6. 6 From workflows to CBP Notion of business processes received increasing recognition as the ‘glue’ between originally disjoint activities within an enterprise. Business process systems (including workflow management systems) demonstrated applicability within boundaries of enterprise. We envisage that this concept provides a significant opportunity also in the cross-organizational business context. State-of-art focus on workflow models to represent workflows within organisations and were extended to punctually expose communication points to other workflows. Approach breaks the integrative purpose of business processes due to the low-level in process orientation. Goal is to provide a solution that enables modelling and enactment (execution) of CBP (Cross-organisational Business Processes)

8. 8 Framework to support Interoperability for CBP Seller View Process Buyer Process Enterprise Modelling Private Business Process CBP - Collaborative Business Process Execution Interface Buyer Seller CBP Model Process Engine WS Process Enactment Interface Design Formal methods will support integration of private business processes in a coalition whilst maintaining privacy of the participating enterprises Business process execution will trigger Web Services associated to the process, and will monitor their execution. Furthermore, it will provide real-time commands and data harmonisation between WS and has to be supported by infrastructure for message handling, dispatching in a P2P approach. Models are enriched through ontological information and executed by IT systems, e.g. workflow engines

9. 9 CBP Model High-level Requirements 1.Different user groups and modellers are involved in modelling cross- organizational business processes. Their different perspectives and needs have to be reflected in the modelling method  Met by introducing “Process Modelling levels of abstraction” 2.Modelling method allows for selectively hiding internal process steps while offering a mechanism to expose CBP relevant information to partners.  Met by introduction of process views as an additional abstraction layer between the private process and CBP model.  Process views provide a process-oriented interface towards business partners.  Private processes only known to owning organisation and not exposed to others.  Process views are an abstraction of the private processes, containing information that needs to be published for purpose of a specific interaction. Several tasks of a private process can be combined to one view task.

The CBPs modelled on this level are not executable. Detailed view on the CBP representing the complete control flow of the process. Non-executable tasks are replaced by tasks that can be executed in a system. Message exchange between single tasks is modelled, but control flow is specified in a platform independent manner. This supports reuse of process models, as these can be ported to different process engines bellow CBP is modelled in the modelling language of an actual business process engine. It’s extended with platform specific interaction information, e.g. actual message formats sent or received during CBP execution or the specification of particular data sources providing data during process execution.
