Is sustainable development enough for our cities?

Measuring development is challenging. Stiglitz, Fitoussi and Durand point out (Beyond GDP. Measuring What Counts for Economic and Social Performance, OECD, Paris 2019) that new measures are needed to help protect people from possible shocks, and restore a sense of security and trust in anti-crisis policies. It is also necessary to change the way we think about what is a component of well-being. The subject of the research is the city as an organization, the phenomenon which is a home for almost 60% of the population. The work is based on the following assumptions:Organizations can be thought of as a system, which means that the connections between the components of the system must be taken into account when making changes to the organization.All organizations operate under the influence of the environment, therefore problems related to functioning and development must be considered taking into account the relationship with the economic, social, political, and natural environment.The condition for the survival and development of an organization is the ability to learn and adapt to the anticipated internal and external changes determining the operating conditions.Cities can be analyzed and described using the concepts of Sustainable City, Smart City, and Resilient City. The main objective of this paper is to develop and present the "Fundamental Power of the City" index – a tool for strategic diagnosis and monitoring of city development, where the fundamental power of the city is a synthesis of the concept of a sustainable, intelligent, and resilient city. Research methods include literature analysis and synthesis, and design method.
