Explanation
See page 12 in https://uxqb.org/wp-content/uploads/documents/CPUX-F_EN_Curriculum-and-Glossary.pdf User experience A user's perceptions and responses that result from the use and/or anticipated use of an interactive system.
Notes:
1. Users' perceptions and responses include the users' emotions, beliefs, preferences, comfort, behaviours, and accomplishments that occur before, during and after use.
2. User experience is a consequence of brand image, presentation, functionality, system performance, interactive behaviour, and assistive capabilities of the interactive system. It also results from the user's internal and physical state resulting from prior experiences, attitudes, skills, abilities and personality; and from the context of use.
3. Usability criteria can be used to evaluate aspects of user experience.
4. Usability is mainly about the interaction with the interactive system. User experience also takes into account what happens before and after the interaction through to final use and recollections of use. See the examples below.
5. User experience is mainly about satisfaction and fulfilment of expectations.
6. User experience is often referred to as UX.
7. The following figure shows the relationship between user experience and usability. Usability is effectiveness, efficiency and satisfaction during actual use, while user experience is the satisfaction or dissatisfaction during anticipated use, actual use and after use.

Explanation
Usability evaluation is a part of the phase: "Evaluate the design against user requirements" Usability tests may occur at any time during the human-centred design process, from early analysis through interactive system delivery and beyond. Usability tests may be based on paper sketches or display mock-ups, as well as on interactive systems under design and completed interactive systems.
