Working for german medium-sized companies:

It's really that the upper management does not appreciate change over departments if it's not their idea.

There is always the mentality that "why fix it if it works" where you actually have to wait for people to go to their pension to really grab a process and drive change.

You then get partially digitalized processes where digital native departments are concerned but they always have to solve the problem of interacting with a bunch of legacy systems and workflows, which in itself is so much harder and more inefficient.

Whats funny is when its privatized by publicly traded companies it becomes this weird nationalized-kinda but not really thing that turns the economy into a bifercated class of first class citizens and second class citizens.
