Software Quality Assurance (SQA) is a systematic process that ensures the quality of software products throughout their development lifecycle. It involves various activities, including planning, monitoring, and evaluating the software development process to identify defects and ensure that the final product meets specified requirements. SQA aims to enhance the reliability and performance of software by implementing best practices and standards. SQA encompasses different methodologies and tools, such as automated testing, code reviews, and quality audits. By integrating SQA into the development process, organizations can reduce risks, improve customer satisfaction, and deliver high-quality software that meets user needs and expectations.
