The three standards system of quality, environment and occupational safety corresponds to different management responsibilities. According to the organizational structure design of each enterprise, it should be managed by the corresponding responsible department. For example, the quality management system is managed by the quality management department, the environmental protection department is responsible, and the occupational health and safety department or the human resources department is responsible. Generally, this situation is suitable for large enterprises with clear and mature professional division of labor and human resources support.
There are also some enterprises, because there are some commonalities in the management of the three-standard system, so a comprehensive department is appointed to be responsible, and the corresponding responsible department obeys the organizational arrangement of this department to complete specific affairs and management. Generally suitable for small and medium-sized enterprises, with limited human resources and unclear professional division of labor. Large enterprises sometimes consider reducing organizational levels by streamlining personnel, and also adopt centralized management.
