Software Quality Assurance (SQA) is a systematic process that ensures the quality of software products throughout their development lifecycle. It involves various activities, including testing, code reviews, and process audits, to identify and fix defects before the software is released. SQA aims to enhance the reliability, performance, and usability of software. By implementing SQA practices, organizations can minimize risks and improve customer satisfaction. This process not only focuses on the final product but also emphasizes the importance of quality in the development process itself. Ultimately, SQA helps deliver software that meets or exceeds user expectations.
