This book explains the design thinking approach both for designing new services and delivering the services. This approach itself can be applied to areas other than pure services, because it contains the innovative and intrinsic ingredients that can be applied to any human activity. Chapter 1 introduces mindset and preparation for service design. Introduction on design thinking and design thinking toolkits are provided in Chapter 2, which you can try in your service. Both IDEO's Design Thinking for Educators Toolkit and Innovation Leadership Board's Playbook for Strategic Foresight and Innovation are discussed in detail. Chapter 3 provides a societal approach which is often neglected in the service design. A short break is provided at Chapter 4, entitled "Intermezzo," summarizing the contents of preceding chapters and presenting additional and refreshing perspectives on service design with the design thinking approach. Prototyping and testing the service design is the theme of Chapter 5. Chapter 6 provides some case studies so that you can check what you have learned. I picked up real cases from local areas. In Chapter 7, we summarize the contents of this book. The summary and conclusion can be used as a quick reference for the contents of the book.
