  18. 18. Program Design Service Design System Design Practice Design Foundation Design
  19. 19. What do consumers need to use the service for? What interactions are needed to support those tasks? What qualities does the service need to support the tasks? How will the service be implemented (reuse existing, modify existing, build new)?
  20. 20. What is the scope of the system of microservices? What service domains are involved? What services are required? What non-functional domains are involved (security, service levels, more)?
  21. 21. What technological capabilities are needed to support the system of microservices? How will these capabilities be implemented? Using which technologies? What standards and guidelines need to be put in place?
  22. 22. What are your goals for moving to a microservice architecture? What are the main obstacles to this change? What are your core microservice principles? What is needed to build momentum for the change?
  23. 23. What practices need to be adopted in order to deliver the system of microservices? What institutionalized organizational practices need to be used for the delivery of the microservices system? What organizational blind spots need to be addressed? How can adaptability be incented in the organization?
