A Template-based Approach for Responsibility Management in Executable Business Processes (Summary)


Summary of the Contribution

Process-oriented organisations need to manage the different types of responsi- bilities their employees may have w.r.t. the activities involved in their business processes. Despite several approaches provide support for responsibility modelling, in current Business Process Management Systems (BPMS) the only responsibility considered at run time is the one related to performing the work required for activity completion. Others like accountability or consultation must be implemented by manually adding activities in the executable process model, which is time-consuming and error-prone. This paper addresses this limitation by enabling current BPMS to execute processes in which people with different responsibilities interact to complete the activities. A metamodel based on Responsibility Assignment Matrices (RAM) is designed to model the responsibility assignment for each activity, and a template- based mechanism that automatically transforms such information into BPMN elements is developed. The approach is independent of the platform and hence, the output models can be interpreted and executed by BPMS that support BPMN. Furthermore, the original structure of the process model remains unchanged, as the templates for modelling responsibilities are defined at subprocess level. This provides transparency and does not affect the readability of the original model. As our approach does not enforce any specific behaviour but new templates can be modelled to specify the interaction that best suits the activity requirements, there is high flexibility and generalisability. Moreover, template libraries can be created and reused in different processes. We provide a reference implementation and build a library of templates for a well-known set of responsibilities.
