The Integrated Management System (IMS) combines different management systems (e.g., quality, environment, occupational health and safety, information security, energy management, and asset management) into one comprehensive and harmonious management system.
A Quality Management System (QMS) is a set of policies, processes, and procedures necessary for planning and execution (production, development, service) in the core business area of the organization (i.e., areas that may affect the organization's ability to meet customer requirements). ISO 9001:2015 is an example of a quality management system.
An Environmental Management System (EMS) continuously identifies and improves the environmental status and environmental performance of the organization.
An Occupational Health and Safety Management System (or OHSMS) continuously identifies and improves the organization's status and performance in health and safety. This system follows a specific plan and is managed like any other aspect of business.
An Energy Management System continuously identifies and improves energy use and its impact in the organization.
