The user experience of your products is only as good as the knowledge and skills of your UX staff.
As organizations realize how important the user experience is to the success of their products, UX teams are expanding. People come to role of UX from more and more diverse backgrounds. Some UX staff used to be web designers. Others used to be visual designers. Others used to be usability testers. The plus side of this is that you may find yourself with a team that has a wide variety of skills. That sounds like an advantage, and it is. But it has a down side too. As the diversity of your team increases, it’s possible that particular individuals may have gaps in their skill-set. And the team loses a sense that there is a core set of skills and knowledge that everyone possesses.
