Principle of abstraction
The principle of abstraction is a grouping principle, whereby a hierarchy is adhered to with higher levels of abstraction placed near the top with more specific concepts underneath.
Example
For the teaching (not personnel) organization of a university the levels of abstraction would go something like this:
