I am wondering if the printversion isn't already some kind of code book. I would need to check if the codes can be shown there.
I know the codebook feature from Globalpark (now QuestBack) and in theory it didn't look much different from a HTML page showing all questions, but of course with the relevant question and answer codes.
Usually in Market Research you prepare the questionnaire first in a Word version for example, so that you are able to discuss it with the client and the internal team and only once it is approved programming would start. In theory this word document could be the codebook. But often this version doesn't include the codes or not the correct ones, or during programming codes have been changed.
So for the ones analyzing, it is very important to know which answer actually has which code in the questionnaire.
But even if you have the codes nicely in the word version, imagine that during programming the programmer switched "YES" from code "1" to code "2" and suddenly the analysis fails misserably if it doesn't have this detail. I know that programmers shouldn't do stuff like this in the first place, but shit happens everywhere, so...
