Cities are getting bigger and more crowded. This leads to an overuse of water-/ energy- resources and infrastructure, which are partly irreversible. In order to be a worth living place in the future, parts of a city have to change, e.g. housing, mobility, and supply of urban life, in harmony with nature and environment. For these changes a city, a so-called Smart City, needs a strategy. This paper will examine whether the St. Gallen Management Model (SGMM) can be a basis for the Smart City strategy process. For this purpose, the three sectors of the SGMM are analyzed in more detail and applied to the context of a Smart City, focusing on the power ranges Smart Mobility and Smart Environment. The analysis demonstrates that the transferability of the SGMM to the research application Smart City is well given, especially in the aspects stakeholders and environmental spheres of the sector environment and in the aspects frames of reference of the sector organization.
