All companies strive to find the best way to do business in order to maximize profits and overall satisfaction for all their employees and the community in which they operate. The fact is that every company, regardless of its good business performance over a long period, strategically selected management and high quality and qualified personnel, experiences crisis at least once, and often several times. Crises can be the result of economic changes in the market and inefficient business operations of the company or may be caused by sudden natural disasters. Also, there are crises related to corporate reputation, crises caused by psychopathological behavior, crises related to human resources, physical crises and information crises. The subject of this master thesis is crisis management and understanding of the importance of crisis management and crisis communication. Also, the subject of the research is to identify the causes and symptoms of business crises and crises caused by other causes, and to analyze the actions undertaken by companies after the onset of the crisis in order to remedy the damage. In this master thesis were analyzed companies Agrokor and Croatia Airlines which were affected by business crises, as well as Ikea and Germanwings, which found themselves in crisis situations that affected business. The analysis of the mentioned companies shows the differences, and the causes and consequences, between the economic crisis in the company and other crises that are not a direct consequence of economic activities. Also, as part of the master thesis was made a research on the importance of the role of crisis management in Croatian companies in the context of the crisis.
