PD meaning in Academic & Science ?

Participatory design (originally co-operative design, now often co-design) is an approach to design attempting to actively involve all stakeholders (e.g. employees, partners, customers, citizens, end users) in the design process to help ensure the result meets their needs and is usable. Participatory design is an approach which is focused on processes and procedures of design and is not a design style. The term is used in a variety of fields e.g. software design, urban design, architecture, landscape architecture, product design, sustainability, graphic design, planning, and even medicine 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.

Recent research suggests that designers create more innovative concepts and ideas when working within a co-design environment with others than they do when creating ideas on their own.

Participatory design has been used in many settings and at various scales. For some, this approach has a political dimension of user empowerment and democratization. For others, it is seen as a way of abrogating design responsibility and innovation by designers.

In several Scandinavian countries, during the 1960s and 1970s, participatory design was rooted in work with trade unions; its ancestry also includes action research and sociotechnical design.
