Collaborative software is a concept that greatly overlaps with computer-supported cooperative work (CSCW). Some authors argue they are equivalent. According to Carstensen and Schmidt (1999)[1] groupware is part of CSCW, since CSCW addresses "how collaborative activities and their coordination can be supported by means of computer systems.
Software systems such as email, calendaring, text chat, wiki, and bookmarking belong to this category. It has been suggested that Metcalfe's law — the more people who use something, the more valuable it becomes — applies to these types of software.
Whereas the more general term social software applies to systems used outside the workplace, for example, online dating services and social networks like Friendster, Twitter and Facebook, the use of collaborative software in the workspace creates a collaborative working environment (CWE). A collaborative working environment supports people in both their individual and cooperative work thus giving birth to a new class of professionals, e-professionals, who can work together irrespective of their geographical location.
Finally collaborative software relates to the notion of collaborative work systems which are conceived as any form of human organization that emerges any time that collaboration takes place, whether it is formal or informal, intentional or unintentional[2].
Whereas the groupware or collaborative software pertains to the technological elements of computer supported cooperative work, collaborative work systems become a useful analytical tool to understand the behavioral and organizational variables that are associated to the broader concept of CSCW.[3]
Groupware
The term groupware can be traced as far back as the late 1980s, when Richman and Slovak (1987)[10] wrote:"Like an electronic sinew that binds teams together, the new groupware aims to place the computer squarely in the middle of communications among managers, technicians, and anyone else who interacts in groups, revolutionizing the way they work."
In the early 1990s the first groupware commercial products began delivering up to their promises, and big companies such as Boeing or IBM started using electronic meeting systems to leverage key internal projects. Lotus Notes appeared as a major example of that product category, allowing remote group collaboration when the Internet was still in its infancy. Kirkpatrick and Losee (1992) [11] wrote then: "If GROUPWARE really makes a difference in productivity long term, the very definition of an office may change. You will be able to work efficiently as a member of a group wherever you have your computer. As computers become smaller and more powerful, that will mean anywhere."
As collaborative software evolves and migrates into the Internet itself, it contributes to the development of the so called Web 2.0 bringing a host of collaborative features that were originally conceived for within the corporate network. These include functionalities such as document sharing (including group editing), group calendar and instant messaging, web conferencing, among others. The study of computer-supported collaboration includes the study of collaborative software and social phenomena associated with it.
