Their responsibilities include analysis of the context of use, specifying user requirements, producing design solutions - in particular prototypes - and carrying out usability evaluations.

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
Task
A set of activities undertaken in order to achieve a specific goal.
Notes:
1. Most tasks can be subdivided into subtasks - that is, activities.
2. A subtask does not in itself achieve a goal from the user's point of view but is a necessary decision or action to reach the user's goals.
3. Most subtasks lead to choices or inputs by the user when using the interactive system.
4. Some subtasks can be subdivided into smaller subtasks.
5. Subtasks are unsuitable as usability test tasks, because they are very specific
