Auditors ascertain the existence or lack (usually tangible) of a practice in a specific or narrow scope of determinants as measured against predetermined or prescribed standards. The final outcome of an audit is usually a yes/no consideration. A quality auditor is a professional who understands the standards and principles of auditing and the auditing techniques of examining, questioning, evaluating, and reporting to determine a quality system’s adequacy and deficiencies. The quality auditor analyzes all elements of a quality system and judges its degree of adherence to the criteria of industrial management and quality evaluation and control systems.
