Enterprises increasingly demand IT support for the co- ordination of their engineering processes, which often con- sist of hundreds up to thousands of sub-processes. From a technical viewpoint, these sub-processes have to be concur- rently executed and synchronized considering numerous in- terdependencies. So far, this coordination has mainly been accomplished manually, which has resulted in errors and inconsistencies. In order to deal with this problem, we have to better understand the interdependencies between the sub- processes to be coordinated. In particular, we can benefit from the fact that sub-processes are often correlated to the assembly of a product (represented by a product data struc- ture). This information can be utilized for the modeling and execution of so-called data-driven process structures. In this paper, we present the COREPRO demonstrator that supports the data-driven modeling of these process struc- tures. The approach explicitly establishes a close linkage between product data structures and engineering processes.
