Hmm, if you do this for a living you work to a written and agreed specification. If the customer changes his mind or wants more (they always do) he has to write it down, agree the details with you and, of course, give you more money.

You can never guess in advance all the things that can go wrong, though after a few years you get a pretty good idea, and do things like checking input data even if you sent it yourself from the previous module. If you know your customer you can anticipate future changes and put comments in - "comment this bit back in for southern hemisphere".
