Yup. Did it while working for a fuel-injector company about a dozen years ago.
The cynical perspective of time renders this conclusion: PFMEA & DFMEA worksheets, methodologies, and procedures were not "automatic" but provided the impetus for creative thought. Such as in "Say, here's a failure mode...I wonder if we could get THAT feature changed by the design guys?" Then I'd take the personal initiative to go as a committee of Quality + Manufacturing + Production engineers and go to Design Engineering, explain our case from the Manufacturing point of view, and try to get them to change the design. Sometimes yes, sometimes no. Management rarely if ever cared if the xFMEA process actually worked, just that we had the paperwork on file to show the customer Supplier Quality Engineers.
