One of the most common misconceptions people have is that User Experience Design is all about usability. It’s easy to see why – usability means that a product is both usable and useful.
When you walk into an empty room, you can instantly imagine what purpose it will serve. Glance around and you get an idea for how to turn that space into anything that you want it to be. You can use it as a living room, an office, or a bedroom. It all depends on what furniture you choose and where you put it. The empty room is usable, but it’s not useful until you fill it.
In software, “the room” a user enters is never empty. Every software product has a user-facing side that was built for people to interact with. That interaction becomes an experience they go through when they use the product. It’s the UX designer’s job to make that experience a great one.
