Incentives do matters. It should be pretty clear to anyone on this forum. The parent is absolutely right. Responsibilities do matter. In this case, there was clearly a systemic problem that was repeateadly ignored by mulitple levels of hierarchy.

You position is a position of principle. When peopke lives are at risk (boeing, fukushima and yes even the post-office) pragmatism must prevail. Those in charge must pay the price, otherwise you incentivise financial results over everything else. People die? Oh that's because Greg in engineering is an idiot, burn him!

The problem is with insufficient QA and processes in place. If a coder delivers code that is insufficiently tested before deployment, the onus is on the product owner. It's the reason "owner" is synonymous with "person who is responsible."
