I've found that I usually start with the "correct" way and end up regressing to the "wrong" way as more and more work piles up, stress builds and deadlines approach. I guess the "correct" way only works if the organization actually prioritizes it and gives reviewers the time to do it the "correct" way no matter what stage the project is in.
