BPMN (Business Process Modeling and Notation) has emerged as a widely adopted standard for process modeling. Its popularity is based on the fact that it is has been developed by the Object Management Group (OMG), a consortium of organizations that also released other important modeling standards like UML.

The primary goal of BPMN is to provide a notation that is understandable by all users: business analysts designing and documenting business processes, developers implementing these business processes, and business end users executing, managing and monitoring their business processes. Now, the OMG released a new version of BPMN 2.0. This standard shall be supported by ARIS. In a first step, the objective is to focus on process modeling conformance, one of four conformance types defined by the OMG.

The four conformance types are described in detail in the BPMN specification: Business Process Model and Notation (BPMN), version 2.0.
