A Quality Assurance Specialist monitors and records results from processes and procedures within manufacturing industries. Results are continually compared to predetermined expected ranges and any deviation from expected results leads to corrective measures. These quality checks ensure the ongoing reliability of the manufacturing process. 

Quality Assurance is part of the manufacturing quality system. It aims to prevent mistakes in the manufacturing process and defects in the finished product by implementing and monitoring processes and procedures. Individuals within the Quality Assurance department monitor these processes and procedures, take measurements and compare them to a predefined standard. Any deviation from the standard results in corrective action at the process or procedure.
