This document discusses combining social and digital technology with STS-D (socio-technical system design) principles to support cross-disciplinary designing. It proposes that organization designers, ICT designers, and facilities designers collaborate to design at the intersection of their domains. When all users participate meaningfully in the design process and the organization, ICT systems, and facilities are designed concurrently using STS principles, benefits include better customer experiences, staff experiences, and business outcomes, as well as lower costs and increased agility. STS principles and new digital and social technologies can provide the "glue" to enable this cross-disciplinary designing approach.
