Interesting to compare this with practices in other professions, eg Doctors, Architects, Scientists and so forth. Certainly management happens in those areas, but I believe that as your career progresses you would naturally be expected to take on more management activities - there isn't a dual track in quite the same way. In more recent times the waters appear to have become muddied somewhat, with the appearance (and glorification) of administrators, project managers, 'CEOs' of various kinds.
