Whatever applies to engineering applies to the business end of tech as well - I've enjoyed considerable longevity in sales (management) by staying humble initially but displaying very forceful convictions once I've figured out the lay of the land upon joining new roles.
It really pays off to listen and stay open minded before you start enforcing best practices you've picked up from previous experience and assignments.
Give yourself the opportunity to actually feel like an impostor deliberately (if only for a brief period of time)! Really dig into the reasons why things are run a certain way before you propose changes: this will set you up for success and will attract a lot of goodwill.
I know this sounds trivial, but humility is an extremely underrated trait in tech, especially if paired with experience and the power to pull off change for the better.
