Maintaining ISO 9001 certification involves a number of steps and activities that need to be undertaken on an ongoing basis. Here is a general overview of the process for maintaining ISO 9001 certification:

Conduct regular internal audits: Regular internal audits should be conducted to identify any non-conformities or areas for improvement in your quality management system. These audits should be conducted by trained and competent personnel and should cover all aspects of the ISO 9001 standard.

Corrective action: Any non-conformities or areas for improvement identified during the internal audit should be addressed through corrective action. This involves identifying the root cause of the problem, implementing a corrective action plan, and verifying that the corrective action has been effective.

Management review: The senior management team should conduct regular reviews of the quality management system to ensure that it continues to be effective and is meeting the needs of the organization and its stakeholders.

Continual improvement: The ISO 9001 standard emphasizes the importance of continual improvement. This means that the organization should be looking for ways to improve its processes, products, and services on an ongoing basis.

Monitor and measure performance: The organization should have processes in place to monitor and measure the performance of its quality management system. This includes setting measurable objectives and targets, collecting data, and analyzing the results.

External audits: The organization will be subject to regular external audits by a certification body to ensure that it continues to meet the requirements of the ISO 9001 standard. The external audit will typically be conducted annually, although the frequency may vary depending on the certification body and the organization's risk profile.

By following these steps and maintaining a robust quality management system, the organization can continue to meet the requirements of the ISO 9001 standard and maintain its certification.
