BPMN Introduction

•What is BPMN ?

•Stands for Business Process Modeling Notation

•Graphical (flow-chart like) notation for capturing business processes and interactions.

•Public standard maintained by OMG; Current version is 1.1

•Vendor neutral

•Business Friendly

•Versatile enough to be used for different levels, starting from a high-level process

description to a detailed process flow for implementation

•Simple enough to be understood by business users yet rich in semantics to be used

•Simple enough to be understood by business users yet rich in semantics to be used

by developers for implementation

•Has capabilities to model non-executable elements or processes

•Execution Ready

•Through a combination of graphical and supporting elements, allows a model to be

populated with sufficient information to generate executable processes.


BPMN 2.0 Highlights

•Extends and addresses BPMN 1.1 Limitations

•No interchange format in 1.1

•2.0 provides visual model and accompanying interchange format.

•No explicit meta model in 1.1

•2.0 provides semantic metamodeland accompanying interchange format.

•No choreography support

•2.0 provides semantic for process interactions and public processes.

•Semantics of modeling constructs not well defined in 1.1.

•2.0 provides refined and formalized BPMN execution semantics.

•In addition, BPMN 2.0 addresses

•Extensibility mechanism for both process model and graphical extensions

•XMI-based and XSD-based interchange formats.

•Refines event composition and correlation

•Data flow and association

•Covers human interactions

•Does not cover

•Organizational models, Data and Information models, Strategy and Rule Models.


BPMN & Processes

•There are different levels of process modeling:

•ProcessMaps–simple flow charts of the activities

•Process Descriptions –flow charts extended with additional

information, but not enough to fully define actual Performance

(abstract process diagrams).

•ProcessModels–flow charts extended with enough

information so that the process can be analyzed, simulated,

and/or executed

and/or executed

•ProcessCollaborations –interaction of processes for fulfilling

a specific Business Function.

BPMN supports defining each of these levels


Basic BPMN 2.0


BPMN Concepts

•BPMN consists of three main objects:

•Activity: Represents work to be done

•Gateway: Controls flow logic of the process. Used for splitting and merging paths.

•Event:Supports asynchronous communication with other processes, error handling,

and controlling flow logic

Activity

Gateway

Event

Sequence Flow BPMN connection object

A Sequence Flow is used to show the order that activities will be performed in a Process.

End Event

Start Event

Sequence Flows


Activity

Task Types

•Task

•Atomic activity. Different types of tasks distinguished by different markers.

•Task Types are:

Rules Task

Service Task

User Task

•Task Types are:

•Service Task (Synchronous system interaction )

•Send and Receive Tasks (Asynchronous system interaction)

•User Task (Human step –managed by workflow engine)

•Manual Task (Not managed by a workflow engine)

•Rules Task (Managed by Business Rules engine)

•Script Task (Used for running scripts)

•None Task (For just documentation and mapping purposes)

•Call Activity (To call another independent BPMN process –Process

chaining)


BPMN by Example -Lanes

Lanes -Provide a visual

means of categorizing

process activities based

on roles.

BPMN by Example –Task types

System steps, Gateways

and Events can go in to

any Lanes.

XOR Data Gateway

•Exclusive conditional split. Represented by or

•One and only one of the paths can be taken based on

conditional evaluation of data on the branches.

•Used for showing multiple alternative paths.

•Good practice to specify a “catch all” default path.

Default Path


Alternative Path

chosen if the

condition based on

data becomes true

BPMN by Example –Exclusive Conditional

Split

Merge

BPMN by Example –Exclusive Merges

Merge without XOR Gateway

Merge with XOR Gateway


XOR Gateway is not a must for merging exclusive

conditional flows.

AND Gateway

•Parallel fork and join. Represented by

•All output paths are taken.

•Parallel paths may be joined downstream by a corresponding

Parallel Gateway or may lead to separate end events.

•Parallel Joins are used for merging unconditional parallel paths

only.


BPMN by Example –Parallel Paths

Other Gateway types-OR Gateway

•Inclusive or “OR” Gateways are Decisions where there is more than

one possible outcome. Represented by

•They are usually followed by a corresponding merging Inclusive

(OR) Gateway.

•Outgoing paths of an Inclusive Gateway can have a default path as

well.


BPMN by Example –Inclusive Split

Inclusive

The following are possible scenarios

(1)Both Approve Quote and Approver

Term

s are executed.

(2)Only Approve Quote is executed.

(3)Only Approve Term

s is executed.


Inclusive

Inclusive Join

Complex Gateway

•Complex Gateways are Decisions where there is more advanced

definitions of behavior can be defined

•Represented by

M out of N sequence flows to arrive before the join is

complete (Voting pattern).

Chained split –The latter

splits are determ

ined by the

evaluation of previous split.


BPMN by Example –Complex split

The following are possible scenarios

(1)Approve Quote is always executed.

(2)Approve Term

s is executed based on

conditional evaluation.


Complex Split

Parallel join

BPMN Loops using XOR Gateway

While loop (Enter Quote Details

executed 1 or more times)

•Loops can be created using an XOR Gateway and by connecting

a Sequence Flow to a previous step (“upstream” object).

•Commonly used for checking conditions and performing redos.

•Synonymous to a while loop and executed 1 or more times.


BPMN by Example -Looping

Loop

Back

BPMN –Embedded Sub-process

•Embedded sub-process denotes a compound activity

(scope)

•Similar to a BPEL scope.

•It can have it’s own Start and End Event but cannot have Lanes.

•Sequential Flows cannot cross embedded sub-process

boundaries.

•It can be collapsed to hide details or expanded to show details.

•It can be collapsed to hide details or expanded to show details.

•You can have embedded sub-process inside another embedded

sub-process. Nesting can be many levels deep.

•Usage

•Used for simplified representation of Processes.

•Embedded sub-process is also used to set the scope of event

handling (More on this later …….)

Call Activity and Re-usable subprocess

•Call Activity is used to call a another BPMN process.

•It is drawn with a thick boundary.

•Call Activity represents the calling element and the child process

is the called element.

•The called element is the Re-usable subprocess or child process.

•When invoking a Re-usable subprocess, it is necessary to pass

instance context from the calling process to called element and


instance context from the calling process to called element and

vice-versa.

•When the Re-usable subprocess completes, control is returned

to the calling process.

•Double-clicking a Call Activity should display the called process.

Why are Reusable subprocesses

important?

•Provide better process modularization and encapsulation

•Provide better reusability

•Provide a better readable process flow

•They provide a way to better adopt TOP-DOWN implementation

strategies

•Promotes multi-owner ship of different parts of the process.

•Promotes multi-owner ship of different parts of the process.

•Used to enforce compliance

•Promote best practices

•Easy enforcement of access privileges.

•Defines Event-handling scope.


BPMN by Example –Reusable subprocess

Call Activity.

Quote to cash –Main Process

Quote Process –Child Process


BPMN –Process Annotation

•Annotations

•Sticky notes (Arbitrary text)

•Can be associated with process or process

steps via Association Flows.

•Are Artifacts and have no defined semantics

Oracle Confidential –Do Not Distribute


•BPM Studio –

Business user friendly process modeling and simulation tool.

BPM Studio now supports BPMN 2.0. BPM Studio has 2

perspectives : (1) Business (2) IT. The IT Perspective is used

to overlay the implementation details on top of the BPMN

process models. Both Business and IT use the same

language and no translation is required.

•Process Composer

BPMN at Design-Time


Process Composer is the new web-based BPMN tooling that

lets business users customize BPMN processes created in

BPM Studio. If the business user changes are restricted to

certain constraints, they can deploy from Composer without

engaging IT.

•BPMN Run-time Engine

The Oracle BPM Suite 11g has a native BPMN 2.0 run-time

engine. Business Processes modeled and implemented in BPM

Studio can be run natively on the BPMN run-time engine.

•BPMN based Monitoring

•Enterprise Manager for BPM –EM allows for rich end-to-end

tracking and monitoring of BPMN processes, including

BPMN at Run-time


tracking and monitoring of BPMN processes, including

exception management.

•Process Portal -Process Portal is a collaborative workspace

built on top of Web Center Spaces and enables more productive

BPM by leveraging collaboration. Includes BPMN view based

process dashboards.

BPM Studio -Process Consistency

Checking

•As a Business Analyst or Developer is modeling a business process,

Oracle BPM Studio will incrementally validate that the process is well

formed and constructed

•Any problems with the process structure will be reported in a visual

fashion on the business process diagram. A problem description and

way to remediate it will be provided when the visual icon is selected.

The strictness of

validation can be

configured.



BPM Studio -Process Documentation

•As a Business Analyst or Developer is

modeling a business process, it will be

required to capture the description of each

process step in the form of documentation.

This documentation will become online

help for the User activities exposed

through the Oracle BPM WorkSpace

•In addition to the process activity,

Business Analysts and Developers can

Business Analysts and Developers can

implement Use Cases providing a

mechanism for these 2 audiences to

communicate specific requirements

•Process Documentation can be localized

to different languages as project

languages are available
