Software Development Life Cycle
Quality Assurance (QA) is a systematic process aimed at ensuring that products and services consistently meet specified requirements. It encompasses all planned and systematic activities implemented within a quality system to ensure that a product or service is of the type and quality that the customer requires, and that the organization can justify. QA involves reviewing, testing, inspecting, and auditing processes and outputs to detect errors, improve efficiency, and eliminate waste in order to maintain high standards and meet business objectives. In the contexts of Information Technology Management and Business, Quality Assurance plays a critical role in ensuring customer satisfaction and building trust, while also contributing to operational excellence and financial success. QA is an ongoing process that involves continuous improvement and adaptation to changing requirements and technologies. It is closely related to Quality Control (QC), which focuses on specific measurements and inspections of outputs to ensure compliance with established standards, and both are essential components of a robust quality management system.
