Which of the following is NOT one of the usability objectives?

Creativity is not considered one of the core usability objectives. Usability objectives focus on aspects that make a product or system user-friendly and efficient. Effectiveness refers to how well users can achieve their goals with a product, emphasizing the success rate in completing tasks. Learnability addresses how easy it is for new users to accomplish tasks on the first attempt, highlighting the importance of intuitive design. Attitude reflects the users' feelings and satisfaction towards the product, considering their overall experience.

While creativity can play a role in design, it is not a standardized usability objective. Usability objectives are concerned with measurable aspects of user interaction, while creativity pertains more to the design and innovation process rather than direct user experience.
