In BMW's high performance luxury vehicles, about 80 electronic control units are networked together to provide the driver with numerous features, e.g. dynamically controlled safety applications, passenger comfort, information and entertainment, etc. To guarantee an appropriate level of quality within the allowed integration time of such features, new and progressive techniques are needed to support the early phases of development with maximum potential to solve methodology issues of the future development. In addition to new programming notations reliably controlled integration processes for components with significantly different life-cycles including information management and change control are sketched. For these purposes BMW chose to utilise the Unified Modelling Language (UML) and to define its automotive-specific subset of UML. The structural part of the analysis model is specified by a state based specification notation to generate 'executable requirements'. To support our methodology, domain specific and commercial tools have been tightly integrated to support a seamless development process. Effective information management and change control are based on a sound and seamless management of the projects' requirements. Thus, the information model of the developed products is embedded in the requirements model.
