been working on dime for 43 years and 13 of those c.e.o. so 43 years ahead of a long time to work anywhere 13 years of the c.e.o. of an organization as big as diameter is extremely demanding job so it's natural that you would leave after that stage however the other factors at play here is approaching a massive transformation as all major car makers are at the moment for several reasons the switch track from ability autonomous driving etc it's also going through a major restructuring process so it makes sense that you would change leader at this point get a new person in new ideas and to lead this period of transformation also restructuring and also one of the point it's important what he is leaving a c.e.o. but he's not only believe in diameter so when this was announced last year the announcement was framed in the context that he was leaving in may 2019 because the plan would be that in 2 years 2021 he would return as chairman of the supervisory board so in 2 years time he would actually be back in time or in a different capacity but he's not fully leaving so that's important remember so
