“…As reported by the authors of the articles (Palacios Guillem, 2019;Santos et al, 2011), the mentioned ISO 9001, ISO 14001 and EMAS systems are the most frequently implemented in SMEs. According to the literature review, it was shown that research in the area of ISO 9001 in SMEs mainly concerned: motivation and benefits from implementation (Khan and Farooquie, 2016;Magodi et al, 2022;Vasilevska and Rivza, 2018;Zimon et al, 2018), main problems occurring during implementation and certification (Unterreiner and Gisbert Soler, 2019), as well as the impact of increasing customer satisfaction with product quality (Usman et al, 2019).
