Groupware Technology and Software Reuse

Computer-Supported Cooperative Work (CSCW) is a research field concerned with the design and implementation of systems to support cooperative work. Such systems are usually called Groupware. Although Software Reusability (SR) is not commonly mentioned as an issue in the CSCW community, there are some obvious overlaps in design issues and methodologies.\ud In this paper I will argue that reusability issues are of particular importance to groupware technology and relate our experiences in this matte

Designing Tailorable Technologies

This paper provides principles for designing tailorable technologies. Tailorable technologies are technologies that are modified by end users in the context of their use and are around us as desktop operating systems, web portals, and mobile telephones. While tailorable technologies provide end users with limitless ways to modify the technology, as designers and researchers we have little understanding of how tailorable technologies are initially designed to support that end-user modification. In this paper, we argue that tailorable technologies are a unique technology type in the same light as group support systems and emergent knowledge support systems. This unique technology type is becoming common and we are forced to reevaluate existing design theory, methods of analysis, and streams of literature. In this paper we present design principles of Gordon Pask, Christopher Alexander, Greg Gargarian, and Kim Madsen to strengthen inquiry into tailorable technologies. We then apply the principles to designing tailorable technologies in order for their design to become more coherent and tractable. We conclude that designers need to build reflective and active design environments and gradients of interactive capabilities in order for technology to be readily modified in the context of its use

A Theory of Tailorable Technology Design

Tailorable technologies are a class of information systems designed with the intention that users modify and redesign the technology in the context of use. Tailorable technologies support user goals, intentions, metaphor, and use patterns in the selection and integration of technology functions in the creation of new and unique information systems. We propose a theory of tailorable technology design and identify principles necessary for the initial design. Following a Kantian style of inquiry, we identified four definitional characteristics of tailorable technology: a dual design perspective, user engagement, recognizable environments, and component architectures. From these characteristics, we propose nine design principles that will support the phenomenon of tailoring. Through a year-long case study, we refined and evidenced the principles, finding found that designers of tailorable technologies build environments in which users can both interact and engage with the technology, supporting the proposed design principles. The findings highlight a distinction between a reflective environment, where users recognize and imagine uses for the technology, and an active environment in which users tailor the technology in accordance with the imagined uses. This research contributes to the clarification of the role of theory in design science, expands the concept of possibilities for action to IS design, and proposes a design theory of a class of information systems for testing and refinement

Designing Tailorable Technologies

Tailorable technologies are technologies that are modified by users in the context of their use and are around us as desktop operating systems, web portals, and mobile telephones. While tailorable technologies provide users with limitless ways to modify the technology, as designers and researchers we have little understanding of how this should affect design. In this paper we present principles from four designers to strengthen inquiry into tailorable technologies. We then apply the principles to the case of the design of a web portal. We conclude that designers need to more consciously build reflective and active design environments and gradients of interactive capabilities in order for technology to be readily modified in the context of its use

User-Oriented Authorization in Collaborative Environments

Access rights for collaborative systems tend to be rather complex, leading to difficulties in the presentation and manipulation of access policies at the user interface level. We confront a theoretical access rights model with the results of a field study which investigates how users specify access policies. Our findings suggest that our theoretical model addresses most of the issues raised by the field study, when the required functionality can be presented in an appropriate user interface

Component-based Groupware Tailorability using Monitoring Facilities

Tailorability has long been recognised as a key issue concerning groupware applications in general and component-based groupware applications in particular. Tailoring activities are usually classified according to three levels, viz., customisation, integration and extension. This paper presents an approach to component-based tailoring based on the use of monitoring extensions. Our approach allows the extension and integration of new components into a legacy groupware application without the need for changes in the existing components
