Agree with all the responses to my top level comment, in that management is ultimately responsible for setting and maintaining the engineering culture. It can be tough, however, to balance competing (tensioned) requirements - if you have to choose between engineers that follow best practices (user stories, standups, TDD, pairing, etc) and no engineers at all (let's face it, they are scarce today) - what do you do? Wait to hire engineers and let the product deadline slip even further? It's a tough balancing act.
