Usefulness User Experience (UX) topic overview/definition

What is Usefulness?

If something is useful it can be used to achieve a particular objective. Designers will, generally, aim to deliver useful products. Usable, on the other hand, refers to the ease-of-use for a particular product and the more usable a product is the more likely it is that it will be used. Used, however, is the most important of these three concepts. If a design is not used, it doesn't matter how useful and usable it is. Designers are likely to want to examine how to transition from useful and usable in order for their work to succeed.
