Well I've seen culture change in a day. If you have enough power and can unilaterally change an incentive structure you can get people to fall in line really quickly.
When I worked at a bank we had pretty predatory selling practices and a fitting culture. This was starting to catch the eye of the media and government so the Bank exec stepped in and said the parties over and If anyone doesn't conform to these new rules then they're out on the street. That day, the culture changed, and everyone was happy to changed because they didn't want the existential consequences to happen to them.
There's the softly softly approach over years and then there's the speeding u-turn. Both can work. The latter just takes more grit.
