What is Case Management and Modeling?

Any individual Case may be resolved in a completely ad-hoc manner. As experience grows in resolving similar Cases over time, a set of common practices can be defined for Cases. This becomes the practice of Case Management. Case management requires modeling which can express the essential flexibility that human Case workers require for:

  • run-time planning for the selection of Tasks for a Case,
  • run-time ordering of the sequence in which the Tasks are executed
  • ad-hoc collaboration with other knowledge workers on the Tasks

Case Management Model and Notation (CMMN) is a graphical representation for graphically expressing a Case. 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 and amended by Version 1.1 in December 2016. CMMN is specialized notation to model cases. It is independent from BPMN, and yet they are complementary for each other.
