@adrianco @jawnsy @GossiTheDog even EVP can't cut it if you're swimming upstream against a long established culture.
I've seen CEOs who've swapped out pretty much the entire exec team, and still been unable to make any headway against a 'deep state' praxis (usually centred around finance, HR and legal).
@cstross is right about corps being slow AIs (and people being the gut flora). You can change an awful lot and the stink's still the same.
