In the context of UX, how is usability defined?

Usability in the context of user experience (UX) refers to how easy and efficient a product is to use. This concept encompasses various factors, including how intuitive the product's interface is, how quickly users can accomplish their tasks, and how satisfying the overall experience is for the user. A product with high usability enables users to navigate it with little confusion or frustration, ultimately leading to a more positive interaction and higher user satisfaction. The focus on ease and efficiency directly impacts the user’s ability to achieve their goals effectively, making usability a critical aspect of UX design.

In contrast, the other options do not align with the definition of usability. Aesthetic beauty relates more to the visual appeal of a product rather than how functional it is. Complexity of technology addresses the technological aspects but does not assess the user's experience with the product itself. Pricing strategy is also separate from usability, as it concerns the product's market position rather than the user's interaction with it.
