From the perspective of the entire Transformation domain,
Architecture is performed more at the top of the stack and less at the bottom.
Conversely Engineering is performed more at the bottom of the stack and less at
The further down the stack we go the more concrete things
become, and the further up the stack we go, the more abstract things become.
This does not mean we are saying that there is no Engineering happening at the
top and there is no Architecture happening at the bottom.
