What is defined as an independent review comparing quality performance with a established standard?

The correct answer is the choice that defines an independent review that compares quality performance with established standards, which is known as a quality audit. A quality audit is a systematic examination of a quality system carried out by an internal or external auditor. It assesses whether the quality performance meets the defined criteria and standards.

Quality audits are essential tools in manufacturing and other industries because they help organizations ensure compliance with internal guidelines and external regulations. This process enables organizations to identify areas of improvement and ensure that quality systems are functioning effectively, leading to enhanced product quality and customer satisfaction.

In contrast, quality control focuses on the operational techniques and activities used to fulfill requirements for quality, while quality assurance encompasses the systematic processes to ensure that quality requirements are met. A quality management system is an overarching framework that includes both quality assurance and quality control activities.
