An Audit is defined as on-site verification activity, such as inspection or examination, of a processor quality system. Quality Audit is the process of systematic analysis of a quality system carried out by an internal or external quality auditor, or an audit team. Quality Audits are performed at predefined time intervals and ensure that the institution has clearly defined internal system monitoring procedures linked to effective action. Audits are an essential management tool to be used for verifying objective evidence of processes.
