Quality Assurance

Definition

Quality assurance refers to the systematic process of ensuring that products and services meet specified requirements and standards. It focuses on preventing defects and enhancing the reliability of processes, ultimately leading to higher customer satisfaction and trust. In the context of measurement technologies, this concept is critical as it ensures the precision and accuracy of data collected through measurement instruments.

5 Must Know Facts For Your Next Test
