Business Process Model and Notation

What is it good for?

The main goal of the BPMN language is to erase the communication gap between the business process design and process implementation by providing a graphical notation that all the technical and business users can easily understand.

BPMN 2.0

From the version 2.0+ the language contains also the execution semantics for all BPMN elements and defines a mechanism for extending standard elements with custom attributes.
