Case Management Model and Notation (CMMN) is a graphical representation for graphically expressing a Case, as well as an interchange format for exchanging Case models among different tools. It is to Case management products what the OMG Business Process Model and Notation (BPMN) specification is to business process management products.

A consortium of 11 companies contributed to the development of CMMN, which is now being maintained by the Object Management Group. Version 1.0 of CMMN was released in May 2014[1] and amended by Version 1.1 in December 2016 [2].
