How is software quality defined?

Software quality is fundamentally defined by the extent to which a product meets user needs. This definition encompasses various aspects of usability, functionality, performance, and reliability, which are crucial in determining whether the software effectively serves its intended purpose for the end-users. A software product with high quality is one that successfully fulfills the requirements and expectations of its users, ensuring that they can achieve their desired outcomes efficiently and effectively.

In contrast, other choices focus on specific metrics or outcomes that do not fully capture the holistic nature of software quality. For instance, the total number of defects in the software merely highlights potential issues but does not reflect how well the software performs for users. Similarly, the amount of time spent developing software emphasizes the development process rather than the quality of the final product. The number of satisfied customers can indicate success but doesn't necessarily provide a comprehensive view of software quality since satisfaction may stem from external factors unrelated to the software's functionality. Thus, the definition that centers on meeting user needs aligns best with a comprehensive understanding of software quality.
