This document was prepared by Technical Committee ISO/TC 176, Quality management and quality assurance, Subcommittee 2, Quality systems.This fourth edition cancels and replaces the third edition (ISO 9004:2009) , which has been technically revised. The main changes compared to the previous edition are as follows: — alignment with the concepts and terminology of ISO 9000:2015 and ISO 9001:2015; — focus on the concept of “quality of an organization”; — focus of the concept of “identity of an organization”. =============== Top management’s focus on the organization’s ability to meet the needs and expectations of customers and other relevant interested parties provides confidence in achieving sustained success. This document addresses the systematic improvement of the organization’s overall performance. It includes the planning, implementation, analysis, evaluation and improvement of an effective and efficient management system. Factors affecting an organization’s success continually emerge, evolve, increase or diminish over the years, and adapting to these changes is important for sustained success. Examples include social responsibility, environmental and cultural factors, in addition to those that might have been previously considered, such as efficiency, quality and agility; taken together, these factors are part of the organization’s context. The ability to achieve sustained success is enhanced by managers at all levels learning about and understanding the organization’s evolving context. Improvement and innovation also support sustained success.
