4. Integration of Standardized Management Systems

In this chapter, the authors discuss the specific character of integration between standardized management systems, and the first section considers how such systems might be classified. The authors go on to present the major requirements of the following management system standards: ISO 9001, ISO 14001, ISO 27001, OHSAS 18001 and ISO 22000. This is followed by a description of the concept of integration and its methodology, which is primarily achieved through the presentation of the concept of an integrated system, the reasons for system integration, and strategies and methods of system integration which include the approach based on the PAS standard. Finally, the authors attempt to identify the essence of integration at the stage of system implementation, together with the potential consequences of integration processes.
