What is BPM?

8.
What is BPM? A business process is a process that describes the order in which a series of steps need to be executed, using a flow chart. Business Process Management

9.
Why BPM? <ul><li>Visibility

10.
Monitoring

11.
Higher-level </li></ul><ul><li>Continuous improvement

12.
Speed of development

13.
Increased agility </li></ul>

14.
Overview of jBPM5

15.
Key Characteristics of jBPM5 <ul><li>Open-source business process management project offering: </li></ul><ul><ul><li>generic process engine supporting native BPMN 2.0 execution

16.
targeting developers and business users

17.
collaboration, management and monitoring using web-based consoles

18.
powerful rules and event integration </li></ul></ul>

19.
From Workflow to BPM <ul><li>Core engine is a workflow engine in pure Java </li></ul><ul><ul><li>state transitions

20.
lightweight

21.
embeddable

22.
generic, extensible </li></ul></ul>Core Engine

23.
Core Engine Knowledge Base Stateful Knowledge Session Process Definition Process Instance

24.
Java Interface ProcessRuntime interface <ul><li>startProcess(processId)

25.
startProcess(processId, parameters)

26.
signalEvent(type, event)

27.
signalEvent(type, event, instanceId)

28.
abortProcessInstance(instanceId)

29.
getProcessInstance(instanceId)

30.
… </li></ul>

31.
Java Example // (1) Create knowledge base and add process definition KnowledgeBuilder kbuilder = ... kbuilder.add( ..., &quot;sample.bpmn&quot;, 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”);

34.
BPMN 2.0 <ul><li>OMG specification </li><ul><li>Model

35.
Notation

36.
Execution semantics </li></ul><li>Understandable by all business users

37.
Process, collaboration, choreography

38.
Extensible </li></ul>

39.
BPMN 2.0 Example < definitions ... > < process id=&quot;com.sample.bpmn.hello&quot; name=&quot;Hello World&quot; > < startEvent id=&quot;_1&quot; name=&quot;StartProcess&quot; /> < sequenceFlow sourceRef=&quot;_1&quot; targetRef=&quot;_2&quot; /> < scriptTask id=&quot;_2&quot; name=&quot;Hello&quot; > < script >System.out.println(&quot;Hello World&quot;);</ script > </ scriptTask > < sequenceFlow sourceRef=&quot;_2&quot; targetRef=&quot;_3&quot; /> < endEvent id=&quot;_3&quot; name=&quot;EndProcess&quot; /> </ process > </ definitions > < definitions ... > < process id=&quot;com.sample.bpmn.hello&quot; name=&quot;Hello World&quot; > < startEvent id=&quot;_1&quot; name=&quot;StartProcess&quot; /> < sequenceFlow sourceRef=&quot;_1&quot; targetRef=&quot;_2&quot; /> < scriptTask id=&quot;_2&quot; name=&quot;Hello&quot; > < script >System.out.println(&quot;Hello World&quot;);</ script > </ scriptTask > < sequenceFlow sourceRef=&quot;_2&quot; targetRef=&quot;_3&quot; /> < endEvent id=&quot;_3&quot; name=&quot;EndProcess&quot; /> </ process > </ definitions >

52.
Domain-specific Processes <ul><li>Extend palette with domain-specific, declarative service nodes </li></ul><ul><ul><li>define input / output parameters

53.

57.
Flexible Processes

59.
What is flexibility? “ The quality of being adaptable or variable”

60.
Flexibility = Variability + Change

61.
Exceptional Control Flow 90% 5% 3% 2%

62.
Exceptional Control Flow 90% Rule1 When ... Then ... Rule2 When ... Then ... Rule3 When ... Then ... 5% 3% 2%

63.
Processes + Rules + Events

64.
Combining processes and rules <ul><li>Integration </li><ul><li>From loose coupling (decision services)

65.
To advanced integration (process rules) </li></ul><li>Unification </li><ul><li>Rules and processes are different types of business knowledge assets

66.
Tooling (IDE, repository, management) </li></ul></ul>

67.
Decision Service <ul><li>Different life cycle (agility)

68.
Larger scope (reusable)

69.
Higher-level

70.
Loosely-coupled </li></ul>

71.
<ul><li>RuleSet: Evaluating a set of rules in your process (= local decision service)

72.
Process Rules : Data-driven constraints

73.
Triggers : Rules / events start / signal process

74.
Assignment rules

75.
Describing exceptional situations using rules

76.
Modularizing concerns using rules

77.
Using rules to dynamically alter the behavior of the process </li></ul>Rules and Process Integration
