摘要:

We argue that the computerized information system should not look like a system on its own. Rather, it should be conceived as an inherent part of the work of its users. We therefore introduce the concept of an embedded system, which describes work tasks and organization. Computer‐supported information tasks are embedded in this environment: They are not parts of a system separated from other activities. This concept is based on the experiences gained during the development of a user‐interface prototype, derived from a theoretical frame of reference, called act orientation, to information systems, in which all computerized tasks are interpreted as acts performed by the actual user. Our suggestion continues the tradition of on‐line help and support, reaching radically deeper than usual in related approaches. We expect that our suggestion will, when applied, improve the control, productivity, quality of the outcome of work, and quality of working life, assessed from the user's point of view.

摘要:

Collaboration is at the heart of the academic enterprise; proposals for systems such as the National Science Foundation's “National Collaboratory”; or Apple Computer's “Knowledge Navigator”; seek to support these collaborative efforts by means of a variety of computing technologies. We examine the assumptions of the model of collaborative work behind such proposals and suggest ways to extend that model. We draw on a case study of collaborative efforts in classical scholarship in order to explore more fully the existing modalities of academic collaboration as it actually occurs. The development of a broader understanding of collaborative activities will enable us to address more effectively the challenge of constructing systems to support collaborative work.

摘要:

Group Support Systems may be “distributed”; for nonsimultaneous use by being embedded in a Computer‐Mediated Communication System (CMCS). In this manner, large groups may use them for complex tasks over an extended period of time. Will executives use such systems, and what are their reactions? This case study of elites engaged in formulating recommendations for the White House Conference on Productivity demonstrates that executives can use such systems, given that “critical success factors”; are met. Perceived information richness is strongly correlated with perceptions of productivity enhancement as a result of system use.
