A presentation of the future of jBPM.

1. by Kris Verlaenen
The future of
(j)BPM

2. 2
Overview
● Short introduction to BPM
● jBPM5
– Key Features
– BPMN2
– Architecture
– Roadmap
● Adaptive processes

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

5. Palette
Predefined set of generic node types
– Start, end
– Gateway
– Script
– Sub-process
– Event
– ...

6. Business Process
Management
● BPM is a discipline
– Many actors
– Entire life cycle
● We focus on executable processes
● Core engine = key component

7. BPM Advantages
● Visibility and transparency
● Monitoring
● Higher-level (involve business analysts)
● Automation, continuous improvement
● Increased speed of development
● Increased agility (change process more easily)
● and many more ...

Key Characteristics
● Business process engine
– using BPMN2 standard (native execution)
– lightweight, embeddable
– generic process engine
● Full life cycle support
● Higher-level, domain-specific processes
● Powerful business rules and event processing
integration

11. 11
BPMN 2.0
● OMG standard that defines
– Graphical notation
– Process definition format (XSD / XMI)
– Execution semantics
● Extensible
● Interoperability !
● http://www.omg.org/spec/BPMN/2.0/

BPMN 2.0
<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>

13. 13
Standard-based
● BPMN 2.0
● WS-HumanTasks
● JPA
● JTA
● JMX
● ...

14. 14
Generic Process Engine
● Generic features
– Persistence
– Transactions
– Timers
– Expression dialects
– Multi-threading
– Events
– Commands + interceptors
– Session management

15. Domain-specific processes
● Extend palette with domain-specific, declarative
work items
– define input / output parameters
– runtime binding

16. 16
Domain-specific processes
● Other examples
– Email / notifications
– File management: archive, find, copy
– FTP, RSS, Jabber, Rest
– ESB
– Google Calendar, social websites
● Library

● What happened / is happening ?
● Query
● Customizable

23. 23
Eclipse Tooling
● Developer-oriented
● Features
– Graphical BPMN2 designer
– Wizards
– Runtime (classpath container)
– Validation / errors
– Debugging
– Repository synchronization

26. 26
Web Tooling
More business or end-user oriented
● Process management console
● Human task console
● Reporting / BAM console
● Repository console
● Web-based BPMN2 process editor (Signavio)

32. 32
jBPM5 Roadmap
● Currently under community review
● More details soon !
● jBPM 5.0
– Focus on core components
– Near the end of the year
– Productization approximately 6 months later
● Regular (2-3 month) releases after that

33. 33
Migration
● Migration process from jBPM 3 or 4
– One-shot migration process
– Process definition
● Transform jPDL to BPMN2
● Semi-automatic
– API
– Documentation
– No runtime data migration

Adaptive Processes
● Traditional workflow management systems
have problems with
– Change
– Complexity
– Flexibility
– Data-based

Do we want this?

37. 37
Agility
=
Variability
+
Change

38. 38
How?
● Decision service to externalize decision logic as
business rules
● Process improvement
– Migration of running instances
● Unanticipated work
● Unstructure processes
● Processes, rules and events working together

39. 39
Non-lineair processes

40. 40
Processes + Rules + Events
A business solution usually involves the interaction
between these technologies.
● Technology overlap
● Business overlap
Several (good) products on the market, better either at
rule or business process or event processing
Attribute the same importance to the three
complementary business modeling techniques
