Eric D. SchabellJBoss Senior Solution Architect

What is BPM?Overview jBPM5Flexible ProcessesCool Stuff

Business Process Managementis a systematic approachto making an organization'sworkflowmore effective, more efficientand more capable ofadaptingto an ever-changingenvironment.

Workflow is?

A business process as an activity or set of activities that will accomplish a specific organizational goal.


From Workflow...

Core engine is a workflow engine in pure Java

state transitions

lightweight

embeddable

generic, extensible

BPMN 2.0

OMG specificationModel

Notation

Execution semantics

Understandable by all business users

Process, collaboration, choreography

Extensible

jBPM5 and BPMN2

Focus on executable processesJava environment

Native execution

SubsetCommon Executable ++

High-level and domain-specific

Minimal custom extensions

BPMN 2.0 Example

System.out.println("Hello World");

BPEL Vs BPMN

Red Hat does not intend to create 2 BPM solutions

BPMN2 is the strategic direction

BPEL requirements will be fulfilled with implementation.

Project Riftsaw implementation of BPEL will be included in SOA-P 5.2

Future BPM solutions will be built on BPMN2 standards

JBoss BPM platform is our answer to all process flow / workflow solutions

JBoss Enteprise BRMS (new in 2009)Enables critical business rules to be managed in a more centralized manner (e.g. Insurance = policy risk assess and pricing; Heathcare = claims processing annual regulatory changes)Avoids need to otherwise re-code business rules redundantly in multiple applicationsLeverages JBoss Rules execution engine which has been available for yearsAdds new browser-based Rules Mgmt app, enabling business users to participate in the review, editing, and maintenance of business rule changesAlso adds Repository to provide version management of multiple sets of business rulesSupports the deployment of business rules to JBoss middleware platforms and non-JBoss runtime environments

Processes + Rules + Events

Combining processes and rules

IntegrationFrom loose coupling (decision services)

To advanced integration (process rules)

UnificationRules and processes are different types of business knowledge assets

Tooling (IDE, repository, management)

Medical process


Web based artifact management

BRM as knowledge repository

BPMN2 processes

Task and process forms

Web designer (Oryx)

Build, deploy, test, manage and collaboration features

That's awesome!

Domain-specific Processes

Extend palette with domain-specific, declarative service nodes

define input / output parameters

runtime binding

Service Repository

[ [ "name" : "JavaNode", "parameters" : [ "class" : new StringDataType(), "method" : new StringDataType(), ], "displayName" : "Java Node", "icon" : "icons/java.gif" ]]

jBPM Eclipse Plugin

Import services from repo

Import default handler

Support for local repo (filesystem)

Support for URI repo
