ProverbPerseveranceGerman origin

Never change a running system

Meaning: Functional systems risk dysfunction when modified without pressing necessity.

Origin: A pseudo-English saying from German computing, where it is also heard as "never touch a running system"; it is rarely used in English-speaking countries. It adapts the sports maxim "never change a winning team" — English speakers would say "if it ain't broke, don't fix it."
