The book "End-User Development" by Volker Wulf provides a comprehensive analysis of the challenges and opportunities arising from the increasing importance of end-user development. In an era where work practices and organizational processes are constantly evolving, it is crucial that the technological infrastructure not only keeps pace with these changes but also actively supports them. The book highlights the limitations of traditional software development approaches, particularly when it comes to meeting the diverse and often unpredictable needs of users. It demonstrates how end-users are capable of configuring, customizing, and further developing software themselves, thereby taking an active role in the development process. EUD is defined as a set of methods, techniques, and tools that enable non-professional software developers to create, modify, or extend software artifacts. Additionally, the social and communicative aspects of end-user development are also examined, including collaboration and exchange among users.
