I have learned a lot of this business terminology not from being a corporate wage slave (which I am), but from doing outside contract work. I think its a good idea for consultants learn these buzz words, since often enough they are dealing with business people as clients. I believe that corporate-slang word "deliverables" is really a legal term found in most independent contracts. Otherwise suck it down and tell them you have "domain specific" knowledge and the ability to "add value", and the man will pay you.
