Computer Supported Co-operative Work (CSCW) and Groupware
“Computer-supported cooperative work or CSCW is computer-assisted coordinated activity carried out by groups of collaborating individuals.” (Baecker 1995, p. 141)
“Groupware is distinguished from normal software by the basic assumption it makes: groupware makes the user aware that he is part of a group, while most other software seeks to hide and protect users from each other ... Groupware ... is software that accentuates the multiple user environment, coordinating and orchestrating things so that users can “see” eachother, yet do not conflict with each other.”
(Lynch 1990, p. 160, in Baecker 1995, p. 141)
Types of CSCW
Primarily for communication
Electronic mail (email)
Structured email — computer conferencing (Netnews, newsgroups, bulletin boards) messages organised by topic, and sometimes mediated by a convenor.
Teleconferencing — the use of audio and video links.
Joint problem solving
Collaborative writing or drawing.
Group decision support systems (GDSS) — the electronic meeting room.
Where shared interpersonal communications spaces are integrated with shared task workspaces.
“... applications written to support the collaboration of several users.” (Dix 1998, p. 463)
Groupware can be classified in several ways:
by where and when the individual participants perform the cooperative work - summarised in a time/space matrix.
by the function of the system — e.g., collaborative design, group authoring, meeting support, etc.
by the structural support function of the software
computer-mediated communication — where direct communication between participants is supported.
meeting and decision support systems — where common understandings are captured.
shared applications and artefacts — where the participants’ interaction with shared work object (the artefacts of work) are supported.
(Dix 1998, pp. 466-7. Chapter 13 uses this classification.)
Other issues involve; group size, multiple individual sites verses multiple group sites, and the predictability of time and space component.
“Asynchronous groupware supports communication and problem solving among groups of individuals who contribute at different times, and typically also are geographically dispersed.”
(Baecker 1995, p. 743)
Organises access by name of recipient.
May be addressed to multiple receivers (broadcast email, mailing lists).
Problems with etiquette, spam, overabundance of email, difficulty locating information in huge database of conference messages..
Issues of authority, control and influence.
BSCW (Basic Support for Cooperative Work): A Web based product that attempts to do what its name implies.
One meeting site
Multiple meeting sites
The Meeting object assists in organising face-to-face meetings.
By the use of the Monitor applet (not currently installed here).
Can be integrated with video conferencing systems (e.g., CU-SeeMe) to set up meetings.
Same as cell on right -->
Holds all documents, etc., associated with the project in a workspace.
Reports modifications to the workspace.
Bulletin board, with some support for rhetorical structure.
