Todays companies are subject to perpetual change as market requirements vary from day to day. Furthermore, changes in companies are increasing due to economic crises. They may have a huge impact on the companies daily business, so in extreme cases it is very hard for them to survive. From an economic point of view, an economic slowdown also has ramifications for businesses and people that are in a relationship with the affected companies. People that belong to the affected companies as well as external persons both have to live with the consequences that arise from such crises. Therefore, it is of significant advantage to identify crises affecting companies in a timely manner. Moreover, it is in the interest of all involved parties to introduce appropriate countermeasures. The aim of this thesis is to investigate the formation process of these crises. In this study, investigations are based on both theoretical and practical aspects. The reasons for crises and their distinctive features are analysed as a first step. In a second step, the communication channels used for transmitting public information are dissected. Consolidated financial statements and the management reports can be analysed in order to obtain more information to help assess if companies tend to enter crises. In part of this thesis, the most important key performance indicators are shown and described in detail. In order to strengthen the theoretical fundamentals, an examination of the wealth of the Volkswagen Corporation is performed. This is of particular interest as Volkswagen is currently struggling with a crisis. It is shown, at which point in time it became possible to identify the crisis. Furthermore, the progress of the crisis and its impact on the companies wealth are revealed. Last but not least, the challenges that came up during the investigations are discussed in some detail.
