ISO 9001 is the international standard for quality management systems (QMS) published by the International Organization for Standardization (ISO). It evaluates quality management across the full lifecycle of products and services. With more than one million certificates issued worldwide, organizations of all sizes use it to demonstrate consistent quality. Third-party certification helps build trust and competitiveness and supports long-term growth. The current version is based on HLS (High Level Structure), applying the ISO 9001 : 2015 standard.
