The current invention relates to a technology for processing of compensation scopes comprised within atomic scopes of a process model by a Workflow Management System or a computer system with comparable functionality (WFMS). The method comprises a step of checking whether the atomic scope of the process instance of that process model has been aborted abnormally. If this is the case, in a further step it is analyzed if in the process model the compensation scope has been associated with a specific atomic scope behavior specification, defining a specific abort handling for the compensation scope in the particular case that the compensation scope is comprised within an atomic scope and the atomic scope has been aborted. In a final step the compensation scope is processed according to the specific atomic scope behavior specification.

Transactions within a process model are determined by grouping a set of individual process activities into a single transaction. This effectively reduces the processing overhead, and, therefore, improves the overall throughput and latency of the execution of the process model. The transaction is determined by performing an optimization procedure that takes into account the structure of the process model as well as various properties of the single process activities of the process model. Analysis of the properties of the process activities as well as application of the optimization procedure is performed dynamically during execution of the process model by a workflow engine.
