Activity Theory

Arguments for using Qualitative methods in Computer Science

The 'soft' side of computer related research relates to people. There is not only a great diversity amongst people in general, but also many subtleties relating to the specific context in which they relate to technologies. Any computer system becomes part of a socio-technical system when in use, and this is most evident with tools which facilitate collaborative or social interaction. Trist (The evolution of socio-technical systems, 1981) identifies three levels at which socio-technical systems have to be investigated:

Primary work systems - these relate to systems which work in a bounded environment, for instance the people and tools involved in producing a particular academic paper or proposal. These have a specific purpose, which provides a focus for the people and activities.

Whole organization systems - these can be self-contained workplaces, such as a workgroup which deals with end to end production of a resource, or entire businesses or organisations. Trist describes them as persisting "by maintaining a steady state within their environment"

Macrosocial systems - these include systems in communities, and which operate at a societal level. Trist calls these 'domains'.
