Description / Abstract: Design for Six Sigma (DFSS)/Robust Engineering is the method GM is using to assure high quality in critical systems of our vehicles. The DFSS process flows the customer requirements to the design and then it assures that the design satisfies these requirements with minimum variation. Participation in, and support of, a DFSS project will be required by all suppliers of subsystems or components where GM product engineering is doing a GM DFSS project or where requested by GM. A supplier may be expected to conduct their own DFSS/Robust Engineering project to support meeting GM's performance requirements.
