Applying Design Thinking in Systems Engineering Process as an Extended Version of DIKW Model

Systems engineering methodology has expanded its application fields into creating innovations and designing societal systems. In the present age, where everything has increased in complexity, systems engineers are challenged to solve ill‐defined problems to create innovations and to design societal systems. Design thinking has attracted attention as a methodology for solving ill‐defined problems. However, design thinking cannot create innovations or design societal systems by itself. It is effective when it is applied to the systems engineering process, and embedded in its processes. This paper proposes using the advantages of both design thinking and systems engineering to build the Structured Design Thinking Framework as an extension to the DIKW model. The framework has integrated the non‐structured design thinking process and the structured systems engineering process. We used this framework to redesign a local community in Japan and to design a new concept of aquarium, and confirmed that this framework works.
