In their operations and production, enterprises typically undergo several kinds of audit (Audit), commonly including System Audit , Product Audit and Process Audit . From different angles, the three help enterprises find risks, verify conformity and drive continuous improvement, and all are important to an enterprise's sound operation and long-term development. Below we introduce the core differences and focus points of these three types of audit. What is a System Audit? A system audit is a holistic review of the organization's management system, which can be understood as 'auditing the whole system, auditing the overall picture.' Based on the concept of ISO 9001:2015 , its scope usually covers organizational context, planning, support, leadership, performance evaluation, operational control and improvement. System audits are often continuous , evaluating and reviewing the external and internal issues the enterprise faces as needed. Common focus points of a system audit include: Leadership and governance : management commitment, customer focus, quality policy, and the setting and implementation of roles and responsibilities in the management system. Operations and process control : from operational planning and design to process control; also including product release and mechanisms for controlling and disposing of products already in circulation. Customer satisfaction and continuous improvement : assessing customer satisfaction, and checking whether the enterprise's quality-improvement activities are effective and form a closed loop. What is a Product Audit? A product audit focuses on 'whether the product itself meets requirements,' verifying that it meets established standards by checking the product's key characteristics. The checks usually include dimensions, appearance and function and other pre-specified conditions, and are often combined with quality control (QC) activities. Taking a physical product as an example, a product audit might check: packaging and packaging markings label information (such as specifications, batch, etc.) production date and shelf life/expiry date sensory indicators such as smell and taste (applicable to food, etc.) the status of semi-finished goods and finished goods about to be delivered/marketed If the enterprise provides a service-type 'product' (for example, banking services), a product audit still applies, but the audit object shifts to the delivery characteristics of the service, for example: customer waiting time employee competence and service standards service efficiency and response speed, etc. What is a Process Audit? Compared with a product audit, a process audit is broader, focusing on 'how the product is made and delivered.' Its scope usually starts from raw-material receipt , runs through the production process, up to delivery to the customer/consumer ; it also observes supporting functions and resource conditions, such as human-resource allocation, facilities and environment. Process audits commonly use two audit paths: Forward audit : starting from incoming materials and auditing along the flow all the way to finished-goods shipment and distribution. Backward audit : sampling products already circulating in the market and tracing back to the upstream processes and control methods, to check whether the process is consistent, traceable and controllable. A process audit also looks at: the status of production equipment and facilities equipment maintenance mechanisms arrangements for handling and repairing equipment anomalies or breakdowns during production System, product and process audits are equally important. If an enterprise prepares fully and establishes standardized audit and improvement mechanisms, audits will be more efficient, more valuable and more readily translated into actionable improvement. When commissioning a third party to perform audits, certification and inspection, one should also choose a professional organization with the necessary qualifications, experience and broad service capabilities.

FAQ

What is the difference between the three common types of audit (system, product and process)?
From different angles, the three help enterprises find risks, verify conformity and drive continuous improvement. A System Audit is a holistic review of the organization's management system (auditing the whole system); based on ISO 9001:2015, it covers organizational context, planning, support, leadership, performance evaluation, operational control and improvement, focusing on leadership and governance, operations and process control, and customer satisfaction and continuous improvement. A Product Audit focuses on 'whether the product itself meets requirements,' checking key characteristics such as dimensions, appearance and function, and is often combined with QC. A Process Audit is broader, focusing on 'how the product is made and delivered' — from raw-material receipt through production to delivery — and can use a forward audit (from incoming materials to shipment) or a backward audit (sampling products already in the market and tracing back the upstream processes).
