Service science is an emerging field, but many still consider it lacking in substance. This book aims to change the situation by addressing the following questions: What is the big story about service? What are the main research problems in service? What does "a connected world" mean? Does service require a different kind of design science? What will be the next waves of the Web? How to support universal value co-creation? How to unite Cyberspace wilt physical space? Is it feasible to connect information resources everywhere?To answer these questions, the book presents and substantiates a digital connections scaling (DCS) model, complete with a population-oriented design paradigm and a new class of microeconomic production functions to explain the paths of transformation into the future - one of the most original results today. Next, the book analyzes new business designs on the Web and characterizes a service-led revolution for the Knowledge Economy. Thirdly, it develops systems planning and design methods to help implement the DCS model at the level of Information and Database Systems, Business Strategy, and Digitization Engineering, thereby enhancing these fields. Finally, certain intriguing new applications, especially "smart highways" and information supply chains, are discussed.
