@chai2,
I am from three work worlds (and I suppose people think from outer space sometimes too). Anyway, I worked as a lab tech/researcher for 15 years, in landscape architecture for twenty five, and had two art galleries and was involved some in the art world during all that time. So, man, have I been exposed to jargon?
Actually, not that much, since I never worked what you would call corporate, though one firm was a small one (seven people including the boss).
When I did run into jargon - I remember specifically a short set of classes we had on communication skills for designers - I wanted to throttle the teacher with, oh, let's say a dead eel.
Our landarch contracts were always in plain words, while we had legal rep on the text. Conversations with clients, always regular words.
