Abstract:

In my last column, I suggested that being a manager of UX is no better—and no worse—than being a great designer or user researcher, but the roles are very different. In fact, as the book The First 90 Days [1] points out, the skills that make you successful as an individual contributor are not the same skills you need as a leader.
