Quality Attributes of Software

Quality attributes of software are non-functional requirements that define the user experience, interoperability, and performance of a product. High-quality software is characterized by its ability to meet or exceed users’ expectations regarding functionality, reliability, maintainability, usability, and security. 

Functionality is the capability of software to perform a set of defined tasks or functions. With that being said, the end product must meet users’ requirements by delivering the necessary features, functionality, and performance without defects and errors. These requirements are crucial as they define the software’s core purpose, hence the primary determinant of its quality.

Reliability is the degree to which software can function under specific conditions for a specified period, meaning how well it can handle errors, crashes, and failures. A product must maintain its functionality over an extended period, often referred to as uptime, while minimizing downtime.

Maintainability refers to the ease of making modifications or updates to the software, as well as fixing errors and bugs. This attribute is substantial: it enables developers to create products without making drastic changes that usually become very expensive.

Usability relates to how easy it is for users to learn and operate the product. Characteristics like friendly interfaces, well-organized menus, intelligible error messages, update alerts, etc., define excellent usability.

Security involves protecting software from unauthorized access, attacks, and modifications. The end product must be shillded from hacks, and measures should be implemented to ensure that unauthorized users can’t access or change essential data files. 

QA Methods

QA methods differ depending on the end goal. Below are some of the most common ones:

  • Unit testing checks individual software components or modules to determine whether each performs as intended. It is performed throughout the development cycle (including during coding) to ensure developers stay on track and accurately meet product specifications.
  • Integration testing checks how various software components work together when integrated into the whole system. This kind of testing verifies that the communication, coordination, and data exchange between individual modules.
  • Functional testing checks the software’s functionality by verifying whether the system meets the specified requirements accurately.
  • Acceptance testing verifies whether the developed software fulfills the acceptance criteria and is ready for delivery. It usually involves participation from business users to ensure that the final product meets their needs.
  • Regression testing helps verify that changes to the software do not adversely affect the existing functionality. This sort of testing is usually conducted after updates checking whether the existing functionalities are working correctly.
  • Performance testing helps ensure that the software meets the desired level of performance under specific conditions. It includes testing the product under diverse conditions to verify it can handle the expected user load, processing times, and response times.
  • Security testing ensures the end product is secure and the data is protected against unauthorized access, theft, and malicious attacks.
