To document processes and procedures in an ISO 9001 compliant QMS, follow these best practices:

1. **Identify and Document Key Processes**: Clearly identify and document the key processes essential for quality management. This includes defining roles, responsibilities, and objectives.

2. **Use a Consistent Structure**: Develop a consistent structure for your documentation, which typically includes the purpose, scope, users, reference documents, process explanation, and records.

3. **Ensure Clarity and Accessibility**: Make sure the documentation is clear and accessible to all employees. It should provide enough information for activities to be carried out as planned without unnecessary details.

4. **Align with ISO 9001 Standards**: Ensure that the documentation aligns with ISO 9001 standards and supports the operation of processes.

5. **Encourage Feedback and Continuous Improvement**: Establish a continuous improvement cycle by encouraging feedback and making necessary adjustments to the documentation.

6. **Engage Leadership**: Engage leadership to drive the QMS and ensure it aligns with business goals.

7. **Regular Monitoring and Audits**: Regularly monitor and measure performance using audits to assess compliance and make improvements.

8. **Document Everything for Traceability**: Document process flows, work instructions, and records to ensure traceability and consistency.

These practices help ensure that the QMS is effective, efficient, and compliant with ISO 9001 requirements.
