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 how easy and satisfying a system is for users to interact with and accomplish their tasks. It involves elements such as the intuitiveness of the interface, the efficiency of the interactions, and the overall satisfaction experienced by the users while using the software.

When evaluating usability, factors like learnability, memorability, error frequency, and user satisfaction come into play, making it a central concept in user-centered design. This focus on the end-user experience ensures that the software is not only functional but also enjoyable to work with, directly impacting user engagement and productivity.

Other options such as understandability relate more to how well a user can grasp the system's functionality, accessibility refers to how easily all users, including those with disabilities, can use the software, and effectiveness generally measures how successful a user is at completing tasks. While these are important aspects of software quality, they do not encompass the full scope of user experience defined by usability.
