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. **Train Employees**: Train employees on the documented procedures to ensure alignment with ISO 9001 standards.

5. **Monitor and Measure Performance**: Regularly monitor and measure performance using audits to assess compliance.

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

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

8. **Document Everything**: Ensure all process flows, work instructions, and records are documented to maintain traceability and consistency.

These practices help ensure that the QMS is effective and compliant with ISO 9001 standards.
