ABSTRACT
LIPOR activity is focused on the waste management (Landfill, sorting plant, energy recovery plant and composting plant) of several municipalities that comprise the greater Porto area (Northern Portugal), notably, Póvoa do Varzim, Vila do Conde, Matosinhos, Maia, Porto, Valongo, Gondomar and Espinho. Yazaki-Saltano produces electrical goods mainly for the automotive industry. The two companies adopted different strategies to proceed with the integration of their MSs into a single IMS. LIPOR has proceeded with the successive implementation of the quality MS (QMS-ISO 9001), the environmental MS (EMS-ISO 14001)
1 INTRODUCTION
1.1 Integrated Management Systems (IMSs)
Standardized Management Systems (MSs) are adopted by companies in order to address more efficiently and systematically the requirements from the stakeholders (Almeida et al., 2014; Domingues et al., 2012). In the early 80 s of the last century, companies were more prone to address the issues raised by the customers and the shareholders. Due to an increasing awareness of the context where companies operate, the notion of stakeholder encompasses today not just the customers and the shareholders but also the employees, the suppliers and the involving society amidst others (Sampaio et al., 2012). To incorporate the requirements from these stakeholders, companies often implement and certify their MSs: according to the ISO 9001 standard to address the requirements of customers, according to the ISO 14001 standard to address the environmental requirements of the society and according the OHSAS 18001 to attend the health and safety requirements from the employees. Currently several companies are managed through an Integrated Management System (IMS) that usually encompasses (but is not restricted to) the quality, environmental and occupational health and safety issues that should be taken into account. Although the existence of some guidelines and frameworks the integration of these MSs into a single system of systems is often developed within each company constrained solely by the resources available. So, it is difficult for the
and the occupational health and safety MS (OHSMS-OHSAS 18001). The ISO/TS 16949 was the primordial subsystem from where the organizational structure of Yazaki-Saltano evolved to an IMS encompassing additionally the EMS (ISO 14001) and the OHSMS (OHSAS 18001). In this latter case, the audit function acted as an integrator concept due to the need to optimize their number and frequency thus avoiding excessive disruptions to the normal production process. A third company from the healthcare sector was contacted but a deeper research on the evolution of the IMS was not possible due to the information access constrains raised by top management.
