Since the dawn of humanity design has influenced human life. Today, facing the depletion of the socio-ecological system, increasing complex problems threaten humanity’s existence. Design has been a contributor to creating such problems, yet with appropriate tools can become a source for solutions. Design Thinking (DT) was identified as a possible approach that could contribute to Strategic Sustainable Development (SSD). The purpose of this thesis is to examine potential contributors and hindrances of the DT process with regards to SSD, and create a prototype for an integrated process that could help achieve more strategic and sustainable outcomes. With the use of the Framework for Strategic Sustainable Development (FSSD) as a lens to examine the above, along with interviews, Action Research and expert feedback, an integrated process was created. Results of the interviews and FSSD analysis helped shape two prototypes that were examined through the mentioned methods. It was indicated by participants of the Action Research and by experts that the prototype could help reach a strategic and sustainable outcome, and further refinement should be pursued. The final prototype is presented as part of the discussion, suggesting additional tools and actions that if included could create a possible Sustainable DT (SDT) process.
