this presentation is about Business process modeling notations and how to use them.

1. Introduction to
BPMN

2. Agenda
• What BPMN Is and what it is not.
• What is Business Process ?
• BPMN Essentials
– BPMN Activity
– BPMN Events
– Gateways
– Connectors
• Orchestration and Choreography

3. What BPMN is?
• BPMN is…
• A Graphical modelling language, with symbols,
relationships and attributes for
• Expression of processes generated into
executable processes (BPEL)
• Expression of processes for ‘general execution’
(Human, human-operated)
• Simple, palatable language – ‘flowchart-like’ non-
IT practitioner consumption

4. What BPMN is not?
• BPMN is not…
• A methodology, process, framework
• Complex, usable in subsets

5. What BPMN is not?
• Business Processes – description of how a
business pursues its objectives
– Process Maps: simple flow charts of high-level activities
– Process Descriptions: flow charts with more information
(not enough for full realization)
– Process Model: flow charts with enough information for
analysis, simulation, execution
– BPMN is flexible to handle all variants of BP

6. BPMN Essentials:
• Logical process ‘flow’, finite start and end
points
• Diamond – decision point? yes/no paths for
an extra step
• Rounded boxes must therefore ‘do stuff’

8. BPMN Activity
• Work performed within a
business process

9. BPMN Events
• Start Events

10. BPMN Events
• Intermediate Events
• End events

11. Gateways
Gateways are modeling elements
that
are used to control how Sequence
Flows interact as they converge and
diverge within a Process

12. Connectors
1-A Sequence Flow is used
to show the order that
activities will be performed
in a Process
2- A Message Flow is used to
show the flow of messages
between two entities that
are prepared to send and
receive them
3- An Association is used to
associate data, information
and artifacts with flow
objects

13. Swimlanes
• Pools
• Lanes

14. Orchestration and Choreography
• Orchestration
– Contained within one Pool
• Choreography
– Defined by the interaction between Pools
