This article presents 9 guidelines for building and leading UX teams. They are based on what I learned from the people who led me as well as my own experience: recruit diverse talent; set up a process (and iterate); involve other teams from the start; be fair; have regular ceremonies; pass on knowledge; have a vision; ask questions (a lot); and make UX visible.
Depending on who you ask, a design system and a design language might be the same thing or not. Regardless, the important point here is that both a system and a language go beyond a simple pattern library. They have to include a set of rules and guidelines to give the included components structure and meaning.
1) Data analytics is a lot like UX design. 2) Define the questions to be answered beforehand. 3) Data is meaningless without interpretation. Extensively collaborate with other departments.
