Tailorability is generally regarded as a key property of groupware systems due to the dynamics and differentiation of cooperative work. This article investigates the use of software components as a generic architectural concept for designing tailorable groupware applications. First, the issues raised by this approach are discussed in the context of an(More)
Design and evaluation of groupware systems raise questions which do not have to be addressed in the context of single user systems. The designer has to take into account not only the interaction of a single user with the computer, but also the computer-supported interaction of several users with each other. In this article we describe the use of cooperation(More)
The design of tailorable systems is an important issue for fields of application which are characterized by differentiation and dynamics. We show how tailorability can be combined with approaches of evolutionary and participative software-engineering and discuss some conceptual problems arising from this approach. Moreover, we present two case studies on(More)
Flexibility is one of the most striking features of modern software. As the idea of integrating components is easily understood by programmers as well as end users, component architectures seem to be very promising to serve as a technological basis. In this paper we give an overview of our work in the last years. A component model called FLEXIBEANS has been(More)

Tailorability is generally regarded as a key requirement for groupware applications. In this paper, we will focus on a specific class of tailoring activities: the definition of different system behaviour for specific scopes of validity. Since the state of the art in the CSCW literature does not yet offer any satisfactory solutions to support users in(More)
The goal of the ORGTECH-project is to improve the cooperation between two engineering offices on the one hand, and a major German steel mill, on the other. An integrated change process has been initiated which combines the introduction of a groupware application with methods of organization development. This change process draws on the framework of(More)
