Garbage in garbage out is this term rightly interpreted? (Process.. part2)
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).
Therefore, using garbage in garbage out to state, wrong input will produce wrong output is completely incorrect. It is a term meant to be used to state that THERE IS NO PROCESS …!
