The paper discusses increasing demands on product architecture and the resulting requirements and implications for organizational structure. Due to the rising conditions, the product architecture is increasingly developing into a complex construct in which transparency must be increased to continue developing products effectively. The approach of this paper is, based on the method of Design for Variety, a matrix-based modularization with the DSM and its extension to a cross-discipline multi-domain matrix to establish a reference to the organizational structure and to align it in a value-added way to good product architecture. This is done by an exemplary Investigation of the product family generation of a vacuum robot.
