I agree with the part about the number of people being managed, however usually there's a huge difference in management structure. For instance we have some standard big corp and its tech department. So you'd have a developer,senior developer,tech lead, some sort of team manager.Then the team manager would be reporting to the person that runs the particular division or department. The head of the department would report to some VP who would eventually report to the CTO. In a small company that'd be like developer=> CTO. That "Chief",in which case it loses the purpose.
