Instrument for evaluating IMS and sustainable performance

Purpose The number of standards for management systems (MSs) has increased recently. Among the most recognizable ones are ISO9001, ISO14001 and OHSAS18001. The need for integration has risen due to the development and adoption of more than one MS in the same business, in a process known as integrated management systems (IMS). Some authors have argued that the use of IMS contributes toward sustainability. The purpose of this paper is to present an instrument to assess the integration of different MSs and its effect on sustainable performance. Design/methodology/approach A review of IMS, maturity of IMS and sustainability was conducted to build the instrument used in this research. Domingues et al. (2016), Poltronieri et al. (2017), Bernardo et al. (2009) and ISO9001:2015 were used as references pertaining to IMS, whereas Global Reporting Initiative and the research of Delai and Takahashi (2011) were employed for performance issues. All were evaluated both qualitatively and quantitatively. Findings In the pre-test the order of some questions was changed, some other questions were reformulated and a new classification was created. The evaluation of specialists contributed to reduce the number of questions and make the questionnaire more clear. Cronbach’s α was used to prove the reliability of the questionnaire. Originality/value The importance of this study lies in the development of an instrument that helps assess the maturity of the integration of MSs and evaluate sustainable performance.
