6 Service Design & Ecosystem Meta Journeys

Draft abstract: this chapter converts the canvas from Chapter 4 into stakeholder alignment journeys and system sequence diagrams (rendered code in 付録 B).

service design · meta-journey mapping · stakeholder interaction · API/data exchange

6.1 5.1 Stakeholder Interaction Vectors

Government, industry, and academia touchpoints; who owns which handoff.

6.2 5.2 API and Data Exchange Nodes

Where the meta-journey requires machine-to-machine exchange versus human sign-off.

6.3 5.3 Sequence Modeling of Institutional Workflows

Reading and adapting the Mermaid sequence diagram in 付録 B (Section B.2) for a new institutional context.

Bridge to Chapter 6

Chapter 6 stress-tests these journeys against real de-risking cases using the Safe and Sustainable by Design (SSbD) matrix.
