Ized is not wrong. But i think Ized tended to lump everything together without seeing the variance in manufacturing methods.
CNC is the main way bodies are manufactured, and that is already a given. The hand made part is where your craftsman actually put them together and put in the finer details. The wood selection is another point where you cannot get a machine to select for you. That is done by human judgement.
Go check out their manufacturing methods, same for PRS and compare them to the factory assembly methods of say cheaper export lines or makes for instance.
The main difference and what I would called "made by human hands" is the way they shape and put it together.
There is no real template and that explains your variance also which some here contribute to as poor built quality.
