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 Javastate
transitions
lightweight
embeddable
generic, extensible

XML
BPMN 2.0
OMG standard that definesGraphical notation
Process definition format (XSD / XMI)
Execution semantics
Focus on executable processes
Extensible + Interoperability !

BPMN 2.0 Example
System.out.println("Hello World");
Java Example
// (1) Create a new knowledge base and add process
definitionKnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();kbuilder.add(
ResourceFactory.newClassPathResource("sample.bpmn"),
ResourceType.BPMN2);KnowledgeBase kbase =
kbuilder.newKnowledgeBase();// (2) Create new stateful knowledge
sessionStatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();// (3) Start a new process
instanceksession.startProcess(com.sample.bpmn.hello);

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
