How do I sign up to volunteer as one of these sacrificial lamb CEOs? Because I'd absolutely love to fail at something and then get paid a bunch of money to look bad for a few months before people forget and I can retire into the sunset.
First step: get a title where it wouldn't embarrass the board to put you in the CEO position. This could be founder of a hot startup, or an executive at a competitor, or CEO of a smaller company.
Getting there is left as an exercise for the reader.
