I don't mean to claim that Renault is technically incompetent (obv. that's false).

I find that these companies have something very unique about themselves in terms of culture. And you lose a lot when you try to change it.

For eg. a lot of expats in Tokyo have this attitude that Japanese companies are dim-wits and that they have "westernize" and become English-speaking techbros (Rakuten calls this English-nization).

There might be some things that can be emulated better, but the solution always tends to be a bit too... christian, or rather monotheistic (ie . wipe out everything before and mass replace).
