Numerous software projects fail. This is not only due to the technologies chosen, but often above all to a lack of interdisciplinary communication. Developers and professionals speak different languages and do not understand each other. Golo Roden shows in this workshop how event-driven development not only lays the foundation for better maintainable software, but also reduces the language gap. The participants develop a software from the idea to the finished implementation. This way exactly what the customer really wanted is created.
