Modeling Process Interactions with Coordination Processes.

With the rise of data-centric process management paradigms, small and interdependent processes, such as artifacts or object lifecycles, form a business process by interacting with each other. To arrive at a meaningful overall business process, these process interactions must be coordinated. One challenge is the proper consideration of one-to-many and many-to-many relations between interacting processes. Other challenges arise from the flexible, concurrent execution of the processes. Relational process structures and semantic relationships have been proposed for tackling these individual challenges. This paper introduces coordination processes, which bring together both relational process structures and semantic relationships, leveraging their features to enable proper coordination support for interdependent, concurrently running processes. Coordination processes contribute an abstracted and concise model for coordinating the highly complex interactions of interrelated processes.
