The authors reflect on this recent transformation in the practice, role and skills of designers, by organising their book into three main sections. The first section links "Design for Services" to existing models and studies on services and service innovation. Section two presents multiple service design projects to illustrate and clarify the issues, practices and theories that characterise the discipline today; using these case studies the authors propose a conceptual framework that maps and describes the role of designers in the service economy. The final section projects the discipline into the emerging paradigms of a new economy to initiate a reflection on its future development.
