Since 1994, the ISO 9001 standard has been the pillar on which the majority of management system standards are based. Oriented towards quality and centered on customer satisfaction, the ISO 9001 standard has not ceased to evolve over the years from the implementation of the process approach to integrating the notion of analysis of the economic context into which the company lives. The establishment of a quality management system according to the ISO 9001 standard, allows all types of companies (whether in the industrial sector, service, commercial, public company, etc.) to lay the foundation a management system for the latter which makes it possible to identify the needs and expectations, both of customers and of other interested parties, and to set up processes which make it possible to meet these needs and expectations. Since the 2015 version, the structure of the ISO 9001 standard forms the backbone of all management system standards, such as Food Safety, Environment, Occupational Health & Safety, etc.
