Abstract
Case Management Model and Notation (CMMN) is a graphical notation used to model less predictable, highly flexible processes that may behave differently in each instance. It uses an event-centred approach and expands on what can be modelled with procedural modelling notations. Nearly a decade since the occurrence of CMMN, its practical use is questionable. We performed this research to identify possible reasons for this and to classify potential advantages and disadvantages of CMMN. With the aforementioned objectives, our research method was a systematic literature review, which provided a broad insight into the state of the investigated object along with techniques for analysing qualitative data, coding and successive approximation. From an initial set of 942 articles, 43 remain relevant. The results of the analysis and synthesis of the obtained data from relevant articles were generalised codes, which were used to explicitly answer the research questions. Results indicate that CMMN has good foundations in the declarative modelling approach and within the Case Management paradigm. Nevertheless, some issues were identified with notation and elements of CMMN and with its complement - Business Process Model and Notation (BPMN).
