Complexity metrics for the Case Management Modeling Notation (CMMN)

Business process management (BPM) is a relative mature discipline with a large number of practitioners. BPM technology is based on directed graphs used to describe control flow. Over the last decade a new way to describe data intensive business processes for knowledge workers have emerged, where the focus is changing from control flow to business data. This emerging process technology is referred in the literature as case handling or case management. The Case management modeling and notation (CMMN) is a new process standard that supports case handling. Complexity metrics have been developed and verified for BPM models based on directed graphs, like the business processes modeling and notation (BPMN). But, CMMN processes are not described by directed graphs. Therefore, complexity metrics developed for BPMN may not be applicable to CMMN. This research plans to fill the gap in the literature by exploring and proposing complexity metrics for CMMN. This will have practical implications for commercial products implementing CMMN.
