A simulation model for studying strategic SPI in the automotive industry

This paper presents the approach, results and conclusions of a simulation modelling activity conducted by Fraunhofer IESE in collaboration with DaimlerChrysler Research and Technology. The purpose of this activity was to support DaimlerChrysler Research and Technology in performing a study that aimed at exploring the level of process leadership (PL) in (embedded) software development achieved by one of DaimlerChrysler's car divisions within the next five years. A key issue of this study was the identification and determination of influence factors and measures expected to have an impact on the level of PL. In order to focus discussion and provide a quantitative basis for analysis, Fraunhofer IESE and DaimlerChrysler Research and Technology jointly developed a simulation model following the System Dynamics approach. The structure of the model and its calibration was based on input received from DaimlerChrysler Research and Technology and experts from the car division. In a first assessment, the model was found to be useful for running experiments that qualitatively reflect the fundamental dynamics of the factors influencing PL. To improve the predictive capability of the model, additional data has to be collected and integrated into the model. In addition to its specific value for DaimlerChrysler, the simulation model may serve as a framework for exploring SPI strategies in other companies.
