The current automotive market introduces year in and year out an increasing number of model variants tailored to customer needs. Beside an increasing number of vehicle body types, the technological level is steep rising. Technologically highly affected areas are drive train, chassis and electronic assistance systems. The target of development departments is to fulfill new technological requirements with the best possible quality and suitable technical solutions meeting customer expectations. The more products are customized the more flexibility in developing and producing these systems is necessary. Contrariwise the R&D capacities increase only slowly or are limited due to different reasons. That is why efficient methods to deal with the high amount of vehicle types and technologies have to be implemented. The state of the art in developing vehicles today is characterized by keywords like lean product development, modularization, platform strategies, supplier integration, etc. The question is if current development processes will be able to deal with the high complexity arising out of the number of variants and the dependencies between modules, platforms and subsystems? Which process factors are crucial for development departments to engineer products suitable to industrie 4.0 production possibilities? Interestingly the production concept industrie 4.0 could provide some potential answers. Industrie 4.0 encompasses methods for flexible, efficient production systems in extreme down to lot size one. This will be enabled e.g. by to the use of self-organizing cyber-physical systems, cluster intelligence and the availability to utilize other for production flexibility relevant data. Cyber-physical systems are characterized by the autonomous acquisition of data, networked machine to machine communication and machine learning. Currently development processes can´t offer cars engineered as one individual item. But the production possibilities of industrie 4.0 especially the manufacturing of lot size one - would as a consequence necessitate to have an idea about a development process which could develop one specific product for one customer as well. This new high flexible development process will be called in this master thesis "development 4.0". The aim of this thesis is to analyze today`s vehicle development process structures and to identify critical process factors, having in mind the highest possible flexibility regarding product features. Furthermore it shall be checked if industrie 4.0 methods could be used in development to expand the possible range of complexity by using given capacities and minimizing development cost for vehicle variants in parallel. The development processes of lean product development will then be advanced to development 4.0.
