I disagree. It actually needs less regulation.
The siloing of knowledge and duties is why it was always somebody else's problem. So you simply take out all the regulations that obligate siloing and replace all of that kerfufle with a single rule: "If it's on your plate and nobody else has published that they've done the work so far, it's your responsibility, silos be damned, and failure leaves you liable".
That's it.
That's all we need. A removal of siloed thinking and a duty to complete all of the scheduled work regardless of whose toes it tramples.
That would have solved the problem. But, because departments never like to give up powers they obtain, a side-effect would be that departments would be proactive. They wouldn't walk down piers, looking for strange things. Rather, if they heard of strange things that are their department, if they don't want to be shamed, then they need to ask the company for more information. Because then it's on their plate and not that of a rival department.
The other benefit of using this approach is that it isn't about the special cases, it's about the general problem that underlies all of the special cases of this sort: nobody takes responsibility until it's already a disaster.
If a department is liable for pretending the problems aren't there, then the department wil CYA. If the only way to do so is to do all the outstanding work, regardless of title, then that work will get done. If the only way to get it done right IS to give it to the right department, and they're on the hook until that has happened, you're damned right it'll happen.
I've worked in the public sector, I've seen the paranoia and closed-mindedness first-hand. That's not going to go away. So you solve the issue by exploiting those traits, since you can't eliminate them.
