Why Not Use Automotive Tools Meaningfully?

We all have heard of the automotive tools FMEA, Control Plan, Product Control Plan, MSA, PAPP, and SPC. But are these used in your company practical and profit-bringing? Be honest:
- Are the forms filled out only because they are needed for the initial sample to the customer?
- Are always the same FMEA and Control Plans used, stored and re-filed with the PPAP file?
- Does information from complaints flow into FMEA?

Sure it is going well in your company. If not, we could talk about how the tools can be used profitably.
