Quality Assurance (QA) in software development ensures products meet requirements and are defect-free. It emphasizes proactive processes over reactive measures, focusing on prevention. QA is vital for customer satisfaction, cost efficiency, risk mitigation, and regulatory compliance. Key processes include requirements analysis, test planning, test design, and test execution. These processes involve creating detailed test cases and running various tests, both manual and automated, to identify issues early. By integrating QA throughout the development lifecycle, organizations can enhance software quality, reduce costs, and deliver better user experiences, ultimately leading to greater customer loyalty and trust.
