Collaborative Working Environments : Group Needs Approach to Designing Systems for Supporting Spatially Distributed Groups

Collaboration in spatially distributed groups requires technological support for mediating collaborative activities and members’ interactions over time and distance. Technology provides multiple tools for supporting individual, social and task requirements of collaborative groups. Nevertheless, many aspects of computer-mediated interactions are not sufficiently explained and creating an effective computer-supported environment for collaborative groups as a combination of these tools remains a challenge. Meeting this challenge requires taking into consideration different aspects of collaborative interactions from both social and technological perspectives. This thesis discusses the social and technical aspects of collaboration in spatially distributed groups and introduces a design approach for collaborative working environments. Firstly, it presents a comprehensive overview of research on collaborative groups, summarizing three interrelated elements under the umbrella of the group needs approach: individual, task and group maintenance needs. Secondly, it proposes a design approach for collaborative working environments on the basis of group needs and thus presents an alternative for designing computer-supported environment for collaborative groups. This research considers two main types of systems for supporting collaborative groups – groupware and social software – and discusses functionalities originating from these systems. It introduces the Quality Function Deployment method and utilizes its House of Quality concept in order to develop and initially evaluate the First-Stage Prototype – the prototypical implementation of the collaborative working environment combining these two main types. The presented framework is used as a benchmarking tool on the basis of which selected existing platforms for supporting collaboration are evaluated. This research contributes to the area of the Computer-Supported Cooperative Work and discusses actual trends in development of collaborative systems related to the application of new social tools for purposes of computer-supported collaboration.Kollaborative Arbeitsumgebungen – der Gruppenbedürfnisansatz zur Entwicklung von Systemen für die Unterstützung räumlich verteilter Gruppen Die Zusammenarbeit in räumlich verteilten Gruppen erfordert technologische Unterstützung um Interaktionen innerhalb der Gruppen über Zeit und Distanz zu ermöglichen. Dabei bieten heutige Technologien verschiedene Tools zur Unterstützung von individuellen, sozialen und aufgabenorientierten Anforderungen der Gruppen. Allerdings sind viele Aspekte von computervermittelten Interaktionen nicht ausreichend erforscht und die Gestaltung von effektiven computerunterstützten Umgebungen für zusammenarbeitende Gruppen als eine Kombination dieser Tools bleibt eine Herausforderung. Die Erfüllung dieser Anforderungen erfordert die Berücksichtigung unterschiedlicher Aspekte der Gruppeninteraktionen sowohl aus sozialer als auch aus technologischer Perspektive. Die vorliegende Arbeit untersucht die sozialen und technischen Aspekte der Zusammenarbeit in räumlich verteilten Gruppen und präsentiert einen Entwicklungsansatz für Systeme zur Unterstützung der Zusammenarbeit. Zum einen gibt sie einen umfassenden Überblick über den aktuellen Forschungsstand zum Thema kooperative Gruppen und fasst dabei die drei verbundenen Elemente individuelle Bedürfnisse, Aufgabenbedürfnisse und Bedürfnisse zur Aufrechterhaltung der Gruppen unter dem Dach des Gruppenbedürfnisansatzes zusammen. Zum anderen präsentiert die Arbeit ein Entwicklungskonzept für kooperative Arbeitsumgebungen auf Grundlage dieses Ansatzes und somit eine Alternative für die Gestaltung von computerunterstützten Umgebungen für kollaborative Gruppen. Für diese Forschungsarbeit werden im Wesentlichen zwei Arten von Systemen sowie deren Funktionalitäten zur Unterstützung von kollaborativen Gruppen diskutiert – Groupware und Social Software. Um eine prototypische Implementierung einer kollaborativen Arbeitsumgebung zu entwickeln und eine erste Evaluation durchzuführen, wird die Quality Function Deployment Methode und das damit verbundene House of Quality Konzept verwendet. Die Forschungsergebnisse leisten einen Beitrag auf dem Gebiet der computerunterstützten Gruppenarbeit (Computer-Supported Cooperative Work) und diskutieren aktuelle Trends im Bereich der Entwicklung kollaborativer Arbeitsumgebungen, die sich mit der Integration von neuen sozialen Tools zum Zweck computerunterstützter Zusammenarbeit beschäftigen

Process Support for Cooperative Work on the World Wide Web

The World Wide Web is becoming a dominating factor in information technology. Consequently, computer supported cooperative work on the Web has recently drawn a lot of attention. “Process Support for Cooperative Work” (PSCW) is a Web based system supporting both structured and unstructured forms of cooperation. It is a combination of the “Basic Support for Cooperative Work” (BSCW) shared workspace system and the Merlin Process Support Environment. The current PSCW prototype offers a loose connection, in effect extending BSCW with a gateway to Merlin. With this prototype we have successfully addressed the technical issues involved; further integration of functionality should not pose any real problems. We focus on the technical side of the PSCW system, which gives a good insight into the issues that have to be addressed generally in the construction of Web based groupware

Proceedings of the ECSCW'95 Workshop on the Role of Version Control in CSCW Applications

The workshop entitled "The Role of Version Control in Computer Supported Cooperative Work Applications" was held on September 10, 1995 in Stockholm, Sweden in conjunction with the ECSCW'95 conference. Version control, the ability to manage relationships between successive instances of artifacts, organize those instances into meaningful structures, and support navigation and other operations on those structures, is an important problem in CSCW applications. It has long been recognized as a critical issue for inherently cooperative tasks such as software engineering, technical documentation, and authoring. The primary challenge for versioning in these areas is to support opportunistic, open-ended design processes requiring the preservation of historical perspectives in the design process, the reuse of previous designs, and the exploitation of alternative designs. The primary goal of this workshop was to bring together a diverse group of individuals interested in examining the role of versioning in Computer Supported Cooperative Work. Participation was encouraged from members of the research community currently investigating the versioning process in CSCW as well as application designers and developers who are familiar with the real-world requirements for versioning in CSCW. Both groups were represented at the workshop resulting in an exchange of ideas and information that helped to familiarize developers with the most recent research results in the area, and to provide researchers with an updated view of the needs and challenges faced by application developers. In preparing for this workshop, the organizers were able to build upon the results of their previous one entitled "The Workshop on Versioning in Hypertext" held in conjunction with the ECHT'94 conference. The following section of this report contains a summary in which the workshop organizers report the major results of the workshop. The summary is followed by a section that contains the position papers that were accepted to the workshop. The position papers provide more detailed information describing recent research efforts of the workshop participants as well as current challenges that are being encountered in the development of CSCW applications. A list of workshop participants is provided at the end of the report. The organizers would like to thank all of the participants for their contributions which were, of course, vital to the success of the workshop. We would also like to thank the ECSCW'95 conference organizers for providing a forum in which this workshop was possible

Mobile support in CSCW applications and groupware development frameworks

Computer Supported Cooperative Work (CSCW) is an established subset of the field of Human Computer Interaction that deals with the how people use computing technology to enhance group interaction and collaboration. Mobile CSCW has emerged as a result of the progression from personal desktop computing to the mobile device platforms that are ubiquitous today. CSCW aims to not only connect people and facilitate communication through using computers; it aims to provide conceptual models coupled with technology to manage, mediate, and assist collaborative processes. Mobile CSCW research looks to fulfil these aims through the adoption of mobile technology and consideration for the mobile user. Facilitating collaboration using mobile devices brings new challenges. Some of these challenges are inherent to the nature of the device hardware, while others focus on the understanding of how to engineer software to maximize effectiveness for the end-users. This paper reviews seminal and state-of-the-art cooperative software applications and development frameworks, and their support for mobile devices

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

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

Historical awareness support and its evaluation in collaborative software engineering

The types of awareness relevant to collaborative soft- ware engineering are identified and an additional type, "historical awareness" is proposed. This new type of awareness is the knowledge of how software artefacts re- sulting from collaboration have evolved in the course of their development. The types of awareness that different software engineer- ing environment architectures can support are discussed. A way to add awareness support to our existing OSCAR sys- tem, a component of the GENESIS software engineering platform, is proposed. Finally ways of instrumenting and evaluating the awareness support offered by the modified system are outlined
