2. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Background • Focus on “social innovation” (e.g., Manzini 14; Mulgan+ 07) ◦ Design for social innovation is required to achieve the sustainable society • “Digital tech” in service systems (e.g., Pekkala&Spohrer 19) ◦ Integrating advanced digital technologies with services is becoming important to increase the value and competitiveness ◦ Digital service also provide opportunities to address complex social issues • Smart city ◦ It originally aimed to overcome (urban) social issues using digital tech and services ◦ However, there are many criticisms on its technocentric approach that lacks a human-centered and social perspectives (Andreani+ 19) © 2023 AIST 2
3. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil SD focusing on “social” & “digital” aspects • Design for social transformation ◦ Transition Design (Irwin 18): design approach to achieve social transformation toward a desirable future. Stakeholders are involved in future visioning and the long-term interventions ◦ Transformative SD (Sangiorgi 11), SD for social innovation (Yang&Sung 16): a participatory action research to implement the transformative interventions for achieving social change • Service System + Digital tech ◦ New system concepts: Smart service system (Lim&Maglio 18), Smart PSS (Valencia+ 15), Digital service system (Watanabe+ 20) ◦ Design methods: Developed mainly in Sys. Eng. and PSS research arena (e.g., Halstenberg+ 19; Li&Lu 21; Tsunetomo+ 22) Research gap: These two approaches, design for social transformation and DSS design, have been dealt with separately and rarely intersected, although they are key to social innovation © 2023 AIST 3
4. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Objective and research approach • Approach: Design Research Methodology (Blessing&Chakrabarti 09) 1. Develop a design method: “Digital Future Design Method” to support the creation of the DSSs for realizing the social transformation to a desirable future vision 2. Apply the method to a design practice: the design of next-generation smart mobility services in the Kashiwa-no-ha Smart City in Japan 3. Reflect the application results: discussion on the usefulness and limitation of the proposed method based on the application results © 2023 AIST 4 Objective of this study is… To develop a new design method that integrates the social transformation approach with the DSS design approach
5. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Digital Future Design Method (DFDM) © 2023 AIST 5 Designed from the comprehensive perspectives of the socio cyber-physical- system (Rijswijk+ 21) <Core principle> DFDM begins with visioning the desirable future society, and then embodies the DSS concepts. Digital Social Physical Collaborative Design Design Models Refer Support Designed with collaborative approach supported by several design models

Rio de Janeiro, Brazil Proposed design process and models © 2023 AIST 6 Detailed design, Prototyping, Experiments, etc. Step1: Multi-perspective context analysis Collaborative Model-based Step2: Future visioning Collaborative Model-based Step3: Vision-based concept design Collaborative Model-based Digital Future Hexagon for the analysis of Socio-CPS context Future Life Snapshots for ideating ang analyzing possible future life scenes Vision-Life- Function Model to structure the relations between vision, life scenes, and DSS functions
7. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Application case • A project to design next-generation smart mobility services (MaaS) in the Kashiwa-no- ha Smart City (incl. Level-4 automated buses, various personal mobility vehicles, etc) • How to design future mobility services in relation to various components such as user values, urban resources, vision, and other domain services ? © 2023 AIST 7 Restaur ant Shopping center Street Mobility data City vision Mobility vehicles Automated bus Personal mobility vehicle Kashiwa-no-ha smart city Users
8. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Social Physi cal Digi tal Step1: Multi-perspective Context Analysis • DFDM begins with Digital Future Hexagon, a multi-perspective context analysis based on the socio- CPS domains: (social, physical and digital) before future visioning and DSS concept generation © 2023 AIST 8 Life with various shared mobilities to allow comfortable transportation without private cars Walkable city Comfortable city life without a private cars Shopping/resta urant services Shopping center Personal mobility vehicles Eco-friendly transportation Mobility reservation Mobility management system Personal mobility availability Personal mobility occupancy data
9. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Step2: Future visioning © 2023 AIST 9 • Images of desirable future society (future life snapshot) are envisioned based on the hexagon; then, the snapshots are summarized to created a future vision. Ideating the future life snapshots Integrating to create a future vision 1 2
10. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Step3: Vision-based concept design © 2023 AIST 10 • Designers explore and describe DSS concept (as a set of key functions) Vision Life DSS Functions Abstract Concrete Zig-zag thinking
11. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Findings • Usefulness ◦ DFDM is useful for the integrated design of two systems that have different levels of abstraction: future vision and DSSs ◦ The hexagon’s six perspectives provide “constraints” and “clues” in DSS idea generation -> effective in supporting creative thinking to explore new opportunities ◦ The design models was useful in supporting co-creation by visualizing and managing the results of workshops and discussions • Limitations ◦ This study only covers the early phases (i.e., the conceptual design) ◦ We need to apply it to other cases for verifying general usefulness © 2023 AIST 11
12. ServDes2023 | 11th-14th, July, 2023. Rio de Janeiro, Brazil Concluding summary • We propose the DFDM, a novel design method that supports the designing of DSSs for realizing the social transformation to a desirable future ◦ Design models (Digital future hexagon, VLF diagram) and design processes • The method was applied to a case of smart mobility service design • We found the method is effective in … ◦ Supporting integrated thinking of different levels of abstraction: future vision and DSSs ◦ Providing stimulus (constraints and clues) in DSS idea generation ◦ Supporting co-creation activities by visualizing and managing the results of workshops and discussions • Future works will include … ◦ Development of additional method for designing more detailed DSS architecture ◦ Application to other domain cases © 2023 AIST 12
