Abstract: At the beginning of system development system engineering has to ensure that the goals given by the customer will be met at the end of development. All system aspects have to be considered in a coherent manner. Properties and interfaces can be expressed in a manner human beings can understand in case of e.g. mechanical structures or electrical circuits. However, system operations do not have a physical shape. Hence it is difficult to understand what a system will really do before components are integrated and a system is in operation. Therefore the goal of the OMBSIM study [1] was to define an approach (called EaSyVaDe: Early System Validation of Design) for early validation of system operations, i.e. validation at the beginning of a development
