QA involves rigorous testing procedures to identify defects, bugs, or inconsistencies in software, products, or services. This testing can include functional, performance, security, and compatibility testing, among others.

QA teams establish and maintain documentation of quality standards, procedures, and guidelines. This documentation ensures that everyone involved in the development process understands and adheres to the established quality criteria.

QA acts as a bridge between development teams and stakeholders. They provide valuable feedback to developers and project managers about quality issues, helping to resolve problems efficiently and maintain clear communication channels.

Automation tools and frameworks are often employed in QA to streamline testing processes, increase efficiency, and reduce human error. Automated testing can cover repetitive tasks and allow QA engineers to focus on more complex scenarios.

QA assesses and manages risks associated with the development process, ensuring that potential issues are identified and mitigated early to prevent costly problems later in the project lifecycle.

In addition to functional testing, QA also encompasses UX testing to ensure that the end-users have a smooth and satisfying experience with the product or service.
