During their operations and production, businesses typically undergo various audits, the most common of which include: system audits.System Audit、Product AuditandProcess AuditThese three elements help companies identify risks, verify compliance, and drive continuous improvement from different perspectives, which is of great significance to the company's sound operation and long-term development.
The following section will introduce the core differences and key focuses of these three types of audits.
What is a system audit?
System AuditIt is a holistic review of the organization's management system, which can be understood as "reviewing the entire system, a comprehensive review." Based on...ISO 9001:2015The concept typically covers multiple aspects, including organizational environment, planning, support, leadership role, performance evaluation, operational control, and improvement.
System audits often havePersistenceIt will address the challenges faced by enterprises as needed.External and internal issuesConduct assessments and reviews.
Common areas of focus in system audits include:
Leadership and GovernanceManagement commitment, customer focus, quality policy, and the establishment and implementation of roles and responsibilities within the management system.
Operations and process controlThis includes everything from operational planning and design to process control; it also includes product release and the control and disposal mechanisms for products already in circulation.
Customer satisfaction and continuous improvementAssess customer satisfaction and examine whether the company's quality improvement activities are effective and form a closed loop.
What is a product audit?
Product AuditThe focus is on whether the product itself meets the requirements, verifying its compliance with established standards by examining the product's key characteristics. The checks typically include:Size, appearance, functionIn addition to other pre-defined conditions, and often combined with quality control (QC) activities.
Taking physical products as an example, product audits may examine:
Packaging and Packaging Labeling
Label information (such as specifications, batch number, etc.)
Production date and shelf life/expiration date
Sensory indicators such as odor and taste (applicable to food, etc.)
Status of semi-finished products and finished products about to be delivered/launched
If the company providesService-oriented "products"(For example, banking services) Product auditing still applies, but the audit object shifts to the delivery characteristics of the service, such as:
Customer wait time
Employee Competency and Service Standards
Service efficiency and response speed, etc.
What is a process audit?
Compared to product audits,Process auditIt has broader coverage, focusing on "how products are made and delivered." Its audit scope typically ranges from...Raw material receivingFrom the beginning, throughout the entire production process, until the final product.Delivery to customers/consumersAt the same time, we will also observe supporting functions and resource conditions, such as human resource allocation, facilities and environment.
Two common audit paths are used in process auditing:
Forward auditFrom the moment the materials arrive, the entire process is reviewed and approved until the finished products are shipped and distributed.
Backward auditingBy sampling and tracing products already in circulation in the market, we can reverse-engineer their upstream processes and control methods to verify whether the process is consistent, traceable, and controllable.
Process audits will also focus on:
Production equipment and facilities status
Equipment maintenance and upkeep mechanism
Arrangements for handling and repairing equipment malfunctions or damage during production
System audits, product audits, and process audits are equally important.。
If companies can adequately prepare and establish standardized audit and improvement mechanisms, audits will be more efficient, more valuable, and more likely to translate into actionable improvements. If third-party organizations are engaged to perform audits, certifications, and inspections, qualified and experienced professional organizations with broad service coverage should be selected.
