And let's not forget that the last time a German company tried to do a major project for GO, this is exactly what happened. And so they were unceremoniously kicked to the curb after 18 months.And I would be disappointed if they were to walk in, act as if they know everything, and just start doing things their way because it's DB.
Hopefully their involvement will be thoughtful, informed, and open minded.
Sure, there are plenty of current practices and mindsets that need to be challenged or set aside, but not "just because".
I'm hoping that their institutional memory is good enough to remember that.
