We investigate the diversity of participatory design research practice, based on a review of ten years of participatory design research published as full research papers at the Participatory Design Conferences (PDC) 2002–2012, and relate this body of research to five fundamental aspects of PD from classic participatory design literature. We identify five main categories of research contributions: Participatory Design in new domains, Participatory Design methods, Participatory Design and new technology, Theoretical contributions to Participatory Design, and Basic concepts in Participatory Design. Moreover, we identify how participation is defined, and how participation is conducted in experimental design cases, with a particular focus on interpretation, planning, and decision-making in the design process

This article starts from the paradox that, although participation is a defining trait of participatory design (PD), there are few explicit discussions in the PD literature of what constitutes participation. Thus, from a point of departure in Actor-Network Theory (ANT), this article develops an analytical understanding of participation. It is argued that participation is a matter of concern, something inherently unsettled, to be investigated and explicated in every design project. Specifically, it is argued that (1) participation is an act overtaken by numerous others, rather than carried out by individuals and (2) that participation partially exists in all elements of a project. These traits are explicated in a design project called ‘Teledialogue’, where the participants are unfolded as networks of reports, government institutions, boyfriends, social workers and so on. The argument is synthesised as three challenges for PD: (1) participants are network configurations, (2) participation is an aspect of all project activities and (3) there is no gold standard for participation.

Social sustainability is becoming an increasingly important topic in design practice, calling for more contextual perspectives on the process of design for social sustainability. This paper presents a retrospective case study analyzing the design process of a serious game which aimed to empower teenagers to organize events to strengthen community bonds. The community context in which the collaborative project took place underwent significant contextual changes due to the COVID-19 pandemic. Analysis using the Ecologies of Contestation framework shows the influence of multiple contextual levels (Socio-cultural, Power, Constructed, and Values-based) on the design process. Moreover, the paper discusses multiple contextual factors which influenced the design process and presents four suggestions for designers to anticipate and benefit from dynamics in these contextual elements. The suggestions regard (1) integrating the temporal dimension in the collaborative design processes, (2) carefully considering (value) alignment between actors, (3) leveraging values in the collaborative design process, and (4) acknowledging and responding to the multilayered nature of communities throughout the design process. As such, this paper explores the relationships between the community context and the collaborative design process to contribute to more resilient design practices.
