UX DESIGN IS ABOUT
MAKING THE EXPERIENCE
OF USING A PRODUCT
AS POSITIVE AS POSSIBLE
The emphases of UX design is on utility, ease of use and efficiency with which users interact with websites, apps or services. Its aim is to attract attention and focus, and to make the user's journey from home page to checkout as effortless as can be.
UX designer's job is to be the conduit that bonds the product team, and then interprets designs to developers who in turn put them into products.
The core of successful design is not only about what the product looks like, but also what it feels like to the user. If it's not taxing to the user, then the UX designer's job is done.
If it is, keep iterating, keep exploring until it isn't.
UX design is above all a people-focussed craft. Empathy is key. UXers job is to try to understand why users behave the way they do, and not to try to influence or change their behaviour, but accommodate it in the way the product works, looks and feels to the user.
