UX aims for that sweet spot where user needs & business needs overlap.

UX (User experience) encompasses all aspects of the end-user's interaction with company, its services, and its products. A great user experience meets the exact needs of the customer, without fuss or bother, simply giving customers what they say they want. UX is the: what, when, where, why, how, and who of a product. Pretty much everything that affects a user's interaction with that product.
