The user puts the u in UX.
What defines UX in general and usability in particular, is the observation of people interacting with products–software, hardware, and websites.
For decades, UX professionals have worked to convince executives and product managers of the importance of involving users in the design and evaluation of product experiences.
We stress the necessary difference between usability testing and traditional market research activities (such as surveys and focus groups) which focus more on attitudes and predilections rather than on the behavior users’ exhibit as they use an interface.
