This role has been around in IT for a long time. I know this for a fact - it's been my career path. At various times I've been titled business analyst, liaison, internal business consultant, business technology specialist - the list goes on. At it's heart, this role requires that you really understand and appreciate the business side - and they work to find the appropriate technology and use of that technology. It's for people who aren't quite as hard-core techy but also aren't end-users. It takes a high tolerance for "fuzzy" and a real interest in learning the business side. Personally, I love it.
