The aim of the project is to research the evolution of the concept of agility. Started mainly as project management methodology, in particular in IT development projects, the concept has experienced a strong push in recent years into other areas even beyond business like for example politics. During this process the concept and particular its use and related practices have experienced a significant broadening. Addressing this, the project firstly aims at identifying and analysing the different roots of the agile concept and its methods/practices and tools, which existed even before its emergence in IT development during the 1990s. Secondly, the subsequent development of the key concept as well as their practices and tools should be explored. In particular it is of interest how the different methodologies became of importance in project management and how they related to each other. This also include its interrelations and interdependencies with other trends such as f. e. digitalization. Finally, it should be analysed how the concept emerged from the IT domain again and entered other areas of application in business as well as in society. The overall aim is to generate insights into the conceptualisation of agility, the practices of it including methodologies and tools as well how it relates to other contemporary develepmonts.
