Hi All, 

Agree with Rodrigo UX is not UI but not able to excess the link .Below are the some addon on this .                            

                                            Responsibilities of each position.

Despite the philosophical similarities, practical application in the marketplace is very different. The three primary differences between UX and UI designers are:

UX deals with the purpose and functionality of the product. UI deals with the quality of the interaction that the end-user has with the product.


UI design has an artistic component as it relates to the design and interface with the product. It affects what the end-user sees, hears, and feels. UX has more of a social component for market research and communicating with clients to understand what their needs are.

UX focuses on project management and analysis through the entire phase of ideation, development, and delivery. UI has more of a technical component to produce the design components for the finished product.
UX and UI are not areas to skimp on. Regardless of the definitions and division of labour, they are both essential parts of product development and delivery. Research shows that customer experience drives revenue growth. UX and UI are an investment in the product or service.

Usability

Usability” refers to the ease of access and/or use of a product or website. It’s a sub-discipline of user experience design. Although user experience design (UX Design) and usability were once used interchangeably, we must now understand that usability provides an important contribution to UX.
A usable interface has three main outcomes:

 1) It should be easy for the user to become familiar with and competent in using the user interface on the first contact with the website. If we take a travel agent’s website that a designer has made well, the user should be able to move through the sequence of actions to book a ticket quickly.

 2)It should be easy for users to achieve their objective through using the website. If a user has the goal of booking a flight, a good design will guide him/her through the easiest process to purchase that ticket.

 3)It should be easy to recall the user interface and how to use it on subsequent visits. So, a good design on the travel agent’s site means the user should learn from the first time and book a second ticket just as easily.



Thanks
