Quality audit is the process of systematic examination of a quality system carried out by an internal or external quality auditor or an audit team. It is an important part of organization's quality management system and is a key element in the ISO quality system standard, ISO 9001 (Wikipedia 2009).
A quality audit is a systematic and independent examination to determine whether quality activities and related results comply with planned arrangements and whether these arrangements are implemented effectively and are suitable to achieve objectives (ANSI/ISO/ASQC A8402-1-1994).
An audit may be classified as internal or external, depending on the interrelationships that exist among the participants.
- A first party audit is performed within the organization by auditors who are employed by the organization to measure its strengths and weaknesses against its own procedures and methods and/or external standards adopted by the auditee organization (voluntary) or imposted (mandatory).
- A second-party audit is an external audit performed at a supplier by a customer or a contracted (consulting) organization on behalf of a customer (i.e. supplier audit). (Westcott 2006).
- A third-party audit is performed on a supplier or regulated entity by an external party other than a customer, usually compensated for the audit. (Westcott, 2006).
Types of audits
- A product quality audit is an in-depth examination of a particular product or service to evaluate whether it conforms to product specifications, performance standards and customer requirements (Westcott 2006).
- A process quality audit examines a single process or activity to verify that the inputs, actions and outputs are in accordance with requirements established by procedures, work instructions, or process specifications (Westcott 2006).
