The essential properties of a product are defined at the beginning of the development process [1]. Consequently, dependencies of the product and the context must be considered at an early stage with regard to the effects on the impact areas of sustainability, such as climate change or social inequalities. In addition to the implementation of assessment methods, product requirements are derived from sustainability models [2].

Previous work has shown a heterogeneous problem picture with complexity-related causes in interdisciplinary cooperation [3]. Ambiguities can have a detrimental effect on the interaction of partial models used in product development. Differences in the semantics of models can result from the purpose of a model and can be represented, for example, by different levels of abstraction or depth of detail. These limitations in the interaction of the models lead to the need to continuously analyze dependencies between the requirements and their effects on the product context to avoid problem shifts within the effective areas of sustainability.

Therefore, the objective must be to support the analysis of problem shifts in the early phase of product development by optimizing the interaction of partial models at the interface to product development. With the help of the interdisciplinary approach of semantic interoperability [4], a systematic analysis of the interaction of partial models should be supported. In addition to technical aspects of standardization and the mapping of information models, research should also focus on human and organizational influences on interoperability.

Initial contributions address a context-sensitive extension of Model-based Systems Engineering to systematically support the inclusion of the continuously changing context of a product [5]. The use of knowledge graphs enables further analysis of the interactions of requirements as well as support for communication in the localization of information in interdisciplinary collaboration. Future work will build on this to address further questions of interdisciplinarity in the context of autonomous open source communities to explore practical knowledge, methods and ways of working in the transition of sustainability models in product development.
