User experience (UX) design is the process that design teams go through to make the user experience for a product useful for potential clients. We can probably all think of poorly designed products that give us an unpleasant user experience. UX design is the process of improving such designs, making them more user friendly. It is related to, yet different from, user interface (UI) design that focuses solely on designing the looks or style of a product. UX design covers much more.
