Technological growth has amplified the possibilities and necessity for collaboration across geographic borders. The sociotechnical systems which arise from and are developed to support such collaboration must transcend national boundaries, cultures and organisations. This paper is a response to the question of how we can make such sociotechnical systems flexible, sustainable and participative. To this end, we use infrastructuring (a mode of participatory design) as a theoretical framework for an action research intervention into the development of a Learning Management System (LMS) to support collaboration between Australian and Chinese universities. Based on our findings, we propose interweaving the concepts of infrastructuring and publics as an innovative, synergistic theoretical response to the challenges of implementing sociotechnical systems in a global context.
