How do you build and run a PFMEA so it actually changes how parts are made?

Which quality KPIs would you set for this site, and how would you tie them to business goals?

What they are checking: Whether they connect quality measures to cost, delivery and customer satisfaction that leadership cares about.

How do you contribute to design for manufacturability before a new part is released?
