Quality Assurance (QA) is a preventive, process-oriented approach that ensures quality is maintained throughout the software development lifecycle (SDLC). Rather than detecting defects, QA aims to prevent them by establishing best practices, frameworks, and testing methodologies.
By following structured testing methodologies, businesses can refine their QA processes, reducing time-to-market and minimizing post-release issues.
By catching issues early, QA reduces the burden on QC, leading to cost savings and faster development cycles. In Agile and DevOps environments, QA and QC are integrated into a continuous testing model, allowing for quicker defect detection and resolution.
