NOTE 1 Management system: set of interrelated or interacting elements of an organization to establish policies and objectives and processes to achieve those objectives. A mana

23、gement system can address a single discipline or several disciplines (e.g. quality, environment, occupational health and safety, energy, financial management). The system elements include the organizations structure, roles and responsibilities, planning and operation, performance evaluation and impr

24、ovement. The scope of a management system can include the whole of the organization, specific and identified functions of the organization, specific and identified sections of the organization, or one or more functions across a group of organizations.
