A New Approach for Workflow Process Delta Analysis Based on SYN-NET

Many of today's information systems are driven by explicit process models. Creating a workflow design is a complicated process and typically there are discrepancies between the actual workflow processes and the processes as perceived by the management. Delta analysis aims at improving this by comparing process models obtained by process mining from event logs and predefined ones, to measure business alignment of real behaviour of an information system with the expected behaviour. Syn-net is a new workflow model based on Petri-net, with the conceptual foundation synchronizer and suggesting a three-layer perspective of workflow process. In this paper, we propose a new delta analysis approach based on the reduction rules of Syn-net, to examine the discrepancies between the discovered processes and the predefined ones.
