The e-training was developed by design thinking practitioners. At the center is a real-life, anonymized project. It shows how a manufacturer of garage doors developed new products and solutions using a design thinking process. In this way the participants get to know the so-called problem space and the solution space in a vivid way. They also learn the three steps that lead through the two spaces. The participants learn what prerequisites must be created in order to apply design thinking. And they will be enabled to carry out their own projects along the design thinking method. In a special chapter, the persona concept is also presented in the context of the practical example.
