Select ALL qualities identified as attributes of good software.

### Why this is right - **Maintainability** is the ability to modify and support the software. - **Dependability** concerns whether users can rely on the software. - **Efficiency** concerns its use of resources and time. - **Usability** concerns how effectively people can use it. ### The concept These are software quality attributes: they describe properties of the product, not just whether it runs. Physical durability is not among the listed attributes, and software does not physically wear out in the way a mechanical part can. ### The other options - **E. Physical durability**: This is a tempting quality for physical products, but the source lists maintainability, dependability, efficiency, and usability. ### Terms - **Maintainability**: How readily software can be corrected or changed. - **Dependability**: The degree to which software can be trusted to behave as needed. - **Usability**: How readily intended users can use the software. ### Remember Recall the four listed attributes: maintainability, dependability, efficiency, and usability.
