Agenda


What is a business process

• Sequence of activities performed by one or more business participants in order to deliver value to the business

• Can be represented as a workflow


Business Process as a Workflow


Business Process Management

• BPM is a means to study, identify, change, and monitor business processes

• BPM is not about technology• BPM is not about creating diagrams• BPM is about improving business



• BPM is a means to study, identify, change, and monitor business processes

• BPM is not about technology• BPM is not about creating diagrams• BPM is about improving business


A pin factory Булавочная фабрика

• Adam Smith’s pin assembly process from the Wealth of Nations (1776)



• Management discipline• Software engineering

BPM as a Management Discipline

• Analysing your business processes• Documenting your business

processes• Optimizing your business processes• Make the organization more efficient


What is required for BPMAAMD

• Tools–Whiteboard–Word– Excel– Napkins!

• Process modeling– BPMN


BPM as a Software Engineering Discipline

• Tools to draw execution flows• Decorate diagrams with technical

details• Execute processes on a BPM platform


What is required for BPMAASED

• Runtime engine (e.g. Oracle Workflow or Activiti)– Executable process at input– Coordinates execution– Keeps track of state– Advanced state machine

Agenda


What is BPMN?

• Business Process Model and Notation• Graphical representation of a

business process


Why BPMN?

• Standardized– ISO standard for process modeling

• Interchangeable– Easy to switch between IT products

• Executable– Automation improves process efficiency

and consistency

• Serializable– Can be converted to XML


Why BPMN?

• Human-oriented– Contrast with BPEL, which is machine-

oriented

• Bridge for the gap between process design and process implementation


BPMN example


BPMN 2.0 Constructs

• Set of elements plus rules used for representing a business process model– Events– Sequence Flow– Gateway– Tasks– Sub-processes– Transactions


Events

• Model something that happens during a lifetime of a process

• Visualized as a Circle


Start Event

End Event Timer Event

Error Event

Gateways

• Control the flow of execution (if, else)• Visualized as a diamond shape,

with an icon inside (gateway type)

X O +Exclusive

Inclusive Parallel


Exclusive Gateway

• Model a decision in a process• Follows a single outbound path

X

Parallel Gateway

• Model concurrency in a process• Follows multiple outbound path

+

Inclusive Gateway

• Combines the exclusive and parallel gateway


O

Tasks

• Action that occurs in a process– Send an e-mail– Call a Web Service in Java– Request work to be done by a human

• Visualized as a rounded rectangle


User Task

Script TaskService Task

Loop Task

Sub-processes

• Activity that contain other activities– Allows hierarchical modeling– Creates a new scope for events

Signature Task

• Signature is a task for interacting with people, who are asked to approve or reject an electronic document

• Custom version of a BPMN User Task


Workflow Engine

• We use Activiti, a BPMN 2.0 platform

• BPM for Business and IT people• Written in Java• Open-source
