If we're talking about a big multinational corporation, is the CEO the head honcho? In a company big enough to warrant having a COO and CEO, is the COO effectively second-in-command, or is more of a board-thing?
Also, how does corporate presidency and vice-presidency work, typically?
U.S. or Japanese business models are fine for this. Basically, I'm just wondering what the job title would be for someone who was "Number Two" in a big company.
