There seems to be a strong focus on iterative process. Problems/needs are (actively) discovered and then boiled down to possible solutions/proposals or at least something that can be acted upon.

The focus on communication and discourse is paramount, because UX brings the user to the forefront and then has to convince owners and implementers. This kind of convincing is important and often challenging, because there are often tradeoffs involved.
