Quality Assurance (QA) is a systematic process aimed at ensuring products and services meet defined standards and requirements before reaching customers. It involves planning, process design, testing, and documentation to prevent defects and enhance quality.

Key goals include increasing customer satisfaction, managing risks, reducing costs associated with rework, and ensuring consistency across outputs. QA also emphasizes continuous improvement and compliance with industry regulations.

By proactively identifying and addressing potential issues, QA helps organizations deliver reliable and high-quality products, ultimately adding value and fostering trust with customers.
