Some people jump early. I’ve stayed long enough - or returned later on request after doing a startup - to see whole orgs and product lines in telcos (!!), banks (!!!) and even government agencies (yeah, wasn’t really expecting that tbh) getting structurally better over time due to concerted effort of a relatively small group of folks.

I’ve been part of turnarounds where senior execs have said that the three hundred people here will lose their job if nothing changes. I still talk to some of those teams that transformed themselves and others, and made it.
