Some years ago, change in organisations was seen as a rarely occurring exception. In the past few years, however, the topic has gained increasing importance, becoming a promising field of research. Today, each organisation is faced with different kinds of change. In order to remain a successful player on the global market, organisations need to react and adapt to change immediately. Due to the transformation phenomena the employees and the organisation are confronted with new challenges. As a result of this, the aim of this master thesis is, to find out what the possible causes for the change in the organisations are. Subsequently the challenges for the employees and the organisation as a whole are worked out. In the first chapter there is given a short insight to the topic change and the aim of the master thesis is presented. The second chapter contains a description of change management and the different types of change are described. The conditions for change in organisations are then illustrated on the basis of the 3-W-Model. Furthermore, this chapter focuses on the possible causes for change. Here a differentiation between intern and extern causes is taken. The crisis as one of the causing occurrences of change is also characterized in detail. It also explains why change is already considered a new mode of working and why it has become a permanent task in organisations. The third chapter tries to carve out the correct ratio between stability and change. Two different types of models are descripted in this master thesis, which are used to answer this complex of problems. One of these models is called dynamic-capabilities-projection and the second one is called barrier-determined-option. In the literature there is not only one solution defined as the right solution. In addition, this chapter analyses forecasted trends for the future in the world of work. The fourth chapter then focuses on and describes the main research question in greater detail, followed by an analysis of the challenges occurring as a result of change for the employees and the organisation as a whole. Additionally, this chapter further outlines the impact of these challenges for the employees and the organisation.
