Work experience:

I'm an IT person but not a computer scientist. Maybe you don't see us other IT people as being "one of us" but if so, then the question needs an IT option.

I don't see a pattern behind the work experience question. This might be something that happened if the goal with this question changed between surveys but you wanted to keep the same options for the sake of being able to compare the two surveys. So, I won't suggest refocusing it to follow a clarified pattern but maybe a few other general categories (like "Other IT" for instance) can be added if there were enough responses from the last survey to justify it.
