Digital twins can offer various added values for companies. As part of a three-year research project, we are investigating the methodological approach, for building digital twins in existing infrastructures. In particular, the functional requirements of future users will be addressed, as this is less focused in existing approaches. Within the framework of this publication, we discuss the applied methodology as well as the created models and concepts. Initial insights were gained in the simultaneous development of digital twins in parallel projects with use cases for electric motors, production process monitoring and maintenance of gas turbine components.
In detail, it becomes clear that software development methods (e.g. use cases, user stories, scenario development) are a good way to describe the expected added value functions. It is essential to involve the future users in the development as early as possible. Transferring the necessary functions identified in this way into a functional architecture shows that this architecture is mostly independent of the use case. Likewise, the IT systems used here hardly vary at all. Overall, it shows that a methodical approach can be followed in the development and the implementation can have a high degree of similarity, even in very different use cases, while the exact design, depending on these use cases, is very diverse.

Looking at digital twins in terms of their information sets (master and shadow models), a significant part of the shadow models is created in the context of product life. Digital twins must be designed accordingly, focusing on their dedicated added value or business model. This concerns not only the information and data models, but also the communication technologies, processing routes and interaction mechanisms used. With appropriately designed digital twins, product life becomes a source of knowledge for optimizing or tracking product systems. MRO processes play a special role in this. Here, the digital twin becomes a monitoring system, information source, process manager or information sink through suitable functions and thus a potential knowledge repository.
