Together with the county, its eight municipalities, the economic development agency Sankt Wendeler Land, the digital competence center, and the citizens, Fraunhofer IESE is developing an integrated Smart City strategy in the project “Smart Wendeler Land” that is intended to support this rural area by providing profitable digital solutions. The strategy focuses on four defined ecosystems: citizen services, general interest services, co-creation, and mobility. Within these ecosystems, individual measures and projects are proposed, tested, and realized. In conjunction with this strategy development, Fraunhofer IESE is realizing the conceptual design of a data platform that is to link the individual digital measures in the county in an inter-municipality manner. With the extensive support of the partner Zebralog, concepts for participation as well as communication processes are being developed. This will ensure successful development and implementation processes of the Smart City strategy in the county of St. Wendel with a focus on co-creation and citizen participation. The project partners aim to jointly develop the county in the sense of a public-welfare-oriented Smart Wendeler Land.
