Change is an inevitable phenomenon as long as we exist. And it has always been so. Today, changes are happening more and more often and intensely, so we are facing recurring problems, and as we become more and more dependent on other people, other people's problems soon become our problems. Those problems that we do not solve immediately after they arise become potential crises. It is the notion of crisis that is analyzed in detail in this thesis, as well as what causes it. The aim of this paper is to provide an overview of systematic and practical methods of identifying the causes of the crisis that could be related in particular to the public sector. The crisis has a huge impact on the entire organization, which in certain situations can lead to failure. In order to first determine the cause of the crisis, the leaders of the organization affected by the crisis must react quickly to prevent its further development and, if it occurs, to solve it with the least damage. The importance of crisis management is highlighted in this paper, and it forms part of a broader system of organizational management. Based on the analyzed literature and scientific papers, it is easy to assume that there is an unusually low representation of crisis management within Croatian companies, whether public or private. It is the same set of values that these companies possess, starting from ethnic norms of behavior, striving to establish high standards of professionalism and the desire for a solid organizational culture. Even public companies cannot avoid being exposed to market challenges, and depending on the type of work they do, they themselves face crises. The instruments of crisis management and crisis communication methods have not been sufficiently applied in the public sector of the Republic of Croatia, which indicates insufficient preparedness for potential business crises.
