This paper reviews the work environment surrounding integrated office systems, synthesizes the known effects of automated office technologies, and discusses their impact on work efficiency in office environments. Particular attention is given to the effect of automated technologies on networks, workflow/processes, and organizational structure and power. Emphasis is given to structural changes due to the introduction of newer information technologies in organizations, especially the impact upon the average organization's middle ranks, which have shrunk drastically with the adoption of new methods of communication and information processing. Research projects are listed by author(s) and date together with a brief statement of the work efficiency impacts found by each study, and conclusions suggest that organizations do not achieve and maintain effectiveness by technology alone. It is recommended that integrated information technology be applied creatively to change the way organizations carry out their activities and use technology to their own competitive advantage. A list of references completes the document. (JB)
