“…The results of the study reveal that ISO 9001 certification positively impacts customer satisfaction, customer retention, market share, employee productivity and employee satisfaction (similar results were reached by Gotzamani, 2010;Karapetrovic, Casadesus and Saizarbitoria, 2010;Nabavi, Azizi and Faezipour, 2014;Melão and Guia, 2015;Valmohammadi and Kalantari, 2015;-bekele and Zewedie, 2017;Husseini et al, 2018;Kakouris and Sfakianaki, 2018;Othman, 2019;Sweis et al, 2019), but there is no evidence of its impact on employee retention. Some of the authors finding positive impact of ISO 9001 on employee satisfaction (Rodríguez-Antón and Alonso-Almeida, 2011; Sakka, 2013;Bekele and Zewedie, 2017;Neyestani and Juanzon, 2017;Sweiss et al, 2019) explain that such effect comes from improved education, communication, empowerment, team work, clear quality goals, continuous improvement and improved working conditions, especially regarding safety and health at work. Positive impact of certification on customer-related company performance supports the assumption that ISO 9001 certificate helps companies to obtain legitimacy in their institutional environment, improve image and overcome trade barriers.…”
