The digital twin is well on the way to becoming an elementary part of the corporate world. Corporate leaders hope that these intelligent images of an increasingly dynamic corporate reality will significantly reduce complexity. Ideally, model-based analyses and (partially) automated decisions using methods of simulation technology and artificial intelligence based on optimized IoT data management can make their contribution to corporate agility. In addition to the definition of terms/concepts, the paper will discuss current challenges and present various examples of their application. Based on these ideas, a process model for the introduction of digital twins in terms of technology migration will be presented.
