In my company (similar size with Boeing, also manufacturing but in a different business sector) we mostly promote from within, but the CEO is always a marketing or sales guy and IT is reporting into the CFO, which has absolutely no knowledge about the area. Only the plant managers are former engineers promoted up, everyone above that level is former sales or marketing.
