the supporting tools. Interactive work systems also provide evolutionary pressures of their own, changing the very task they were designed to support. One approach to coping with change has been to evolve interactive work systems. Currently none of these techniques place focus on the performance of tasks as central, and consideration of usability is minimal. However, an evolutionary design approach forces an evolutionary experience upon users, and we cannot be sure whether this approach enhances the user’s experience or degrades their performance. Given the strength of task analysis it is likely that it will be applied within evolutionary contexts. Yet, little work has been undertaken to examine whether its role will, or could be different. We ask how we can move task analysis towards being used in a principled manner in the evolution of interactive work systems. This paper examines a number of features of the approach called task knowledge structures that may be useful in evolving interactive work systems. We look at tasks and their representativeness, roles, goals, objects (their attributes, relationships, typicality and centrality) and actions. We present a developing framework for examining other task analysis approaches for their utility in supporting interactive work systems evolution. Finally, we discuss future work within the area of applying task analysis in the evolution of interactive work systems.

    User Environments and Individuals: Experience with Adaptive Interface Agents (2000)
    Springer
    Cognition, technology & work 2 (2000), S. 16-26 
    Details
    ISSN: 1435-5566
    Keywords: Key words: Adaptive interfaces – Interface agents – Interface architectures – Object orientation – Software agents
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine , Technology
    Notes: Abstract: The traditional style of working with computers generally revolves around the computer being used as a tool, with individual users directly initiating operations and waiting for the results of them. A more recent paradigm of human-computer interaction, based on the indirect management of computing resources, is agent-based interaction. The idea of delegation plays a key part in this approach to computer-based work, which allows individuals to relinquish the routine, mechanistic parts of their everyday tasks, having them performed automatically instead. Adaptive interfaces combine elements of both these approaches, where the goal is to have the interface adapt to its users rather than the reverse. This paper addresses some of the issues arising from a practical software development process which aimed to support individuals using this style of interaction. This paper documents the development of a set of classes which implement an architecture for adaptive interfaces. These classes are intended to be used as part of larger user interface systems which are to exhibit adaptive behaviour. One approach to the implementation of an adaptive interface is to use a set of software “agents”– simple processes which effectively run “in the background”– to decompose the task of implementing the interface. These agents form part of a larger adaptive interface architecture, which in turn forms a component of the adaptive system.

    The Display of Electronic Commerce within Virtual Environments (2000)

    ISSN: 1435-5566
    Keywords: Key words: E-commerce – Heuristic evaluation – Human factors – Virtual reality – Web display

    Notes: Abstract: In today’s competitive business environment, the majority of companies are expected to be represented on the Internet in the form of an electronic commerce site. In an effort to keep up with current business trends, certain aspects of interface design such as those related to navigation and perception may be overlooked. For instance, the manner in which a visitor to the site might perceive the information displayed or the ease with which they navigate through the site may not be taken into consideration. This paper reports on the evaluation of the electronic commerce sites of three different companies, focusing specifically on the human factors issues such as perception and navigation. Heuristic evaluation, the most popular method for investigating user interface design, is the technique employed to assess each of these sites. In light of the results from the analysis of the evaluation data, virtual environments are suggested as a way of improving the navigation and perception display constraints.
