Not easy to evaluate users because :
1. Context: UX may change when the context changes, even if the system does not change. Context in the UX domain refers to a mix of social context.

2. User: UX is dynamic, as the person experiencing the system is dynamic. This refers to users motivation, mood, preference... when user use the system.

3. System: A user’s perception of the system’s properties naturally influences UX. For example, system’s functionality, aesthetics, designed interactive behaviour.

Rather than it's a broad collection of user-centric issues that cut through the full extent of a project.

According to the ISO user experience includes all the user's emotions, beliefs, preferences, physical and psychological response and behavior that occur before, during and after use.

UX and Usability are relevant, but not same.
UX is the cycle of processes Research, Design and Evaluation.
