If anybody thinks the difference between major brands is due a difference in factory processes they would be very wrong. The reality is every large manufacturer now has a culture built around Six Sigma/Lean/6S/Continuous Improvement/etc. Vehicles aren't manufactured in underground hideouts of secret societies. If a process if found to work well in one corner of the industry it absolutely permeates to other parts.

Here is video of a Mercedes C-lass production line moving as workers assemble by the way: https://youtu.be/z6c_Zs5DG0s?t=531

I agree that those methodologies have permeated the automotive industry. But does that mean that all automakers are utilizing them to the same degree of effectiveness? Anyone who's worked in a dysfunctional "agile" environment has experienced the danger of cargo-culting in methodologies that have proven effective elsewhere.
