in thread Perl in space?

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.

    I don't like the classification systemas too much myself but they do serve a purpose. E.g. in a selection process to make a decision or to justify an expensive code inspection etc. In defense of it I can say I provided a summary, of course everything is specified in detail;) For example "catastrophic" is described as:

    • Loss of life, life‐threatening or permanently disabling injury or occupational illness
    • Loss of an interfacing manned flight system
    • Severe detrimental environmental effects
    • Loss of launch site facilities
    • Loss of system
    So I think both standards are equally (un)clear;)
