Process Choreographies

This chapter describes the interaction of multiple business processes and, as such, are an important concept for supporting business-to-business collaboration. After introducing high-level choreographies that specify dependencies between interactions of choreographies, service interaction patterns are discussed. Interesting issues occur with regard to the correctness of combined execution when combining multiple business processes. These issues are addressed by discussing the notions of compatibility and consistency. The public-to-private approach is introduced, a concrete technique to develop process orchestrations that are consistent with their behavioural interfaces. This chapter is complemented by introducing language elements of the Business Process Model and Notation that are related to process choreographies.
