On our teams, which support different products, we have a varying degree of skill set within the team so that all skills are covered. For example, there are front-end and back-end developers, UI developers, and QA staff. Depending on the story, only some of the staff are capable of doing the work if the work requires a particular niche skill. And, in our case, our QA people don't do development and our other team members don't do QA.
