    Using expertise and combining functionalities from different domains has led to a significant increase of information engineers have to deal with. It is hardly possible to identify influenced components in activities like change requests. A model containing tracelinks between the elements of involved partial models as an essential part of PLM based Systems Engineering helps to overcome this deficit. The main obstacle for a broad introduction of traceability is the significant workload involved in creating tracelink models as every element combination has to be examined for dependencies. This calls for an approach to support developers in creating tracelink models more efficiently. The presented approach Eco Tracing allows developers to significantly Economize modelling effort. In order to do so, the method uses the hierarchical structure of many models and a top-down analyzing approach to exclude element combinations prior user examination. Furthermore Eco Tracing allows choosing the desired level of detail flexibly while modelling. Eco Tracing is a promising approach helping to establish traceability in product development by reducing modelling effort significantly.

    Mechatronical products integrate components that are developed by different fields of engineering and combine them in order to provide new functionalities. The main challenge is the ever increasing complexity and the required degree of interdisciplinarity. The joint research project MIKADO adressed this demand by integrating domain specific development methods and tools into a more systems-engineering-oriented approach. Special emphasis has been placed on the early phases of product development in order to facilitate an early coordination between mechanical, electronical and software engineers and to provide them with easy means for the functional verification of virtual product models. The MIKADO cooperation platform will improve and accelerate the planning and execution of mechatronical product development projects. Interfaces for connecting commercial engineering tools to the cooperation platform guarantee the industrial applicability of the MIKADO solution in connection with existing system landscapes. This reduces investment costs and makes the MIKADO solution attractive, especially to SMEs. The enhancements of the FOD modeler help to collect and manage all requirements of a mechatronical product as well as to define and depict their connections. Their continuous connection to functions, parts and CAD models allows for cross-checking the fulfillment of several geometric requirements. Specific tests for functional and geometric analysis complete the Functional mock-up. They are started from and their results are managed directly in the FOD modeler as well as on the cooperation platform and thus make a continuous review of the products' degree of maturity possible. The methodology for combining a comprehensive requirements management with a functional mock-up for the verification of requirements will be the basis for further research. In addition, the results of MIKADO are planned to be used for commercial products, which will be sold by the project partners.
