What does operability in a software product refer to?

Operability in a software product refers to the control a user has over its functions. It emphasizes the user's ability to effectively interact with the software to accomplish tasks. This includes aspects such as how intuitive the user interface is, how easily a user can access features and perform actions, and the overall user experience when engaging with the software.

While other factors like aesthetic design, performance under load, and security are vital to the overall quality of a software product, they do not directly relate to operability. Aesthetics can influence user engagement but do not determine how well an individual can operate the software. Similarly, performance under load can affect usability but is more focused on the software's efficiency in managing resource demands rather than how it allows user interaction. Security measures are essential for protecting data and user privacy but do not pertain to the level of control a user has while using the software. Thus, the concept of operability centers mainly on user control and interaction capabilities.
