In layman’s terms, an ISO audit is a check to guarantee that you are doing what you claim you are doing.

Throughout an ISO audit

  • Check that the management system complies with the applicable ISO standard.
  • Check to ensure that the activities performed to satisfy the organization’s quality objectives are appropriate.
  • Check to see whether any issues with the management system have been resolved.
  • Examine the system for any enhancements that can be made.

There are three major types of ISO audits:

First-party auditing is also known as internal auditing. These audits are normally performed internally by your own staff who have been trained to perform internal audits, or they may be performed on your behalf by an external organization if you do not have the necessary internal resources.

Second Party Audit- also known as a retailer audit. Lead auditors often conduct such audits with the company and are designed to ensure that the businesses that offer you products/services do what they say they do. Again, if you lack internal resources, these audits may be performed by an outside firm.

Third-party auditing is sometimes known as certification auditing. These audits are frequently performed by an inspector from the Certification Body. These audits are performed in order to get certification from a recognized authority in accordance with the appropriate ISO standard.

Audits to all ISO standards, including ISO 9001, ISO 14001, OH&S 18001, ISO 13485, TS 16969, and ISO 27001, can (and occasionally must) be done.

What Happens If Your Organization Fails an ISO Audit?

When an organization fails an ISO audit, it must take corrective action to address the issues. There are several things a corporation can do to resolve the challenges and obtain ISO certification, including:

Examine the situation: The non-conformance report from the auditor will state whether there was a “small non-conformance” or a “large non-conformance.”

A minor nonconformance indicates that the auditor discovered modest flaws in the enterprise’s ISO compliance. For example, perhaps the organization failed to comply with one of the ISO requirements, or an individual lacked the essential documents to verify compliance.

A significant nonconformance shows that the management system under scrutiny has a catastrophic fault and is lacking something crucial that is required to meet company goals or safeguard customers. For example, the corporation may have failed to execute a vital practice or requirement, or the organization may have failed to take the appropriate preventive or corrective action to assure compliance.

Take corrective action: A minor non-conformance will not prohibit an organization from gaining ISO certification as long as it immediately takes corrective action to address the issues identified in the report. A serious non-conformance, on the other hand, will prevent certification. The firm will need to schedule another audit in order to gain certification.

Audits by a Third Party

The certification audit is performed by a third-party auditor. When an organization seeks ISO certification, it often undergoes a third-party audit. A certification body auditor determines if a company conforms with the relevant ISO standard during the certification audit. If this is the case, the certifying body auditor will issue the certification.


The American Society for Quality classifies audits into three types: process audits, product audits, and system audits.

A process audit ensures that a company’s procedures fulfill the standards of the specific standard for which it is seeking certification.

The auditor may, as part of this audit,:

Check for compliance with specified parameters such as time, precision, temperature, pressure, composition, responsiveness, amperage, and component combination.

Examine the resources (equipment, materials, and people) used to convert inputs into outputs, as well as the environment, methods (procedures, instructions), and metrics collected to determine process performance.

Examine the appropriateness and efficacy of the process controls provided via procedures, work instructions, flowcharts, training, and process specifications.

A product audit examines a specific product or service, such as hardware, processed material, or software, to see whether it complies with the applicable standard.

A system audit is an examination of a management system. A system audit is a documented activity that verifies, through the examination and evaluation of objective evidence, that applicable elements of the system are appropriate and effective, and that they have been developed, documented, and implemented in accordance with and in conjunction with specified requirements.

Because the majority of ISO standards that are certifiable govern systems, such as quality management systems, information security management systems, food safety management systems, and environmental management systems, ISO certification audits are often system audits.
