Cities integrate systems for coordinated services

  • Integration usually happens within isolated domains
  • In smart cities, systems integrators build, coordinate, and advise
  • Urban IoT highlights opportunities for back-office integration

Smart city integration prevents new silos

  • Smart city systems come together in bits
  • Pulling systems together can cut duplication costs

Genuinely integrated smart cities are a way off

  • Competition funding creates "more pilots than British Airways"
  • The business case for smart city integration is still weak
  • Smart city integration poses both risks and benefits to security
  • It is hard to integrate things that are owned by different people

Integration supports data-driven decisions

  • Most smart city projects are about data, not control
  • Integration is about working practices as well as systems
