Key Characteristics of BPM
Visibility
Monitoring
Higher-level
Continuous improvement
Speed of development
Increased agility
A business process is a process that describes the order in which a series of steps need to be executed, using a flow chart.

Key Characteristics of jBPM5
Open-source business process management project offering:
generic process engine supporting native BPMN 2.0 execution
targeting developers and business users
collaboration, management and monitoring using web-based consoles
powerfull rules and event integration

From Workflow to BPM
Core engine is a workflow engine in pure Java
state transitions
lightweight
embeddable
generic, extensible
Core Engine

Core Engine Knowledge Base Stateful Knowledge Session Process Definition Process Instance

From Workflow to BPM Core Engine

From Workflow to BPM BPMN 2.0 XML Core Engine

BPMN 2.0
OMG standard that defines
Graphical notation
Process definition format (XSD / XMI)
Execution semantics
Focus on executable processes
Extensible + Interoperability !
http://www.omg.org/spec/BPMN/2.0/

BPMN 2.0 Example < 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 >

Java Example // (1) Create a new knowledge base and add process definition KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add( ResourceFactory.newClassPathResource("sample.bpmn"), ResourceType.BPMN2); KnowledgeBase kbase = kbuilder.newKnowledgeBase(); // (2) Create new stateful knowledge session StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); // (3) Start a new process instance ksession.startProcess(“com.sample.bpmn.hello”);

Domain-specific Processes
Extend palette with domain-specific, declarative service nodes
define input / output parameters
runtime binding

Human task service
User task
Human task service (WS-HT)
Task lists
Task life cycle
Task clients
Task forms

Ready for the future?
Traditional systems have problems with change, complexity, flexibility, data-intensive applications, etc.
Adaptive Case Management (ACM)
Unstructured or non-lineair processes
Event-driven BPM (edBPM)

Processes + Rules + Events

Unstructured processes
