  • What is CSCW?In its most general form, CSCW examines the possibilities and effects of technological support for humans involved in collaborative group communication and work processes. (Bowers, J. and S. Benford 1991)

    Greif defines CSCW as computer-assisted coordinated activity such as communication and problem solving carried out by a group of collaborating individuals (Greif 1988).

  • What is CSCW?What is CSCWThe field was coined in the 1980th by researchers from computer science, information science and social science.Interdisciplinary field where researchers are from various fields contribute with different perspectives and methodologies for acquiring knowledge of group work and for suggesting how the groups work could be supported. E.g., computer scientists, social scientists, psychologist, cognitive scientists, etc.Two sides of CSCW: Group work and social phenomena. The technology and computer hardware and software

  • CSCWCSCW should be conceived as an endeavor to understand the nature and characteristics of cooperative work with the objective of designing adequate computer-based technologies. CSCW is a research area addressing questions like the following: What are the specific characteristics of cooperative work as opposed to work performed by individuals in seclusion? How can computer-based technology be applied to enhance cooperative work relations? How should designers approach the complex and delicate problems of designing systems that will shape social relationships? And so forth. The focus is to understand, so as to better support, cooperative work.

  • GroupwareDefinition (Ellis et al. 1991)Groupware are computer-based systems that support groups of people engaged in a common task (or goal) and that provide an interface to a shared environment.

  • GroupwareGroupware can support different activitiesDirect interpersonal communicationIdeas generation and decision makingSharing computer objects

  • CSCW v.s. GroupwareCSCW v.s. GroupwareGroupware is the product (program) resulting from the research done in the CSCW field.CSCW as a research field will persist, because it addresses larger questions about the design and refinement of groupware.

  • CSCW v.s. GroupwareCSCW:Focus onworkplace activities,organizational impact of technology,co-evolution of the technology and the groups using it,Interdisciplinary: Social scientists and technologists.Groupware:Focus oncomputer systems,the design of the computer systems,Mainly a technical discipline: technologists
