7. 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

10. Monitoring

12. Speed of development

13. Increased agility

14. Overview of jBPM5

16. targeting developers and business users

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

18. powerful rules and event integration

20. lightweight

21. embeddable

22. generic, extensible Core Engine

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

25. startProcess(processId, parameters)

26. signalEvent(type, event)

27. signalEvent(type, event, instanceId)

28. abortProcessInstance(instanceId)

29. getProcessInstance(instanceId)

30. …

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

32. From Workflow to BPM Core Engine

33. From Workflow to BPM Core Engine BPMN 2.0 XML

35. Notation

37. Process, collaboration, choreography

38. Extensible

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 >

53. runtime binding

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

66. Tooling (IDE, repository, management)

68. Larger scope (reusable)

69. Higher-level

70. Loosely-coupled

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 Rules and Process Integration

78. Example: Clinical DSS

79. Example: Build Management Source: Hudson Execution and Scheduling Architecture

80. Example: Build Management Source: Hudson Execution and Scheduling Architecture

81. Continuum Data-driven Lifetime Stability Granularity Change Dynamic Complexity Declarative User-focused

82. TITLE SLIDE: HEADLINE Presenter name Title, Red Hat Date Demo

85. New Eclipse BPMN2 editor

87. Flexible, adaptive, goal-oriented processes

88. Integrated “no-code” tooling (form builder, etc.)
