The systems design approach (better late than not at all) [automotive electronics]

The systems design approach (SDA), an emerging concept for the automotive industry, considers the total vehicle as one system vs. the result of a grouping of optimized components. The systems process begins with a complete definition of the system requirements, is followed by the examination of technologies, generation of alternatives, and selection of a design to satisfy those requirements, and concludes with the final development and prove out of the recommended alternative. The advantages of an SDA are illustrated through an explanation of six types of system designs. The SDA has inhibitors which result from the characteristics of the automotive industry and also drivers which promise a better-performing, more cost-effective product. Implementing the SDA will require new skills and will challenge not only product engineering but also manufacturing and the supply base. It forces a rethinking of traditional concepts of dealing with quality. It is concluded that the automotive industry must maintain some component thinking, but the time is appropriate for increased utilization of the SDA
