Overview
ISO 9001:2015 - Quality management systems - Requirements sets out the criteria for a quality management system (QMS). It applies to any organization, regardless of type or size, that needs to demonstrate consistent delivery of products and services that meet customer and applicable statutory/regulatory requirements and that seeks to enhance customer satisfaction through effective system application, continual improvement and conformity assurance.
The standard emphasizes the process approach, understanding the organization and its context, and risk‑based thinking (actions to address risks and opportunities). ISO 9001:2015 is intentionally generic so it can be integrated with other management systems.
Key topics and requirements
- Context of the organization: identify internal/external factors and the needs of interested parties that affect the QMS.
- Leadership and commitment: top management responsibilities, customer focus and aligning quality policy with strategic direction.
- Planning: set quality objectives and plan actions to address risks and opportunities.
- Support: resources, competence, awareness, infrastructure and documented information (creation, updating and control). The redline content highlights updated documentation requirements and control of records.
- Operation / Product realization: planning and control of processes to deliver products and services, customer-related processes, design and development, purchasing, production/service provision, identification/traceability, and preservation. The standard also covers control of externally provided processes, products and services.
- Performance evaluation: monitoring, measurement, analysis and management review to ensure the QMS is effective.
- Improvement: continual improvement and handling of nonconformities to enhance system performance.
Practical applications
ISO 9001:2015 is used to:
- Ensure consistent product/service quality and regulatory compliance.
