A business process is a collection of activities taking one or more kinds of input and creating an output that is of value for the customer [2]. There are various approaches in the field of Business Process Management (BPM) dealing with the analysis, design, configuration, enactment and evaluation of processes [3]. The modeling of the process flows can be realized by means of different languages, e.g. petri nets [4] or the Business Process Modeling Notation (BPMN) [5].
