“…From the moment ISO 9001 faced the light of the day, until nowadays, scientists and professionals argue if QMS (designed according to ISO 9001) would bring any benefits to organizations and what would those benefits be. There are numerous studies conducted on this topic, some of them evidencing benefits brought to company by QMS (Shaikh and Sohu, 2020;Tar ı et al, 2017;Duh et al, 2012;Lee, 2012;Lee et al, 2009;Molina-Azorı n et al, 2009;Tarı' et al, 2014;Yunis et al, 2013), while there are other authors stating that benefits of ISO 9001 implementation are just a myth (Djofack and Camacho, 2017;Murmura and Bravi, 2017;Abaker, 2016;Taouab, 2016;Prajogo and Han, 2012;Lo et al, 2011;Yeung et al, 2006). Some studies prove that ISO 9001 implementation brings disadvantages to companies (Bekele and Zewedie, 2017;Prajogo and Han, 2012;Tar ı et al, 2012;van der Wiele and Brown, 1997;Casades and Karapetrovic, 2005;Singh et al, 2006;Chen and Paulraj, 2004;Heikkil€ a, 2002;Wisner and Tan, 2000) as well, although these studies are much less represented in scientific opus and are based predominantly on employees' opinions rather than on evidences.…”
