1. **Identify Key Processes**: Determine the essential processes needed for the QMS and their application throughout the organization.

2. **Define Roles and Responsibilities**: Clearly outline who is responsible for each process and what their roles entail.

3. **Document Procedures**: Write documents that the organization concludes are necessary for the QMS, such as procedures, guidelines, plans, and forms.

4. **Ensure Consistency and Traceability**: Document process flows, work instructions, and records to maintain consistency and traceability.

5. **Establish Criteria and Methods**: Define criteria and methods to ensure effective operation and control of processes.

6. **Monitor and Measure Performance**: Implement processes for monitoring, measurement, and performance evaluation.

7. **Encourage Continuous Improvement**: Establish a continuous improvement cycle, encouraging feedback and making necessary adjustments.

8. **Engage Leadership**: Ensure leadership is engaged to drive the QMS and align it with business goals.

9. **Use a Structured Format**: Consider using a common structure for procedures, including purpose, scope, users, reference documents, process explanation, and records.

10. **Adapt to Organizational Needs**: Develop procedures in a way that suits the organization and the employees executing them, without unnecessary information.

These practices help ensure that the QMS is effective, compliant, and beneficial to the organization.
