The focus of this paper is participatory design (PD); a field that has been in existence since the 1960s. Reflections on a PD project in which the author played a central role revealed that existing literature does not engage adequately with intersubjective decision-making in PD processes. In this paper, appropriation and re-imagination of the Nordic framework for performance-based standards results in a novel multidimensional schema with five mutually related steps. Analysis indicates that the schema has a capacity for enhancing intersubjectivity in PD decision-making while also rendering the process more malleable to multiple viewpoints and their fusion into progressively definitive shared outcomes. In the conclusions, prospects for projective and reflective application of the schema explore its transformative capacity for professional and lay participants and its potential role in engendering critical design pedagogy.
