Present interaction-centric languages support exception handling in a rudimentary and de�cient way or even ignore this requirements at all. As a consequence a model to specify exceptional properties on a higher level is required which can automate coordinated exception handling out of the conceptual speci�cation. The approach taken in this thesis speci�es exceptional behavior of choreographies on interaction level and describes automated runtime support out of this enhancement. Thereby, the range of issues leading to exceptions and the various way they are handled is identi�ed in a detailed discussion of exception classi�cations and exception handling. Especially regarding modeling issues, it turns out that only expected exceptions can be modeled, while unexpected exceptions need superior solutions. A multi-viewpoint approach dealing with different levels of abstraction is provided with the choreography design process. However, interaction-centric exception classi�cation, handling and modeling on choreography level is marginal targeted. Within this thesis, three interaction notations are identi�ed where interaction exceptions can be applied to: WS-CDL, BPMN2.0 and iBPMN. Out of these notations iBPMN turned out as preferred notation for an extension with interaction exceptions.
