2. Overview <ul><li>What is BPM?

3. Overview of jBPM5

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

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( ..., "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

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="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 > < 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 >

40. From Workflow to BPM Core Engine BPMN 2.0 XML Persistence Trans- actions JPA JTA

41. Persistence and Transactions <ul><li>Persistence (JPA, pluggable) </li><ul><li>Runtime persistence

42. History logging

43. Services </li></ul><li>Transactions (JTA, pluggable) </li><ul><li>Command-scoped

44. User-defined </li></ul></ul>

45. From Workflow to BPM Core Engine BPMN 2.0 XML Persistence Trans- actions Events History Log Management Console BAM

46. Console <ul><li>Web-based management

47. Business user

48. Features </li></ul><ul><ul><li>Process instance management

49. User task lists / forms

50. Reporting </li></ul></ul>

51. From Workflow to BPM Core Engine BPMN 2.0 XML Persistence Trans- actions Events Integration Domain-specific Processes Human Task Service ESB

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

53. runtime binding </li></ul></ul>

54. Human task service <ul><li>User task

55. Human task service (WS-HT) </li></ul><ul><ul><li>Task lists

56. Task life cycle </li></ul></ul><ul><li>Task clients </li></ul><ul><ul><li>Task forms </li></ul></ul>

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

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

83. Roadmap <ul><li>jBPM 5.0: Februari 2011

84. jBPM 5.1: NOW ... </li><ul><li>Improve designer to support full round-tripping

85. New Eclipse BPMN2 editor

86. Lots of small feature improvements and bug fixes </li></ul><li>jBPM 5.2 – jBPM 6.x </li><ul><li>Simulation / testing / replay

87. Flexible, adaptive, goal-oriented processes

88. Integrated “no-code” tooling (form builder, etc.) </li></ul></ul>
