This study aims to analyse the main benefits observed due to ISO 9001:2015 implementation and certification in Brazilian companies. A survey with market professionals was conducted in order to perform this analysis. The data were statistically treated. First, Cronbach's Alpha was calculated to verify the reliability of the sample and Multidimensional Scaling was performed to eliminate possible outliers. Then, Exploratory Factor Analysis was conducted to identify the variables that englobe most of information variance and allocate them into factors. It was verified that from the 12 variables analysed, 7 were allocated into two factors that explained 70.913% of the model. In Factor 1, the variables were related to improvements in the business processes quality; reduction of errors and defects; improvements in the documentation processes; customer satisfaction. In Factor 2, the variables were related to improvements in cost savings; improvements in market share; and improvements in sales volume. The findings of this research can be useful for both academics and managers, for future research, and to evaluate possible opportunities to combine different managerial approaches to enhance the potential benefits that ISO 9001 can provide, respectively.
