I aim to strengthen Social Design inquiries by introducing lenses from Performance Studies and Design Anthropology for acquiring better understandings of how social designers navigate performative processes of practice research. I draw upon experiences in co-producing performative modes of inquiries as an everyday theatre. A design research project supporting citizens, public and private partners in different ways in which communities of senior citizens could be supported in organizing and meeting up for social and outdoor exercise activities on an ad-hoc basis. I show how knowledges is bodily co-produced and performed through multiple partners co-scripting the performance of an everyday theatre, which manifest itself in a performative praxis. I offer a performative framework that enable social designers to explore different performative modes of inquiry as approaching worldmaking as rehearsing by trickstering, performing by wayfaring and re-enacting by bartering multiple worldviews of an everyday theatre. Performance Studies and Design Anthropology has the potential to support situated experiential inquiries and portray the values for partners in practice research transitioning civic and public relations in welfare societies.
