#garbageingarbageout

There are two very different kinds of objects in my life: those I drop and say 'oh, shit!' and know I have to pick up immediately ('better stop and see where that went, see that it's ok', 'gonna need that for later') and the 'ehh… whatever. look for it later…maybe. it can't have gone far. I'm sure it's fine, I'll do something about it later if I really have to' kind.

Last week I was walking a dog, and passing the entrance of the park I saw two young parents enter, walking their child. The young man in a black hoodie with the hood up in summer and hip-hop style lettering across the shoulders threw his empty can in the grass. His attract young partner looked at me, looked around, saw me again, kept walking, looked around, then threw hers, too. Their child, slightly ahead of them, didn't see either moment, but I suspect there will be an influence on their behavior one way or another by the time she's their age.

Garbage in garbage out is a term commonly used to state wrong input produces wrong output in the industry.

IS THIS CORRECT...?

Actually garbage in garbage out is a term supposed to be used to state that THERE IS NO PROCESS, not to state wrong input will give wrong output.

If there is a process, wrong input will not go in, it will be identified at the entry point or filtered or not accepted by the process, since processes will have validation, verification, rules, policies, work instructions etc.

The input is transformed into an output through the process. So either garbage cannot go in or if its accepted it cannot come out as the same (same garbage), it should come out as something else (may be refined garbage or some different output, getting the same garbage as input is only possible if the process is missing or it has not done a transformation).
