Knowledge Reuse Through Categorical Breakdown Analysis: A Method for Collaborative Systems Evaluation

Designing Computer-Supported Cooperative Work (CSCW) systems that support the widely varying needs of targeted users is difficult. There is no silver bullet technology that enables users to effectively collaborate with one another in different contexts. We propose a method of collaborative systems evaluation that enables novice evaluators to make insightful observations about the systems they evaluate at a level comparable to experts in certain situations. These observations come in the form of a categorical breakdown analysis of a laboratory study. The quantity and type of breakdowns can then be connected to recommended CSCW tools and features developed and described in the related literature. We conducted a study to explore the results generated when the method was applied by both experts and novices in the field of CSCW. We observed that experts found the method to be usable, and that novices capitalized on the knowledge embodied in the breakdown categories to make categorizations similar to those of experts

Use of scenario evaluation in preparation for deployment of a collaborative system for knowledge transfer - the case of KiMERA

This paper presented an approach for the evaluation of a collaborative system, after the completion of system development and software testing but before its deployment. Scenario and collaborative episodes were designed and data collected from users role-playing. This was found to be a useful step in refining the user training, in setting the right level of user expectation when the system started to roll-out to real users and in providing feedback to the development team

Information systems: a cyborg discipline?

This paper argues for a model of information systems in terms of cyborgs – a boundary-crossing mixture of the technical and the social. The argument for this model is substantiated from the personal experience of the author, presented as examples of being a cyborg researcher within a disciplinary context. Lessons for information systems are drawn

Requirements engineering for business workflow systems: a scenario-based approach

Workflow implementations require a deep understanding of business and human cooperation. Several approaches have been proposed to address this need for understanding, but largely in a descriptive way. Attempts to use them in software development have had mixed results. The work reported here proposes that these approaches can be used in a generative way, as part of the requirement engineering process, by (a) extending requirements engineering modelling techniques with underlying cooperation properties, (b) integrating these techniques through the use of a derivation modelling approach, and (c) providing pragmatic heuristics and guidelines that support the real-world requirements engineering practitioner to ensure a high probability of success for the business workflow system to be developed. This thesis develops and evaluates a derivation modelling approach that is based on scenario modelling. It supports clear and structured views of cooperation properties, and allows the derivation of articulation protocols from business workflow models in a scenario-driven manner. This enables requirements engineering to define how the expectations of the cooperative situation are to be fulfilled by the system to be built - a statement of requirements for business workflow systems that reflects the richness of these systems, but also acts as a feasible starting point for development. The work is evaluated through a real-world case study of business workflow management. The main contribution of this work is a demonstration that the above problems in modelling requirements for business workflow systems can be addressed by scenario-based derivation modelling approach. The method transforms models through a series of properties involving cooperation, which can be addressed by using what are effectively extensions of current requirements engineering methods

A conceptual toolbox for designing CSCW applications

This paper presents a conceptual toolbox, developed to support the design of CSCW applications in a large Esprit project, EuroCODE. Here, several groups of designers work to investigate computer support for cooperative work in large use organizations, at the same time as they work to develop an open development platform for CSCW applications. The conceptual toolbox has been developed to support communication in and among these design groups, between designers and users and in future use of the open development platform.Rejecting the idea that one may design from a framework describing CSCW, the toolbox aims to support design by doing and help bridging between work with users, technical design, and insights gained from theoretical and empirical CSCW research

Collaborative design : managing task interdependencies and multiple perspectives

This paper focuses on two characteristics of collaborative design with respect to cooperative work: the importance of work interdependencies linked to the nature of design problems; and the fundamental function of design cooperative work arrangement which is the confrontation and combination of perspectives. These two intrinsic characteristics of the design work stress specific cooperative processes: coordination processes in order to manage task interdependencies, establishment of common ground and negotiation mechanisms in order to manage the integration of multiple perspectives in design

Collaboration, Coordination and Computer Support: An Activity Theoretical Approach to the Design of Computer Supported Cooperative Work. Ph.D. Thesis

This thesis is written in partial satisfaction of the requirements for a Ph.D. in Computer Science performed within the Industrial Research Education Programme established between the University of Aarhus, Kommunedata and Aarhus University Hospital. The initial focus of the project was to investigate ways of supporting the extensive cooperation taking place within a hospital. The theoretical objective of this work is to apply activity theory as a theoretical foundation for CSCW research and to focus on the issue of design within CSCW
