Quality Assurance (QA) is a systematic process used to ensure that products and services meet specified requirements and standards, published by international bodies such as ISO/IEC and maintained through frameworks like the SQuaRE series. It solves the problem of inconsistency and defect proliferation in development and manufacturing by establishing repeatable, auditable processes. Within the technology stack, QA integrates across the software and systems development lifecycle to uphold reliability, compliance, and performance. Core components include ISO/IEC 25000 for quality management, ISO/IEC 25010 defining the quality model for software and systems, ISO/IEC 25020 for quality measurement, ISO/IEC 25030 supporting quality requirements specification, and ISO/IEC 25040 providing the framework for quality evaluation. Specialized extensions such as ISO/IEC TS 25058 offer guidance for evaluating AI systems, ensuring adaptability to emerging technologies while maintaining rigorous assessment standards. Quality Assurance is for software engineers, QA analysts, compliance managers, and development teams who require structured methodologies to prevent defects, meet regulatory standards, and deliver reliable products. These practitioners benefit from standardized frameworks that enable consistent evaluation, traceability, and continuous improvement across complex development environments.
