But it goes wrong very often actually (meaning the outcome is non repeatable). Most of the time you don’t find out, but if there’s two or more people doing the exactly same process (application for getting something out of say a government institution). You just need the forms to end up with different clerks to get two different outcomes.

This is why in Germany the common wisdom is for say claiming disability, you will always have to reject the first ruling, no matter what. You will get a better result the second run through (maybe even reject that, too).

Imho it’s the curse of complexity. But there is little incentive for bureaucratic institutions to „refactor“ their processes, as it would mean less headcount.
