by Kris Verlaenen The future of (j)BPM

Overview
Short introduction to BPM
jBPM5
Key Features
BPMN2
Architecture
Roadmap
Adaptive processes

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.

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

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

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 ...

Roadmap
Adaptive processes

2005 jBPM3 RuleFlow jBPM4 jBPM5 2011 Drools Flow 2009 2008 Best of both worlds !

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

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 >

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

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

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

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

Customizable

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

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)

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

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

Adaptive Processes
Traditional workflow management systems have problems with
Change
Complexity
Flexibility
Data-based
!!! HOT !!!

Do we want this?

Agility = Variability + Change

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

Non-lineair processes

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
