A Framework for Automated Reengineering of BPMN Models by Excluding Inefficient Activities

Business Process Reengineering (BPR), originally floated in the early 1990s, is gaining importance in industry and academia. BPR helps the organization rethink their work rationally by redesigning their current processes and resource consumption. Due to the high rate of software evolution, there is a need to run legacy systems on a new computing platform. BPMN models are subject to erroneous or unnecessary activities that are taking too many resources. Such process models are leading to additional cost and effort. Re-engineering help in improving the legacy system or in this context a set of legacy processes to perform better than before. This work presents a framework for automatic reengineering of a BPMN by identifying activities that are taking too much time and resources but are insignificant to the business process. An extensive literature review has led to the extraction of three important parameters based on which the business process activities can be evaluated as necessary or unnecessary i.e. time, resources and priority of an activity. The proposed model has been validated using a case study on the Claim Management System. This work shall be beneficial for the research community and developers targeting construction of a BPR tool
