Certainly some software looks routine and feels repetitious while you are doing it. But very little if any software is amenable to determining its manufacturing tolerances. That phrase is jarring because the idea of manufacturing tolerances for software does not make sense. But manufacturing tolerances are fundamental to statistical process control, which then builds on statistically valid sampling to determine if part of a process is failing. (Or it can determine that a quality issue is something other than a process failure.) But it depends on setting and using manufacturing tolerances wisely.
