Evaluation of the integration level of quality and environmental management systems in a tire manufacturer

Purpose This article aims to evaluate the integration level of a quality management system (QMS) and an environmental management system (EMS) in a tire manufacturer and propose a guide to evaluate the integration of these systems in companies. Design/methodology/approach The methodological strategies used in this research were literature review; and case study, with interviews to verify professionals' perception about benefits from integration. Data from interviews were analyzed through Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Findings The results showed that the studied company has a simple level of integration, observing only some low intensity benefits. Thus, it was recommended that the company partially integrate its management systems (MSs) before evolving into something more complex. The literature and the findings of case study were used as basis for proposing a guide to evaluate MS integration. Originality/value Lessons learned throughout the study and the suggested guide can support other companies to assess the integration level of their QMS and EMS. Thus, the findings presented here can be useful for researchers and managers.
