All work directly related to system certification should primarily focus on the following:
ISO 9001 mandates comprehensive planning and development of the certification work plan; requires information management and selection of a certification body; necessitates negotiations with the chosen certification body and signing a certification contract or agreement; demands submission of the quality assurance manual; requires preparation for on-site inspections and welcome inspections; necessitates accepting on-site inspections and providing timely feedback; requires organization of corrective actions for non-conformities; requires passing the system certification to obtain the certification certificate; mandates prevention of complacency and maintaining the quality system's continuous improvement; and necessitates corrective actions and welcoming follow-up inspections.
In practice, during ISO9001 certification audits, it is common to find that many clients can identify some issues on their own, such as internal audits, evaluations, inspections, returns and exchanges, and complaints. They have also taken some measures, but many of these are superficial, addressing the issue at hand and merely correcting the non-conformities. Afterward, there are often repeated occurrences. For example, surface oil stains on injection molded parts. Clause 8.5.2 of the ISO9001 standard clearly specifies requirements for corrective actions. When problems are identified, not only should they be improved, but also improved effectively. If resources are invested to solve the problem, it should be addressed thoroughly. Effective problem-solving lies in eliminating the root cause of the issue.

A fully integrated management system compliant with ISO 45001, operating under certain methods and approaches within a unified framework.
There are narrow and broad definitions of integrated management systems. The narrow sense refers to integrated management systems such as the integration of the aforementioned "two standards" or the integration of the "three standards". The broad sense includes intensive integrated management systems.
Intensive integrated management system, an expansion and enhancement of the integration management of "multiple standards" such as QHSE (Quality Management System, Environmental Management System, Occupational Health and Safety Management System). The integrated management system formed by integrating QHSE and other "multiple standards" is a standalone system; however, from a holistic perspective and system objectives, when viewed as a whole enterprise, QHSE management still operates as a multi-system alongside other various specialized management within the company. In the intensive integrated management system described in this book, quality management, environmental management, and occupational health and safety management are merely an important component of the management system.

The Role of ISO9001 Procedure Documents.
Maintain control over quality activities. Establish specifications for all activities affecting quality; - Define the methods and criteria for evaluating these activities to ensure they are under control.
Define the responsibilities, authorities, and relationships of personnel involved in quality activities: duties, rights, interrelations.
As the basis for executing, verifying, and reviewing quality activities. The provisions of the program are implemented in actual operations; evidence of the execution should be retained; the actual operations are to be reviewed against the program to ensure compliance.

The output of the management review should include relevant decisions:
Continuous suitability, adequacy, and effectiveness of the occupational health and safety management system in achieving anticipated results; opportunities for continuous improvement; any requirements for changes to the occupational health and safety management system; required resources; necessary measures; opportunities for integrating the occupational health and safety management system with other business processes; any conclusions related to the organization's strategic direction.
Purpose of ISO 9001 Certification
Supplier confirms that its quality system complies with the specified quality system requirements. Under contract conditions, the supplier shall demonstrate to the specific customer that its quality system meets the quality system requirements stipulated in the contract. In the case of third-party certification, the supplier shall verify with the certification body that its quality system meets the requirements of the applied quality assurance model.
