摘要

One of the most urgent challenges in automobile development is the reduction of quality problems and the significant costs associated with them. A look at the official recall statistics shows a clear increase in the last decade (Figure 1) [1], [2]. An increasing portion of the recalls is due to problems in the electronics and software area. ADAC (the German automobile club) reports that one-third of all automobile breakdowns are due to problems with electronics [3]. On the other hand, increasing demands for comfort and reliability and the desire for less environmental impact in turn cause constant increases in the complexity of software-intensive mechatronic and electronic systems in automobiles. The development of these systems is accompanied by consistently increasing demands for speed, reliability, and efficiency. The sustainable resolution of these conflicting goals necessarily requires a networked and well-structured cooperation among all participants in the production process; that is a secure mastery of automotive systems engineering [4]. For a systematic implementation of automotive systems engineering, it is necessary to select an appropriate maturity model that can serve as a guideline. Considering the example of the development of systems for electrical energy management in automobiles, this article will present and discuss experiences gained during the accomplishment of a process improvement project for systems engineering based on the Capability Maturity Model (CMM) [5] [6].
