That gets actively dangerous; a lot of more recent safety mishaps are more of the variety of "processes were followed, but things went hilariously off the rails and no one noticed and spoke up".
Culture and expertise matter just as much if not more, especially today now that we all (in theory) should understand source control, testing, safer languages, etc.
I think Admiral Rickover's methods apply just as much today, and applying that kind of thinking would fill major gaps in a lot of organizations - he emphasized good communication, a sense of responsibility, and thinking on your feet, and his safety record is unmatched.
I think aviation also approaches process a bit better - by having much of it be more informal, less rigid checklists, it doesn't encourage people to suspend judgement so much.
There's also the Tankship Tromedy, which really emphasizes the engineering legwork of just chasing down, understanding and fixing every last failure mode you can find.
