Due to the increasing smartization of products and the ecosystems in which they are typically embedded, holistic considerations of future value-added systems are becoming increasingly important. This also determines fundamentally new challenges for the engineering of the future's smart Products. In order to be able to address the increasingly fuzzy system boundaries associated with this, this contribution introduces a System of Systems Engineering Lifecycle Concept considering smart products and services as core components of connected System of Systems ecosystems. Main characteristics of smart products and system of systems are discussed and in a real existing scenario of a sustainable landfill the presented System of Systems Engineering Lifecycle Concept is used as a System of Systems Framework for the given Use-Case.
