The fragmentation of the automobile market continues unabated. Automobile manufacturers try to generate niches of demand between established automobile segments by designing ever new carriage concepts. The consequences for the development process are that complexity will continue to increase in the future. The vehicle safety department of the Audi AG carried out a structural analysis of different subsystems of frontal and lateral safety and acquired the basis for efficient management of complexity in cooperation with Teseon GmbH. Teseon provides consultancy for the application of methods and tool support for complexity management. A principal project goal thereby was to establish transparency and system understanding in a multi-domain complexity, which serves for reaching short response rates in tight development times. A multi-stage procedure was carried out for the analysis of a frontal protective system with the perspective focused on OOP ('out of position') as well as for the analysis of a lateral protective system with a focus on the understanding of the entire system. The data collection and analysis processes were supervised by Teseon experts and carried out using the complexity management software Loomeo. On the basis of the structure analyses carried out various methods for controlling the existing system complexity could be deployed and established: Analysis of impact; Trace-back analysis; 'Set-screw' analysis. Besides the methods of controlling complexity - here the main starting point is transparency - the next step consists of successively designing the product structures to be more robust in order to reduce the impact of modifications in general. Various structure attributes (clusters, circular paths, hierarchies, etc) can be considered to this end. The work carried out leads to a considerably sharpened understanding of the system. Previously apparently unknown connections become visible and therefore controllable and relations between elements of subsystems get transparent. Measures for adaptation become more efficiently manageable. This finally leads to increased reliability in the development processes while saving on resources.
