Supplier Quality Causes Problems for Audi?
Audi quality team found that the underlying cause was defective circuit boards from its only supplier of that part. When there was a problem with that part the supplier could not keep up with the demand for replacements. Because Audi did not have another supplier for that part, customers had long waits to have their car repaired. Audi sent a team of experts to work closely with the circuit board supplier and to improve quality processes. Audi reduced supply risk and a second circuit board supplier. Overall reliability increased and warranty costs went down.
