Is there an italian way for DevOps?

probably not ...Consider a step by step approach

It’s not all white or black,explore the nuances of grey.

Cope with cultural resistance,be perseverant.

There is much to learn also from “old dogs”

Earn respect with facts

Adapt to contingency

... but let me throw in few personal hints:
