For example, an application company may work with a car dealership to design your personal computer system for them. The car dealer might not have much technical expertise but should be able to understand this diagram with just a bit of coaching. Therefore, the software developers may not know each of the details of having a car dealership.

The dealer can study the diagram and offer missing pieces without really understanding database concepts. It’s significantly better to iron out this sort of thing prior to actually creating the database or designing systems around it.
