There ARE formal definitions of positions, title/rank, and requirements for experience and education, (as well as pay range) defined by the US Federal Government's Office of Personnel Management. These are used for determining staffing requirements in government contracting and hiring. Most mature government contracting companies follow these standards. In private industry, though - it's like Lord of the Flies. As far as I've seen.
