ISO 9001
International standard for quality management systems with seven principles including process approach and continuous improvement.
ISO 9001 is the international standard specifying requirements for a quality management system (QMS), enabling organizations to demonstrate consistent provision of products and services meeting customer and regulatory requirements. First published in 1987 and revised substantially in 1994, 2000, 2008, and 2015, the current ISO 9001:2015 organizes requirements around seven quality management principles (customer focus, leadership, engagement of people, process approach, improvement, evidence-based decision making, relationship management) and a high-level Annex SL structure shared with other ISO management system standards (ISO/IEC 27001, ISO 14001, ISO 45001) to ease integration. Conformity is demonstrable via third-party certification by accredited bodies and is widely used as a customer or contractual qualification across manufacturing and service sectors.

Primary use case
Third-party certification of organizational quality management systems; supplier qualification and contractual requirement across manufacturing and services; foundation for sector-specific QMS standards (e.g., AS9100, ISO 13485, IATF 16949).
Common criticisms
- Documentation orientation can produce conformance without genuine quality improvement
- certification can become an end in itself rather than a means
- small-business compliance burden
- periodic audit sampling limits assurance depth
- certification body shopping creates uneven rigor across registrars.
