What is a Smart City?
• Technology?
• ICT?
• Data?
• Smarter Planning?
• Smarter Operation?
• Smarter Organization?
• Smarter People?

3. 3
What is a Smart City?
• Many definitions depending on view, role, discipline, sector,
domain, country, …
• Combination of physical world, services, infrastructure, ICT
• Dimensions of technology, people, institutions
A Smart City is a dynamic complex socio-technical system-of-
systems that integrates information and communication
technology into its structure to manage and improve its
planning, services, and operations towards a livable city.

Quadruple Helix Innovation Model
• Method used in Innovation,
Urban Planning/Development,
Citizen engagement
• Co-Creation and Open
Innovation
• Involvement and collaboration
of relevant actors
• Structural changes beyond any
one segment
• Smart city means involvement of
all stakeholders in urban
innovation, knowledge sharing,
collaboration

Handling Complexity
• Smart City ➞ Smart City Development and Evolution
• Cities are complex
• Integrated interoperable solutions are hard (not only ICT)
• Goal: Keep flexibility, enable experimentation
• Trondheim: > 200 IT systems in the administration alone
(including legacy), does not include connection to physical
systems, physical asset management and automation,
external departments (health, …), subcontractors, national
systems, needs of future SC/IoT/BigData projects

16. 16
Refined Smart City Understanding through EA
• The city is a complex ICT-heavy socio-technical enterprise
ecosystem
• A Smart City is not a project or a state, it is a process
– At least a suite of complexly connected projects and environments and
dynamics
• Smart City can mean the City ‘reinventing’ itself
• Ongoing restructuring and digitalization processes
– Service innovation
– System/services integration and connection
– New technology, connecting silos
