The management quality standard is the most widely used standard in the world. The standard’s fundamental principles are:
- Customer focus
- People engagement
- A process approaches
- Evidence-based decision making
- Relationship management with interested parties
Following the ANNEX SL structure, ISO 9001 introduces new concepts, such as risk assessment and satisfaction of the needs and expectations of the interested parties, and it can be combined during its application or certification with other standards that follow the same structure, such as ISO 14001, ISO 45001, ISO 22000, ISO 27001.
