ISO 9000:2015 — Quality management systems — Fundamentals and vocabulary. This International Standard defines the fundamental concepts, principles and vocabulary used across the ISO 9000 family of quality management standards and provides the common language necessary for implementing, understanding and auditing quality management systems (QMS).

Abstract

ISO 9000:2015 establishes the essential concepts and terminology for quality management systems. It explains the underlying principles of quality management, clarifies key terms used throughout the ISO 9000 family (including ISO 9001), and supports consistent interpretation of requirements, guidance and conformity assessment. The 2015 edition emphasizes process approach, risk-based thinking, and the context of the organization while updating vocabulary to cover products and services and modern management practices.

Scope

This standard specifies the terms and definitions that apply to all quality management and quality management system standards developed by ISO/TC 176. It describes the fundamental concepts and principles of quality management that are universally applicable to organizations of any size, type or sector. ISO 9000 is intended to be used as a reference to ensure consistent interpretation of the vocabulary and concepts used in ISO 9001 and related QMS documents; it does not contain certification requirements.

Key topics and requirements

• Definitions of key terms used in quality management (e.g., quality, conformity, nonconformity, product, service, interested party).
• Fundamental concepts and seven quality management principles that underpin the ISO 9000 family.
• Explanation of the process approach and how processes interact within a QMS.
• Risk-based thinking as an integral part of planning and operation.
• Context of the organization and identification of interested parties and their requirements.
• Documented information (replacing older 'documents' and 'records' terminology) and related controls.
• Continual improvement, performance evaluation and relationship management.
• Guidance to support consistent interpretation of ISO 9001 requirements (note: ISO 9000 itself is not a certifiable standard).

Typical use and users

ISO 9000:2015 is used by organizations preparing for ISO 9001 implementation or certification, by auditors and certification bodies for consistent interpretation, and by trainers, consultants and educators as the definitive vocabulary and conceptual foundation for quality management. It is also referenced by standards developers, regulators and supply chain partners to ensure common understanding across industries and borders.

Related standards

Key related standards include ISO 9001 (requirements for quality management systems), ISO 9004 (guidance for sustained success), ISO 19011 (guidance on auditing management systems), and a range of ISO 10000-series guidance documents on customer satisfaction and related processes. ISO 9000 provides the conceptual and terminological foundation for the entire ISO 9000 family.
