CASE MANAGEMENT MODEL AND NOTATION - A SHOWCASE

Abstract

In this paper, differences and similarities of the Business Process Model and Notation (BPMN) and CMMN are revealed. After introducing the visual CMMN elements, ad-hoc and event sub-processes are then introduced as flexible approaches in BPMN. Although many CMMN elements can be substituted by BPMN constructs, the notations pursue different approaches to modeling processes. The findings of the literature review resulted in a model for distinguishing BPMN and CMMN, considering participation of knowledge workers as well as the predictability of the process. While CMMN covers the section of less predictable processes with the active involvement of knowledge workers making decisions and planning during run-time, BPMN is best used for highly predictable work where knowledge workers mainly execute tasks. The results are verified by a case study. The naturalization process of the Swiss canton of Schwyz is translated from BPMN to CMMN to highlight advantages and disadvantages of the new notation. On the basis of the case study, we propose to introduce a visual representation for roles in CMMN as well as to support a case-task element in BPMN to support interaction between the two standards.
