Measuring Method Complexity of the Case Management (CMMN)

Abstract

In 2014, the Object Management Group (OMG) published the Case Management Modeling and Notation (CMMN) ver- sion 1.0 speci cation, which is a new process modeling spec- i cation to complement its Business Process Modeling and Notation (BPMN) speci cation. The declarative nature of CMMN is intended to supplement the procedural perspec- tive of BPMN. CMMN takes a data-centric view to process modeling based on business artifacts to provide exibility for knowledge workers, while retaining the advantages of busi- ness process management (BPM) systems. As far as the researchers are aware, this research is among the rst contributions to the understanding of CMMN's method complexity in the context of other process modeling nota- tions. We used the meta-model-based method complexity approach introduced by Rossi and Brinkkemper to evalu- ate the method complexity of CMMN. The results were compared with other popular process methods, including BPMN, Uni ed Modeling Language (UML) Activity dia- grams, and Event-driven Process Charts (EPC), all of which have undergone similar evaluations by other researchers. The initial results indicated that CMMN 1.0 compares favorably with BPMN 1.2.
