Smart cities have gained attention recently as a means of addressing the complex and diverse urban problems. Smart city initiatives are regarded as a systematic transformation to a sustainable city through the design and implementation of a digital service system (DSS) that offers functionality to citizens through the holistic integration of digital technology, urban assets, and physical products. However, DSS implementation often conflicts with current social norms and customs owing to the lack of consideration of the social and human aspects of the target city. This study developed a conceptual framework for the strategic design and implementation of DSS in smart cities. Specifically, technology roadmapping (TRM) is adopted as a core technique. This study suggests DSS roadmapping framework that modified TRM to enable strategic planning of DSS through expressing the interaction between technology and social aspect based on the requirements to be considered in its design and implementation.
