UX Modeling - The Other End of the Process, Right?

Modeling is one of the most important faces in design, but it's often not acknowledged. When you go on social networks and see discussions about UX design, most of what people are talking about seems to be about the user interface level. So I'm really happy with the teams that we're working with that are kind of starting from scratch and trying to build this end-to-end system. Like to see how the entire forest is laid out before they start looking at the trees.
