This workshop refers to the case of the faulty GM ignition switch, which, after several severe accidents,
had led GM to launch one of the most infamous recalls of automotive history in the first half of 2014.
In total, the recall covered more than 30 million vehicles and resulted in a $900 million deferred prosecution agreement.
As the corresponding investigation by the federal authorities also included the disclosure of numerous documents,
the case offers a unique possibility for the DTU Robust Workhop series. Provided with physical samples of the Ignition Switch
and based on an introduction to Robust Design, the participants are challenged to analyse the switch’s functionality,
to evaluate its robustness, as well as to reason about potential limitations of today’s production-focused quality practices
The workbook is the central document of the workshop.
The workbook summarizes all information relevant for the
exercises and is published OPEN SOURCE.
