Surveying the effect of implementation of the integrated management system on the performance of employees in PMO1 - Central Headquarter

Nowadays, management systems are used for making targets and guiding organizational activities in many fields in most of organizations. The integrated management system is designed to combine three standards, ISO 9000 (quality management standard), ISO 14000 (environmental management standard), and OHSAS 18000 (Occupational Health and Safety Management), to achieving a comprehensive management system. On the other hand, the efficiency and performance of human resources in organizations as the most important and valuable resource, has the most significant effect on other factors and also, the productivity of the organization. During this research which conducted to survey the effect of the implementation of the integrated management system on the performance of employees in the PMO (Central Headquarter), 178 staff who had bachelor degree or above were questioned; and ultimately by using linear regression and T test, we achieved to this result that implementation of the integrated system had effect on performance of employees in mentioned organization. Using multiple regression results indicate when three variables including quality management system, environmental management system and occupational health and safety management system are surveyed simultaneously, the variable of quality management system has its highest impact and the variable of environmental management system does not have any meaningful effect.
