This document introduces BPMN 2.0 and how jBPM5 brings its power to business processes. BPMN 2.0 is a standard notation for modeling business processes that is understandable to various roles. It extends BPMN 1.2 with an XML-based notation, execution semantics, extensibility, choreography support, and conformance classes. jBPM5 supports the key BPMN 2.0 elements like activities, gateways, events, and their types, enabling the modeling of complex business processes.

- 2. BPMN 2.0 as the new standard 2
- 3. BPMN 2.0 Specification • Provide a standard notation for modeling business processes that is understandable by – Business Analyst – Technical Developers – Business Managers • Provide the power to depict complex business processes •
- 4. BPMN 2.0 Specification Extends BPMN 1.2 in several areas: • XML-based notation • execution semantics • extensible • choreography • conformance classes
- 6. BPMN2 Categories • Flow elements – Activities – Gateways – Events • Connecting elements • Data • Swimlanes
- 7. Flow Elements - Activities • An activity is a generic term for work that a company performs – atomic or non-atomic (compound) • Types: – Task – Sub-Process • Represented as rounded rectangles
- 8. Tasks • Script Task – Script + language – kcontext variable • User Task – actor(s), group(s), description, comment, ... • Business Rule Task – ruleflow-group
- 9. Tasks • (Custom) Task – taskname – data input / output (literal or mapping) • Service Task – Service (e.g. Java, WS) • Send / Receive Task – Message • Manual Task
- 10. Sub Process • Reusable Sub Process – processId, data input / output • Embedded Sub Process – Collapsed or expanded – variables • Multiple Instance Sub Process – collectionExpression, variableName • Ad-Hoc Sub Process
- 11. Flow Elements - Gateways • Diverging and converging (or mixed) • Diamond shapes • Types – Exclusive – Inclusive – Parallel – Event-based – Complex
- 12. Flow Elements - Events • Something that “happens” during the course of a business process • Represented as circles • Type defined by icon • Catching or throwing • Interupting

BPMN 2.0 <definitions ... > <process id="com.sample.bpmn.hello" name="Hello World" > <startEvent id="_1" name="StartProcess" /> <sequenceFlow sourceRef="_1" targetRef="_2" /> <scriptTask id="_2" name="Hello" > <script>System.out.println("Hello World");</script> </scriptTask> <sequenceFlow sourceRef="_2" targetRef="_3" /> <endEvent id="_3" name="EndProcess" /> </process> </definitions>
- 16. BPMN 2.0 • “Common Executable” subclass + extras • BPMNDI • (Minimal) custom extensions • Extend set of supported constructs over time
