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

Groupware and the simulation consultant

The paper recognises that good communication and interaction are key factors to the success of a simulation project and suggests that groupware technology can increase the chances of success. To underline this, the paper reviews the process of simulation to illustrate the amount of communication and interaction that must take place during a simulation project. The paper then discusses computer supported cooperative work and groupware, a research field and information technology that has successfully supported communication and interaction in other industries. To illustrate how groupware may by used by the simulation consultant, net-conferencing, exemplified by Microsoft's NetMeeting, is presented. The paper ends with some observations on the future of these applications in simulation modelling

Evaluating groupware support for software engineering students

Software engineering tasks, during both development and maintenance, typically involve teamwork using computers. Team members rarely work on isolated computers. An underlying assumption of our research is that software engineering teams will work more effectively if adequately supported by network-based groupware technology. Experience of working with groupware and evaluating groupware systems will also give software engineering students a direct appreciation of the requirements of engineering such systems. This research is investigating the provision of such network-based support for software engineering students and the impact these tools have on their groupwork. We will first describe our experiences gained through the introduction of an asynchronous virtual environment ­ SEGWorld to support groupwork during the Software Engineering Group (SEG) project undertaken by all second year undergraduates within the Department of Computer Science. Secondly we will describe our Computer Supported Cooperative Work (CSCW) module which has been introduced into the students' final year of study as a direct result of our experience with SEG, and in particular its role within Software Engineering. Within this CSCW module the students have had the opportunity to evaluate various groupware tools. This has enabled them to take a retrospective view of their experience of SEGWorld and its underlying system, BSCW, one year on. We report our findings for SEG in the form of a discussion of the hypotheses we formulated on how the SEGs would use SEGWorld, and present an initial qualitative assessment of student feedback from the CSCW module

Groupware design : principles, prototypes, and systems

Computers are valuable tools for a wide range of work tasks. A substantial limitation on their value, however, is the predominant focus on enhancing the work of individuals. This fails to account for the issues of collaboration that affect almost all work. Research into computer supported cooperative work (CSCW) aims to eliminate this deficiency, but the promise of computer systems for group work has not been met. This thesis presents four design principles that promote the development of successful groupware. The principles identify the particular problems encountered by groupware, and provide guidelines and strategies to avoid, overcome, or minimise their impact. Derived from several sources, the major influence on the principles development is an investigation into the relationship between factors affecting groupware failure. They are stimulated by observations of groupware use, and by design insights arising from the development of two groupware applications and their prototypes: Mona and TELEFREEK. Mona provides conversation-based email management. Several groupware applications allow similar functionality, but the design principles result in Mona using different mechanisms to achieve its user-support. TELEFREEK provides a platform for accessing computer-supported communication and collaboration facilities. It attends to the problems of initiating interaction, and supports an adaptable and extendible set of "social awareness" assistants. TELEFREEK offers a broader range of facilities than other groupware, and avoids the use of prohibitively high-bandwidth communication networks. TELEFREEK demonstrates that much can be achieved through current and widely accessible technology. Together, Mona and TELEFREEK forcefully demonstrate the use of the design principles, and substantiate the claim of their utility

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

Trabajo cooperativo con Computadora (CSCW) Aplicado en plataforma de Enseñanza-Aprendizaje NEXUS de la UANL

Resumen: Groupware y Computer-Supported Cooperative Work (Trabajo cooperativo con Ordenador CSCW) son términos que se refieren al trabajo entre grupos de personas que colaboran entre sí mediante redes de computadoras; estos conceptos están incluidos como objetos de estudio del área de la Interacción Humano Computadora. Debido a que un grupo de alumnos que cursa una clase a distancia forma parte, junto con su profesor o facilitador, de un entorno de trabajo colaborativo en línea, los términos de Groupware y CSCW se aplican en las plataformas de enseñanza aprendizaje. En este trabajo se muestra un análisis de NEXUS, que es la Plataforma Institucional de Enseñanza Aprendizaje de la UANL, con la finalidad de evaluarla con respecto a los diferentes aspectos que debe cubrir para lograr que el Groupware trabaje eficientemente según las características definidas para un CSCW. Summary: Groupware and Computer-Supported Cooperative Work are terms referred to work between groups of people that collaborate with each other through computer networks; moreover these concepts are considered as object of study of the area of Human Computer Interaction. Since a group of students that take a distance education course is part, along with its professor or facilitator, of an online collaborative work environment, the terms Groupware and CSCW are applied on teaching and learning platform. In this work, NEXUS, which is the Institutional Education Platform, is analyzed with the purpose of evaluating it with respect to the different aspects that it should cover in order to make that the Groupware work efficiently according to the characteristics defined for a CSCW

Integrating Groupware Activities into Workflow Management Systems

Computer supported cooperative work (CSCW) has been recognized as a crucial enabling technology for multi-user computer-based systems, particularly in cases where synchronous human-human interaction is required between geographically dispersed users. Workflow is an emerging technology that supports complex business processes in modern corporations by allowing to explicitly define the process, and by supporting its execution in a workflow management system (WFMS). Since workflow inherently involves humans carrying out parts of the process, it is only natural to explore how to synergize these two technologies. We analyze the relationships between groupware and workflow management, present our general approach to integrating synchronous groupware tools into a WFMS, and conclude with an example process that was implemented in the Oz WFMS and integrated such tools. Our main contribution lies in the integration and synchronization of individual groupware activities into modeled workflow processes, as opposed to being a built-in part of the workflow WFMS

GTA: Groupware task analysis Modeling complexity

The task analysis methods discussed in this presentation stem from Human-Computer Interaction (HCI) and Ethnography (as applied for the design of Computer Supported Cooperative Work CSCW), different disciplines that often are considered conflicting approaches when applied to the same design problems. Both approaches have their strength and weakness, and an integration of them does add value to the early stages of design of cooperation technology. In order to develop an integrated method for groupware task analysis (GTA) a conceptual framework is presented that allows a systematic perspective on complex work phenomena. The framework features a triple focus, considering (a) people, (b) work, and (c) the situation. Integrating various task-modeling approaches requires vehicles for making design information explicit, for which an object oriented formalism will be suggested. GTA consists of a method and framework that have been developed during practical design exercises. Examples from some of these cases will illustrate our approach

Current Usage and Potential of Computer Supported Cooperative Work in Swiss Banks: An Empirical Study

The results presented in this paper are part of an empirical study into the current usage of groupware and the potential of Computer Supported Cooperative Work (CSCW) for strategic management in large-scale Swiss business enterprises. The results were obtained from a survey conducted among 168 organizations. The study is part of the STRATUM research project, the overall goal of which is to investigate and evaluate methods, techniques and tools to support cooperative activities in strategic management groups. Due to the importance of the banking sector in Switzerland and the high response rate from the bank sample, we present here results related to this sector of industry

Evaluation of the influence of personality types on performance of shared tasks in a collaborative environment

Computer Supported Cooperative Work (CSCW) is an area of computing that has been receiving much attention in recent years. Developments in groupware technology, such as MERL’s Diamondtouch and Microsoft’s Surface, have presented us with new, challenging and exciting ways to carry out group tasks. However, these groupware technologies present us with a novel area of research in the field of computing – that being multi-user Human-Computer Interaction (HCI). With multi-user HCI, we no longer have to cater for one person working on their own PC. We must now consider multiple users and their preferences as a group in order to design groupware applications that best suit the needs of that group. In this thesis, we aim to identify how groups of two people (dyads), given their various personality types and preferences, work together on groupware technologies. We propose interface variants to both competitive and collaborative systems in an attempt to identify what aspects of an interface or task best suit the needs of the different dyads, maximising their performance and producing high levels of user satisfaction. In order to determine this, we introduce a series of user experiments that we carried out with 18 dyads and analyse their performance, behaviour and responses to each of 5 systems and their respective variants. Our research and user experiments were facilitated by the DiamondTouch – a collaborative, multi-user tabletop device
