Aha. To some extent I think it's a hiring and/or organisational values thing. You need the right people to congratulate each other on the right types of work for it to be a long-term sustained thing.

There are also some more formalised versions of the scientific process applied to the workplace. Mike Rother's Improvement Kata come to mind.

Edit: also get good at negotiation! People are complicated and refuse help even when they obviously need it. Being a good negotiator ideally helps everyone.

Second edit: another thing is leading by example. That's been very powerful in my experience.
