These activities jointly realize a business goal. Each business process is enacted by a single organization, but it may interact with business processes performed by other organizations. 6 Modeling always has a modeling goal Models should only have elements that are relevant for the particular modeling goal Modeling is abstraction, a tion is taking decisions Here: Process Modeling!

2 Process Orchestration Process Choreography 7 A business process management system acts as a central agent that controls the execution of the process activities 8 Enterprises collaborate to achieve their business goals Value chains show B2B or multiparty collaborations (very similar to a conductor centrally controlling the musicians in an orchestra) In a process choreography, independent partners behave as was specified before Interacting Business Processes Choreographies, Modeling Styles 9 10 Connected Behavioral Interfaces Communication activities and their ordering represent behavioral interfaces of the participating processes These activities are connected by message flow Examples: Workflow modules, BPMN Process Diagrams Based on Interactions Interactions, message exchanges, are the atomic steps Relationships between interactions are modeled from a global perspective ibpmn, BPMN Conversation and Choreography diagrams Connecting interfaces might introduce modeling errors 11 communication activity sequence flow 12 incompatible branching structures incompatible sequence flow pool eller Se ller Sel Send auction.
