Isn’t that exactly the problem, though? In my mind, these loan words from other languages create the illusion that they were clear and unambiguous. In reality, however, people still often enough talk cross purposes, but as they now use exotic language, they often won’t even notice. (And when they do, they start a flamewar about who has the right definition, which rarely leads anywhere useful.)

One other downside is that all that made-up wording makes it unnecessarily difficult for job starters to find their bearings.

If you organise your team’s tasks with post-its on a whiteboard, why not just call that “task board”, plain and simple? That might not imply all the particularities of the process, but there are many examples from all areas of life where terms in themselves don’t convey perfectly comprehensive meaning, and yet, people manage to deal with that.
