This Technical Report shows our approach from modeling complex systems using choreographies to making them executable. Two scenarios are used to evaluate the approach. We first model both scenarios in our choreography editor, the BPEL4Chor Designer. The modeled choreography is then transformed into an instance of the choreography language BPEL4Chor. BPEL4Chor itself is not directly executable, so the model is transformed to abstract BPEL, made executable using basic executable completion and finally enriched with non-communication process logic. Furthermore, we analyze the state of implementation of the BPEL4Chor Designer and the components responsible for the different transformation steps.
