UX (user experience)

User experience (UX) is the art of planning a product's design so that interactions with the completed product will be as positive as possible. 

This includes an end user's interaction with and attitude toward a given IT system or services, including the interface, graphics and design. IT leaders concerned with UX ask questions to determine what their users need and value, and compare those findings to their IT system's current abilities and their limitations.

User experience design (UXD or UED) addresses all aspects of how a product or service is perceived by users. Elements of user experience design include:

• Visually pleasing and interactive design;
• An information architecture that presents information in an organized fashion, paying special attention to features such as design and navigation themes;
• Accessibility
• HCI
• Ergonomics
• Utility
• Performance.

User experience strategies should be constantly modified as usage circumstances shift and individual systems are modified in usage context. User experience testing is often employed to reassess UX.
