1. Business Process Modeling Notation (BPMN)

2. Standardized Notation for describing business processes (workflows)
What is it?
Standardized Notation for describing business processes (workflows)
Understandable by all Process Analysts
Easy to use
Understandable by Developers
Compatible with process implementation applications

3. The Business Analyst will document Workflows for several reasons
When is it used?
The Business Analyst will document Workflows for several reasons
Understanding current processes
Identification of productivity gains
Describe the proposed process or changes
Support creation of the business domain model

4. Workflows can be detailed from different prospectives
Variations
Workflows can be detailed from different prospectives
Workflow using current automation
Workflow as if no automation existed (a true business workflow)
Choose the prospective appropriate for reason in creating it

5. Workflow Diagrams are made up of standard symbol “Elements”:
Basics
Workflow Diagrams are made up of standard symbol “Elements”:
Flow Objects
Connecting Objects
Swimlanes
Artifacts

6. There are three kinds of Flow Objects
Events
Activities
Gateways

7. Flow Objects
Events
Activities
Gateways

8. Simple Workflow
Do Activity
Done?
Yes No

9. Events are things that “happen” They can trigger an activity to occur
Flow Objects - Events
Events are things that “happen”
They can trigger an activity to occur
Ex: “Start Class Registration”
They can be the result of an activity
Ex: “Registration Completed”

10. Flow Objects – Activities
Activities are the “work” to be performed
Examples:
Enter Student Name
Review Curriculum
Choose Classes
Attend Classes
Take Tests

11. Flow Objects – Gateways
Gateways “control” the divergence and convergence in sequence of activities
Examples:
Is Student Registered?
Is Class Available?
Has Student completed pre-requisites?
Has Student paid?

12. There are three kinds of Connecting Objects
Sequence Flow
Message Flow
Association

13. Connecting Objects
Sequence Flow
Message Flow
Association

14. There are two kinds of Swimlanes
Swimlane Objects
There are two kinds of Swimlanes
Pools
Lanes

15. Swim Lanes Pool Lanes No Do Activity Done? Yes No Do Activity Done?

16. There are three kinds of Artifacts
Data Object
Group
Annotation

17. Artifacts
Data Object
Group
Annotation

18. Workflow Diagrams
Elements can be combined to create workflow diagrams
These elements have been used for Business Process Modeling over 30 years

19. Introducing BPMN 1.0
Several years back, initiatives were started to improve the notation
There were several goals:
Standardize the newer elements that have become popular
Decrease complexity for mapping from diagram elements to code
Standardize XML code that backs up the elements
These new standardized symbols will be showing up in tools soon

20. New Elements Activities can now have hierarchy
Activities can now have multiple instances
Events types now have descriptive elements
Gateway types now have descriptive elements
Connector types now have descriptive elements
A Connector type has been added that includes an integral gateway

21. Activity Hierarchy
In the past we would create separate diagrams for each major process and reference processes to each other
Following flow was not always easy
A new element has been introduced to allow workflows to have hierarchy
Levels are infinite
Double clicking on the “+” will open the lower level workflow

22. Multiple Instances New Activity Element to indicate multiple instances
New Activity Element to indicate looping

23. Event Types
The circumference of the event element can now describe “when”

24. Event Types The center of the event element can now describe “what”
Adding a label is no longer needed
Notice use of the circumference to indicate start, intermediate, and end

25. Event Types
The new “Intermediate” Event is used to depict a “break” that is outside of the process control

26. Gateway Types
The interior of the Gateway element can now describe “what”
Adding an explanation note is no longer needed

27. Connector Types
The line of the Connector element can now describe “what”
Adding an explanation note is no longer needed
Flow can be Conditional without using a Gateway Element
Normal Flow
Uncontrolled Flow
Conditional Flow
Default Flow
Message Flow
Association

28. Connector Types
New Conditional Flow Element saves space

29. Connector Types Exception flows can be depicted
Compensation flows can be depicted

30. Example
Simple Flow with a Hierarchy

31. Mapping to Code BPMN Elements can be mapped into an applications code
Properties with each element can be edited to map into the database
Mapping implements to workflow into the application
Workflow can now control and automate the application

32. Summary
BPMN 1.0 adds more powerful elements for use in workflow diagrams
Elements are standardized
And easier to use
Elements can be mapped into an applications code
