Human activities are now so pervasive and profound that they are altering the stability of the earth in ways that threaten the very life support system upon which humanity depends. The field of design has contributed to the creation of such complex socio-ecological problems, but it is also adapting as a source for solutions. Design Thinking (DT) was identified as a possible approach that could help create such solutions, and contribute to Strategic Sustainable Development (SSD). The purpose of the research was to examine potential contributors and hindrances of the DT process with regards to SSD, and create a prototype of an integrated process that could help achieve more strategic and sustainable outcomes. Using the Framework for Strategic Sustainable Development (FSSD) as a lens to examine and inform the above, combined with interviews, Action Research and expert feedback, an integrated process was created. It was indicated by participants of the Action Research and by experts that the proposed prototype could help reach strategic and sustainable outcomes, and that further refinement should be pursued. Consequently, a third and final prototype, suggesting a possible Sustainable Design Thinking (SDT) process, was developed. (C) 2015 Elsevier Ltd. All rights reserved.
