Flexible Workflows at Design- and Runtime Using BPMN2 Adaptation Patterns

Flexible workflow management systems facilitate the adaptation of workflows to changing data contexts. They are however usually not aligned with industry standards and often entail the peril of uncontrolled execution variant growth. Therefore we present a novel approach relying on BPMN2 and business rules for workflow adaptation at designand runtime. For the specification of structural adaptations, we consolidate change-, exception- and time-patterns into one BPMN2 pattern catalogue as the main contribution of this paper.
