Agenda● What is BPM? Why is this useful?● What does a BPMS provide?● What is BPMN?● From the process to the application

● What is Bonita Open Solution?● How to model a process?

● How generate a web application?

● Under the hood

● How to develop connectors?

● Use the execution engine's API





● 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


Why ?

●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





● 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...





● 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


BPMN samples

BPMN defines...

● Under the hood




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.


Process based web applications

Process design

Information System Connectivity

Web Application developmentWeb framework

BPM Solution

Software Main steps


How to develop a process based web application ?

BPM Execution Engine

Web Application PageFlow and GUI

BPM API

BPM Interface


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

Local

Application

bonita-server.jar

Remote

Java Client

bonita-client.jar

EJBJAXRS

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





● Under the hood

Connect

There is a connector for that...





● 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)
