You need at least some UX representation on the team to be effective. The challenge is that it’s hard to have all the skills REQUIRED on such a small team. I’d recommend having a dedicated UX lead on each team that has the skills most likely to be needed, as well as some SUPPORTING UX STAFF that can help out. One researcher might be able to cover multiple teams in many cases. As to what TYPES of UX skills are necessary, it really depends on the project. That’s like asking what kind of development skills are needed. I wrote an article on this previously titled Defining the user experience FUNCTION: innovation through organizational design.
