Stress to your bosses that if a person can't read AND understand the script that they have no place fiddling with it. Quite simply, if you can't deal with the code direct, and need to hide behind a GUI, you have no real hope of handling it when things go wrong. More to the point, you will greatly increase the odds of something going wrong.

This applies to any kind of scripting or programming and Kix scripts are (relatively speaking) very elementary, even if sometimes things don't quite work as they're supposed to. There are only a rather small number of commands and functions. The power comes from putting them together the right way and of course that only comes with proper understanding. The key word here is understanding.
