Overview

Software quality attributes are the features or properties that determine the overall software quality. They are also referred to as software quality characteristics or factors. These attributes can measure, evaluate, and assess software based on its functionality, performance, maintainability, usability, reliability, and security.

Software Quality Attributes

Some of the software quality attributes are as follows:

• Functionality
• Performance
• Usability
• Reliability
• Security
• Portability
• Compatibility
• Maintainability
• Scalability

Functionality

The ability of software to perform its intended functions and meet the requirements of its users.

Performance

The speed, efficiency, and responsiveness of software, as well as its ability to handle workload and scale.

Usability

The ease of use, learnability, and user satisfaction with the software.

Reliability

The ability of software to perform consistently and predictably, without failure or errors, under normal and abnormal conditions.

Security

The protection of software from unauthorized access, manipulation, and damage.

Portability

The ability of software to be used in different environments and platforms, without modification or adaptation.

Compatibility

The ability of software to work with other systems, software, and hardware components.

Scalability

The ability of software to handle increasing workload and user demand, without degradation of performance or quality.

Interoperability

The ability of software to exchange data and communicate with other systems, software, and services.

Maintainability

The ease with which software can be modified, updated, and repaired to meet changing needs or fix defects.
