The TANGO e-government arena is an on-going project in Southern Sweden, funded by the Innovative Actions of the European Regional Development Fund. The aim of the project is to establish cooperation between the public sector, private enterprise and university-based research in designing public e-services. Our starting point is e-government understood as co-construction of technology, society and citizenship in everyday life. This approach is based on the Scandinavian Tradition of Participatory Design, but also motivated by on-going technological development. In cooperating around development of new, integrated services, catering to various categories of users as well as to a growing diversity of mobile technologies, we are aiming to establish feedback channels between practice and theory, between use and design, and between different academic disciplines where we see a need to synchronize the models and methods we work with. Our current research questions focus on exploring and managing multi-perspectivity as a resource for design.
