Perhaps the analog/digital distinction is relevant here. If you are making yogurt, and you slightly deviate from the ideal recipe (leave the culture growing for too long?), you will probably get yogurt that tastes a little off. If you are writing code, and you deviate slightly from the ideal program, you will probably get junk: compiler errors, massive performance hits, blatantly wrong GUIs....
