I know the plural of a anecdote is not data, but at a UK bank many years ago:-
. a testing authorised library was included in live env. . I called out "is anyone testing from 'xxx.testauth.load' ?" (I didn't know about live dependency, which was kept quiet) . nobody replied, so I compressed the PDS . WHUMP! I was told there was a fine for late payment (SWIFT, from memory) before live had IPL'd, and the fine was something like £1,000,000 ! Maybe they exaggerated, but it stuck in my mind as a kind of "measure twice, cut once".
