Bpmn 2.0

AbstractThe Business Process Model and Notation 2.0 (BPMN) standard has been hailed as a major step in business process modeling and automation. Recently, it has also been accepted as an ISO standard. The expectation is that vendors of business process management systems (BPMS) will switch to the new standard and natively support its execution in process engines.This paper presents an analysis of the current state and evolution of BPMN2.0 support and implementation. We investigate how BPMN2.0 implementers deal with the standard, showing that native BPMN2.0 execution is an exception. Only three out of 47 BPMS considered support the execution format defined in the standard, although all of them claim to comply to the BPMN2.0 standard. Furthermore, we evaluate three process engines that do provide native BPMN support, namely camunda BPM, jBPM and activiti, and examine the evolution of their degree of support over a period of more than three years. This lets us delimit the areas of the standard that are considered important by the implementers. Since there is only a limited increase in supported features over the past years, it seems that the implementation of the standard is more or less concluded from the perspective of the implementers. Hence, it is unlikely that features which are not available by now will be implemented in the future. Only three out of 47 vendor implementations of BPMN do support the direct execution of the native BPMN format.These three implementations only support around half of the features of BPMN.The feature support is sufficient to implement at least 13 out of 20 workflow control-flow patterns.Erroneous process models are often not rejected at deployment.There is only a limited increase in feature support over the last four years.
