Deciding what's practical is the hard part in light of diminishing returns.
The first million dollars reduces risk a lot. The next million much less reduction. The next million even less reduction.
How do you decide when it's not worth spending another million?
If an engineer said they could spend 5 million and delay the aircraft another year to mitigate a risk that was thought would never occur, would you as a manager say do it?
How about spending $100k to hurricane proof a house. On the gulf coast sure. 100 miles north, maybe.
But 300 miles north? Could be hit, but that's such a slim likelihood than no sane person would do it.
