Building of Smart City concepts are one of the big challenges for city management. It is a completely different view of the possibilities of urban development. How to ensure better living conditions for citizens? How to make a city more friendly to visitors? How to create an innovative business development environment? How not to get stuck in the trap of various vendors who have only one goal, to sell their products? These questions are posed by many mayors. The vast majority of them are not experts in Smart City concepts, and the offer of different “smart” solutions is unclear to them. Czech Smart City Cluster was created precisely to help these mayors find the right, conceptual solutions. He created the "Smart City Building Methodology" that describes these areas. How to create an introductory concept. How to describe the basic vision of a concrete intelligent city, How to analyze partial areas in a strategic city development plan and involve citizens in public discussion. What is the steering committee and what role it plays. What action plans are used for. What is a project stack. That the basis of a full-fledged concept is integration sub-areas into a common environment. When and under what conditions is possible safely proceed with the implementation of projects. And that the entire Smart City program needs to be continually evaluated and updated.
