What is the Role of ISO 9001 in an Internal Audit?

Clause 9.2 of ISO 9001:2015 states that “the organization should conduct internal audits at planned intervals to provide information on whether the Quality Management System conforms to the organization’s own requirements, the requirement of ISO 9001:2015 standards and is effectively implemented and maintained.” Essentially ISO recommends conducting an internal audit to ensure that the organization is compliant with regulatory requirements and take corrective action if necessary.

How to Perform a Quality Control Audit in a Manufacturing Business?

There are five critical steps to properly perform a manufacturing process audit. Here’s a checklist of everything one needs to do to learn how to audit the manufacturing business.

Select Audit Type:
Before starting the audit, identify the focus and goal that needs to be achieved. Once the goal is set, it is easy to ascertain which of the following audits must be performed.

  • System audits evaluate a company’s management systems and ensure that all elements and processes are effective. This audit also ensures that the development and implementation of the systems consistently meet specified requirements. For example, a QMS Audit will review its existing quality system to comply with company policies and the required regulations.
  • Product audits examine a company’s services and products to ensure they’re compliant with government policies, performance standards, and company quality standards.
  • Process audits review all company processes to ensure efficiency within their established limits. This audit also checks operation time and responsiveness and the effectiveness of each procedure and process specifications.
  • A first-party audit is an internal audit designed to evaluate the performance of the organization’s objectives, identify problem areas and find processes that need continuous improvement. This audit is conducted by employees who take on the auditor’s role.
  • The second-party audit is an external audit conducted by auditors hired from outside the organization. These independent audits may impact the buying decisions of the customer.
  • A third-party audit is performed by an external organization. This is done to ensure there is no conflict of interest resulting in recognition, license approval, certification, or penalty being issued by the third-party organization.

List Tasks and Perform Audit:
Based on the audit that should be conducted, the auditor will have to perform specific tasks to accurately evaluate a particular area’s performance and effectiveness. When it’s time to perform the audit, preparing a checklist that has each task listed in a series of steps is recommended.

Record Findings in an Audit Report:
Once the audit is completed, the auditors must create an audit report to document all the findings. This report must be thoroughly reviewed before planning the next step.

Determine and Perform Corrective Action:
Based on the findings from the reports, determine and perform corrective actions to remedy the issues listed. It is advised to note everything that will be done to resolve each problem in a separate report. This will help keep track of the methods that have been tried and help choose suitable corrective actions in the future.

Schedule a Follow-Up Audit:
After corrective action is carried out, conduct another audit to measure changes instituted by the corrective action.

  • If system processes, performance, or products show improvement, record the findings in a separate audit report and discuss it before closing the audit.
  • If the findings indicate minimal or no changes in any processes, performance, or products, make a note in a separate audit report to determine the subsequent corrective action needed. Continue this pattern until there is an improvement.
