In Scandinavia we have for two decades been concerned with participation and skill in the design and use of computer-based systems. Collaboration between researchers and trade unions on this theme, starting with the pioneering work of Kristen Nygaard and the Norwegian Metal Workers’ Union, and including leading projects like DEMOS and UTOPIA, has been based on a strong commitment to the idea of industrial democracy. This kind of politically significant, interdisciplinary, and action-oriented research on resources and control in the processes of design and use has contributed to what is often viewed abroad as a distinctively Scandinavian approach to systems design. This Scandinavian approach might be called a work-oriented design approach. Democratic participation and skill enhancement, and not only productivity and product quality, are themselves considered objective of design. [Based on the two research projects, DEMOS and UTOPIA, I have elaborated this approach in detail in Work-Oriented Design of Computer Artifacts (1989). This paper is based on that work.] Two important features of participatory design shape its trajectory as a design strategy. The political one is obvious. Participatory design raises questions of democracy, power, and control in the workplace. In this sense it is a deeply controversial issue, especially from a management point of view. The other major feature is technical—its promise that the participation of skilled users in the design process can contribute importantly to successful design and high-quality products. Some experiences, perhaps most developed in Scandinavia, support this prediction and contribute to the growing interest in participatory design in the United States and other countries; by contrast, “expert” design strategies have too often turned out to be failures in terms of the usability of the resulting systems. These two features together suggest that there should be a strong link between the skill and product quality aspect of user participation and the democracy and control aspect, or else participatory design will be a deeply controversial issue from the point of view of the employees and trade unions. The trade-union-oriented democracy aspect of skill and participation in design is discussed in the first part of the chapter.
