Mh. Partecipatory design?

Participatory design is an approach to design that attempts to actively involve the end users in the design process to help ensure that the product designed meets their needs and is usable. It is also used in urban design, architecture, landscape architecture and planning as a way of creating environments that are more responsive and appropriate to their inhabitants and users cultural, emotional, spiritual and practical needs. It is one approach to placemaking. It has been used in many settings and at various scales, and in the United Kingdom is known as community architecture. It is important to understand that this approach is focused on process and is not a design style. For some, this approach has a political dimension of user empowerment and democratisation. For others, it is seen as a way of abrogating design responsibility and innovation by designers. In several Scandinavian countries of the 1960s and 1970s, it was rooted in work with trade unions; its ancestry also includes Action research and Sociotechnical Design.
