The TANGO e-government arena is a project in Southern Sweden, funded by the Innovative Actions of the European Regional Development Fund. The project is now nearing its end, and we are thus at the stage of reflectively reviewing what has actually been accomplished and how this relates to the original goals of the project. In July 2002, when the project began, the aim was to establish cooperation between the public sector, private enterprise and university-based research in designing public e-services. 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 have aimed towards establishing 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 research questions have focused on exploring and managing multi-perspectivity as a resource for design. In this paper we look at how we organized our cooperation around these goals, and attempt to address those basic summing-up-the-project questions; How well have we succeeded? What have we learned in the process?
