Websites, apps, software, and other digital products are more likely to be adopted by users if they're useful and easy to navigate. While you need programmers to build your products and interaction designers to make them visually appealing, it's the user experience (UX) designer who makes the difference between good user experiences and poor ones.
UX design is human-centered, putting the user at the core of a product from the earliest stages of development. This is the opposite approach to making a product and hoping people use it. UX design involves identifying a user's needs, expectations, and behaviors, and developing appropriate design solutions. Based on significant user research and testing, a UX designer's work ensures there's logic behind each design element so the overall product makes sense for the user.
UX designers are often confused with user interface (UI) designers, because the two work together closely. Typically, a UX designer develops a design prototype. The UI designer takes the design and creates the visual look and feel of the components the user interacts with.
Once the UI is created, developers and programmers write the code so the product performs the tasks a user requests.
