Editing BPMN (section)

==Introduction==
The '''Business Process Modeling Notation (BPMN)''' is a standardized graphical notation for drawing business processes in a workflow. BPMN was developed by Business Process Management Initiative ([[BPM#BPMI|BPMI]]), and is now being maintained by the Object Management Group since the two organizations merged in 2005. The intent was to identify the best practices of existing approaches and to combine them into a new, generally accepted language.

Since 2.0 there are 4 '''diagram types''':
* Business Process Diagram (no or only one [[#Pools|pool]])
* Collaboration Diagram (pools and message flows)
* [[#Choreography|Choreography]] Diagram (contains choreography activities)
* Conversation Diagram (message between participants)

A goal for the development of BPMN is that the notation be simple and adoptable by business analysts. Also, there is a potentially conflicting requirement that BPMN provide the power to depict complex business processes and map to BPM execution languages. To help understand how BPMN can manage both requirements, the list of BPMN graphic elements is presented in two groups. First, there is the list of '''core elements''' that will support the requirement of a simple notation. Second, there is the entire list of elements, including the core elements, which will help support requirement of a powerful notation to handle more advanced modeling situations.

If a '''process''' description is detailed enough (including the execution semantics) it is a executable process. A '''public''' process contains only the activities and events which are relevant regarding the messages between partners. It is therefore not executable. The '''private''' process contains all the neccessary details.

===Versions===
The differences betwenn the version 1.0 to 2.0 are described [http://en.wikipedia.org/wiki/Business_Process_Model_and_Notation#Comparison_of_BPMN_versions here]

===Missing Functionalities===
The modeling of the following will not be a part of BPMN:
* Organizational structures and resources
* Functional breakdowns
* Data and information models
* Strategy
* Business Rules
