This thesis explores the application of international standards in business crisis management. Special emphasis is placed on international standards ISO 31000 and NFPA 1600. Thesis highlights the importance of implementing these standard sin order to enhance the resilience of organizations and their efficiency in managing business crises. Still, despite the numerous advantages of implementing international standards, their implementation in Croatia faces challenges such as a lack of awareness about their significance, insufficient resources and limited support from senior management. This research presents and analyzes the structured approach these standards provide, improving both organizational risk identification and response, reducing the likelihood and severity of business crises. Furthermore, it emphasizes, through the analysis of available scientific papers and studies, the need for systematic education and training of managers and employees, investment in internal capacities and also the adaptation of international standards to the local context. Thesis also proposes recommendations for further research, including the analysis of many challenges that Croatian organizations face in the application of international standards, the adaptation of these standards to the local context and the conduction of longitudinal studies to monitor effects over time, and identify best practices. All the insights gained from this research provide valuable perspectives on the benefits, but also the challenges of applying international standards in business crisis management and offer practical guidelines for improving those practices in Croatia.
