The global competition and increasing quality standards to a modern car as well as shortening of product development cycles enforce the validation of manufacturing process at an early stage. Furthermore, the influence on products from the sight of manufacturing is necessitated. Close coordination at the interface between component development and production planning is the basis for early validation of product design. Thereby, it is possible to avoid cost inktensive modification efforts after conclusion of product design. For this purpose a paradigm change from discipline orientated operation to an integrated approach is essential. Through virtual validation of producibility along the entire process chain (press plant - body construction - paint shop) and cross-process result transfer recording of production orientated product properties and their consideration in product development should be facilitated. The challenge of this project is to link product development and manufacturing technology to a continuous, digitalized and cooperative planning of development and production. To achieve this aim two strategies of resolution are pursued. It is intended to integrate all data which is generated by CAD systems and simulation tools, etc. into a PDM system. This allows for a consistent storage, administration and supply of data that is generated during the product life cycle. Additional development of fast and flexible direct interfaces is purposed to connect all simulation tools involved in the manufacturing chain. The present paper shows that simulation data exchange across the entire process chain pose a challenge because of different data formats, varying mesh definitions and lack of interface standardisation. Until now blank thickness and plastic strain were mapped within the process chain with the SCAIMapper receiving an adequate mapping quality for parts. Nevertheless discrepancies due to geometry differences and interpolation inaccuracies occur. Remaining work is the mapping of stresses and entrainment of discrepancies to reference geometry that should be included into the process chain. Moreover, it will be possible to query the production planning status at any time in a module cockpit using maturity indicators, thus achieving the highest possible levels of transparency for all those involved.
