What term refers to the user’s ability to find the software pleasant and straightforward to use?

The term that refers to the user's ability to find the software pleasant and straightforward to use is usability. Usability encompasses various aspects of user experience, including how easy and satisfying a product is to use. This concept is critical in software development, particularly in Agile methodologies, where the focus is on delivering value to end users. Usable software allows users to efficiently accomplish tasks, contributes to user satisfaction through a pleasant experience, and reduces frustration, all of which enhance the overall effectiveness and acceptance of the product.

Understandability pertains to how well users can comprehend the information and functionality presented by the software, but it does not capture the full experience of how enjoyable or straightforward the software is to use. Accessibility focuses on how well software accommodates users with disabilities, ensuring that all users can interact with it effectively. Effectiveness refers to the accuracy and completeness of user tasks, but it does not address the subjective pleasure or ease of use that defines usability. Thus, usability is the most comprehensive term in connection with user experience in this context.
