Things like company culture and focus on either shipping products fast to get as much cash as quickly as possible vs building quality products definitely comes from the top management. But this support needs to be something more than empty phrases in come corporate emails. Same principles as say in software development.

If middle managers and top engineers see that there is no reward in doing things right and taking time, in fact its shooting one's foot, then most folks +-align with this policy and move on. At the end almost everybody is in for the paycheck.
