In order to meet the demands of the environment, organizations usually implement a range of management systems. However, difficulties related to the parallel management of these systems may arise, and the companies are then driven to integrate their management systems into a single Integrated Management System (IMS). Given this scenario, researchers have designed models to ease the implementation of an IMS and the integration of documents and have investigated the benefits and difficulties of such an implementation. However, these studies have not shown how the integration of management systems takes place in organizations; therefore, the investigation of this process seems to be an interesting area to study contributing to IMS research. Focusing on the normalized management systems ISO 9001 and OHSAS 18001, this paper analyzes their integration by means of a case study based on three variables: IMS implementation process, integration of the IMS management norm requirements and structure. The results show similarities between the IMS implementation process and the documentation related to the IMS established by the organizations. It was also found that the size of the organization can affect the structure established to oversee the IMS management.
