“I start with the principle that when I'm in Japan, I'm making decisions for Nissan,” says Ghosn, the CEO of Nissan and Renault. “When I'm in Paris, I'm making decisions for Renault. And when I am in Russia, I'm making decisions, eventually, for AvtoVAZ. I don't mix the different responsibilities because I just want to make sure the different teams in charge feel responsible and there is no confusion between the different companies. So, a lot of pragmatism, some basic rules, professional people around you and, at the end of the day, it's possible."
