Introduction
This tutorial introduces business process modeling using the BPMN process modeling standard. This session will show how BPMN can support different methodologies as well as different modeling goals (e.g.,orchestration and choreography), using actual business processes as examples. Sample business models will also be presented and explored to illustrate the main concepts and notational innovations. Two short exercises (on paper) will give students the feel of modeling with the major BPMN model elements.

Background

What is Process Modeling?
The capturing of an ordered sequence of business activities and supporting information Business processes describe how a business pursues its objectives There are different levels of process modeling: ProcessMaps – simple flow charts of the activities Process Descriptions – flow charts extended with additional information, but not enough to fully define actual performance Process Models – flow charts extended with enough information so that the process can be analyzed, simulated, and/or executed BPMN supports each of these levels

Background

What isBPMN?
BPMN is flow-chart based notation for defining Business Processes

BPMN is an agreement between multiple modeling tools vendors, who had their own notations, to use a single notation for the benefit of end-user understand and training BPMN provides a mechanism to generate an executable Business Process (BPEL) from the business level notation A Business Process developed by a business analystcan be directly applied to a BPM engine instead of going through human interpretations and translations into other languages

Background

Origins of BPMN
The Business Process Management Institute (BPMI—now a part of the OMG) develops BPML (an XML process execution language) and realizes need for a graphical representation BPML was later replacedby BPEL as the target execution language August, 2001, the Notation Working Group is formed. The group was composed of 35 companies, organizations, or individuals. BPMN 1.0 May, 2004, the BPMN 1.0 specification was released to the public. February, 2006, BPMN 1.0 was adopted as an OMG standard Currently, there are 39 companies that have implementations of BPMN

Background

BPMN Development DriversMust be acceptable and usable by the business community Must be able to generate executable processes (e.g., BPEL) through a BPMN Model (a combination of graphical elements and supporting information (attributes)) Although executable processes triggered the development of BPMN, it was expected that BPMN would be used for more general business purposes BPM is intended to be Methodology AgnosticMethodologies will give guidance as to the purpose and level of detail for modeling BPMN is as complex as it needs to be. Just use what you need…
