Abstract. Lifecycle management enables enterprises to manage their products, services and product-service bundles. IoT and CPS have made products and services smarter by closing the loop of data across different phases of lifecycle. Similarly, CPS and IoT empower cities with real-time data streams from heterogeneous objects. Yet, cities are smarter and more powerful when relevant data can be exchanged between different systems across different domains. From engineering perspective, smart city can be seen as a System of Systems composed of interrelated/ interdependent smart systems and objects. To better integrate people, processes, and systems in the smart city ecosystem, this paper discusses the use of Lifecycle Management in the smart city context. Considering the differences between ordinary and smart service systems, this paper seeks better understanding of lifecycle aspects in the smart city context. For better understanding, some of the discussed lifecycle aspects are demonstrated in a smart parking use-case.

IoT-enabled smart city service systems are well recognized to address issues of urbanization in the city environment. In most cases, those systems are vertically locked; and from lifecycle perspective, independently designed, built and operated. Therefore, there is a need for a global vision to horizontally integrate those systems to ensure smooth flow of information across different domains. To ensure interoperability and better management across different phases of smart city lifecycle, this paper highlights the need for smooth exchange of two types of data/ information: (i) generated data from IoT data sources; (ii) lifecycle system related information. This paper proposes the use of The Open Group IoT standards to ensure interoperability and smooth data exchange; and the use of lifecycle management system to create Bill of Materials; export Objects' Tree and exchange lifecycle system related information. It also demonstrates the interaction between the proposed lifecycle system and IoT platform within smart parking use-case.
