The CSCW technology enables a flexible design of the organisation compared with the old technology. New organisation forms emerge that are flexible, boundless and process-oriented. In this article a case study is presented of the development and test of a prototype in Lotus Notes for dealing with social insurance matters within the Swedish Social Insurance Board. The focus of the case study is on integration of work organisation aspects into the development process of CSCW systems. The design of the technology and the organisation could affect the work organisation of the individual as well as efficiency and quality aspects. Scenarios are proposed as a technique for discussion and design of the future work organisation of CSCW systems.
