An integrated management system (IMS) would means combination of the organization’s various components into one system for easier management and operations. Example Quality, Environmental, and Occupational Health and Safety management systems can be combined and managed as an Integrated Management System, or Quality with Food Safety Management System and so on. Integrated Management Systems is not separate systems that are just joined together, rather they are integrated where similar processes are seamlessly managed and implemented to avoid duplication.
Implementing an integrated management system provides a framework for doing just this. When you integrate your management systems, you reduce duplication and improve efficiency.
