Processes are only successfully designed when they are understandable to all participants and collectively supported by them. This applies to business processes, organizational workflows, and the development of suitable IT solutions. This book ensures that users, developers, consultants, and management speak the same language to successfully implement business processes. It is crucial that the acting subject is placed at the center. Thus, modeling, visualization, validation, and implementation of processes are equally oriented towards people. Consistent examples and a comprehensive case study ensure a high degree of clarity and practical relevance. Additionally, suitable modeling tools are made available online.
