Workflow patterns put into context

In his paper ??Approaches to Modeling Business Processes. A Critical Analysis of BPMN, Workflow Patterns and YAWL??, Egon B?rger criticizes the work of the Workflow Patterns Initiative in a rather provocative manner. Although the workflow patterns and YAWL are well established and frequently used, B?rger seems to misunderstand the goals and contributions of the Workflow Patterns Initiative. Therefore, we put the workflow patterns and YAWL in their historic context. Moreover, we address some of the criticism of B?rger by pointing out the real purpose of the workflow patterns and their relationship to formal languages (Petri nets) and real-life WFM/BPM systems.
