Agenda

● What is BPMN?

● How generate a web application?

● Under the hood

A business process is...● a collection of related, structured activities or

tasks that produce a specific service or product and have to be executed in a specific sequence.

● It often can be visualized with a flowchart as a sequence of activities.

Processes are everywhere...

● Marketing and sales

● Customer relations

● Human resources

● Communications

● Internal policies and procedures

● Manufacturing

● R&D

Business Process Management (BPM) is…

a set of tools and methodologies

to model, automate, monitor and optimize

the processes of an organization

Process lifecycle: continuous improvement

Many applications are process based

● BPM should be everywhere in any type of company

● BUT ….

It is not the case today

Many processes are hard coded

● Because BPM solutions are historically complex to implement and very expensive

➔ So there are exclusively used by wealthiest companies for mission critical projects

● Because it can be tempting to hard code the processes

Agenda

● What is BPMN?

● Under the hood

A Business Process Management System (BPMS) is…

a set of software tools

to implement Business Process Management

in an organization

BPMS● Set of tools to go from Business Process Modeling to

Business Process execution and monitoring.

● Can include extra BPM features such as process simulation, or application generation.

● Helps transforming business logic into something that can be executed

BPMS and agility

● By uncoupling business logic from technical issues, a BPMS brings agility to your business.

● Modify a process =

edit a diagram + redeploy a file

● Improving business processes is transparent for people affected by these processes.

BPMS and continuous improvement

● Open the doors towards monitoring, reporting, business intelligence, simulation...

Agenda

● What is BPMN?

● Under the hood

Business Process Modeling Notation (BPMN) is…

● A standardized graphical notation for modeling business processes

● BPMN 2.0 standard released in January 2011

● proposed by the Object Management Group

● contains standard graphical elements

● uses standard semantics

● identifies standard execution

BPM (for business users)

● BPM answer to questions such as:● “And now, what do I have to do?”

● “How am I expected to do that?”

● “What is going on with the things I was involved in?”

● BPM is all about giving to the end-user the application that exactly reproduce the way he works with those processes on a day to day.

What are the benefits ?

● Business logic is externalized in a process● The BPM solution will manage the life cycle of

the process as well as human and system interactions

● Only link between the web application and the BPM solution is the BPM API

How could we go further ?

BOS Engine

● Bonita execution Engine can be embedded in your applications

● bonita-server and bonita-client are available as Maven artifacts on repositories

● It is distributed under LGPL v2.

BOS Engine

● The engine is basically an API to manipulate processes. (create, instantiate, execute, delete)

● It deals with persistence of process definitions and instances, and with execution of the flow.

● is used for ORM

BOS Engine● BOS Engine can be accessed locally or remotely with

Java, using the same code

Application

bonita-server.jar

Remote

Java Client

bonita-client.jarEJB

HTTP Client(PHP, Python...)

Server

bonita-server.jar HTTP

Bonita Studio

Bonita Studio● Is an Eclipse RCP application. It contains the core of Eclipse,

some other Eclipse projects, and a lot of Bonita specific plugins.

● Relies on Bonita engine for export.● Imports process in BAR(Bonita archive), BPMN 2, XPDL 1

and jBPM 3● Exports process in BAR and BMPN 2

User XP

● Is based on GWT

● Provides a modular UI easy to customize

● Supports BIRT and JasperReports

Process applications

● The studio exports a forms.xml file that describes the form.

● The process application reads this forms.xml build the form model and render it on the page, using GWT.

● The UI can be customized using HTML templates

There is a connector for that...

Agenda

● What is BPMN?

● Under the hood

BOS Engine: the API● ManagementAPI

● Operations related to process installation/removal, resources management.● e.g. deploy(businessArchive), deleteProcess(processUUID), addMetadata(key, value)

● QueryDefinitionAPI● Query operations related to the ‘Definition’ object model.● e.g. getProcesses(), getProcess(processUUID), getProcessActivities(processUUID,

activityName)● RuntimeAPI

● Modification operations related to the ‘Runtime’ object model.● e.g. executeTask(taskUUID), assignTask(taskUUID, userId),

instantiateProcess(processUUID)● QueryRuntimeAPI

● Query operations related to the ‘Runtime’ object model.● e.g. getProcessInstances(), getTaskList(taskState), getVariable(activityInstanceUUID,

variableName)

BOS Engine: the API● RepairAPI

● Advanced administration operations to handle executing process instances that may be off nominal

● e.g. stopExecution(processInstanceUUID, activityName)● CommandAPI

● Operations to execute commands available in a given process or in the overall engine● e.g. execute(command, processUUID), execute(command)

● IdentityAPI● Operations related to the embedded user module● e.g. addUser(userName, password), addRole(roleName), getUsers()

● BAMAPI● Query operations to retrieve statistics from the runtime data● e.g. getNumberOfOverdueSteps(), getNumberOfOpenStepsPerDay(startDate)

Product development -Roadmap & Tracking

● Bonita Open Solution development follows Scrum methodology:

● Sprints & Roadmap● Rigorous usage of a tracker● Backlogs & Burn-down chart

Product development -Continuous Integration

● ~2300 tests for each platform
