I really hate classification systems like that -- who's to decide what's major, minor, critical, etc?

The NASA one's much more clear -- (A) : failure is likely to cause the loss of human life; (B) : failure is likely to cause the loss of a spacecraft or failure of the mission; (C) : failure is likely to cause the loss of a secondary mission objective; ... and everything after that's just an annoyance of some sort.

Years ago, I wrote a trouble ticket system, and we had those sorts of terms, but I qualified then all ... it went from 'cosmetic issue' to 'the building is on fire', with steps in between for 'annoyance', 'can't get work done', 'multiple people can't get work done', 'the boss can't get work done', etc.
