Found it very interesting to note that Business Analysts have been left out of the survey. BA's have traditionally been included in the IT Department or IT Professionals category.
However, there seems to be a shift in industry (and rightly so, just happened at my job too) that is moving the BA role out of IT and into either an independent function within business, or as a part of the Enterprise Architecture function (which should be independent of IT as well). While there is still quite a difference between BA and EA, the two areas do complement one another very well and should be working together.
Still, strange to not see BA salary stats in an IT survey because a lot of companies still have their BAs as part of IT.
Edit: If you go through the detailed results there were a number of BA respondents listed under specific technology platforms, but they don't appear on the job title list that is independent of a technology (just average salary). Still, 9 respondents in total (of which 4 could be duplicates) isn't a very large dataset to work off.. Overall the respondent numbers are pretty small. It was not a very large survey by any measure.
