Everyone knows, privately in their inner thoughts, that "biz-speak" is baloney.
They use that language as a front for insecurity, not knowing what to say, or not being willing to say what they really mean. If the PHB is obfuscating an unpalatable (and non-negotiable) demand in biz-speak, it's not like parroting back some biz-speak is going to change his mind or strong-arm him.
You chances are better if you address the actual issues in plain and sensible language (or perhaps don't say anything at all). Even if it doesn't work, it at least lays bare the insincerity of the PHB's biz-speak.
