This tip might sound strange in context with building blocks - but sometimes it’s easy or helpful to explain the fundamental or crosscutting concepts (other terms are principles, styles, stereotypes or patterns) instead of all the building blocks.
For example, if you build a microservice-based system or constructed system as a pipe-and-filter architecture, the explanation of the fundamental principles might be more useful than the elaborate discussion of single building blocks.
But: You should have a Level-1 building block view
Please keep in mind tip 5-3 (level-1 is your friend)
