Business Process Modeling Notation

1
Business Process Modeling Notation

• BPMN

2
BPMN

• New standard for business process modeling
• Consists of one diagram
• The Business Process Diagram (BPD)
• Developed by the Business Process Management
  Institue (BPMI www.bpmi.org)

3
BPEL

• Business Process Executable Language
• Business Process Execution Language (or BPEL),
  is a business process modeling language that is
  executable. (wikipedia.org)
• BPMN can be mapped directly to BPEL to allow for
  executing processes

4
BPMN

• Basic Objectives
• Provides a standard for process modeling
• Notation is easy to understand
• Simplifies complex processes
• Is executable when mapped to BPEL

5
BPMN

• Enhances current process modeling tools
• Can be used with Visio
• Enhances swimlane maps
• Provides more detail to and does a better job of
  describing events, tasks, sub-processes,
  sequences, and decisions

6
BPMN Elements (Simplified)

• Flow Objects
• Connecting Objects
• Swimlanes
• Artifacts

7
BPMN Elements (Simplified)

• Flow Objects
• Events Generally indicates a trigger or an end
• Eg.
• Activities Identifies some work to be performed
• Eg.
• Gateways Determines decisions, forking merging,
  etc.
• Eg.

8
BPMN Elements (Simplified)

• Connecting Objects
• Sequence Flow Depicts the order of activities
• Message Flow Depicts messages flowing between to
  entities in the process
• Association Flow Depicts an association of data
  or text to a flow object

9
BPMN Elements (Simplified)

• Swimlanes
• Same concept as used in our swimlane mapping
  exercises. They help define roles in the process

10
BPMN Elements (Simplified)

• Artifacts
• Allows modelers to introduce new items to the
  model such as Data, Groupings, and Annotations
• Eg.
• Data Object
• Groupings
• Annotations

11
BPMN Examples

• Normal flow

Gateway (Decision)
Default Sequence Flow
Timer Event (Intermediate)
Message Event (Start)
Task (Flow Object)
End Event
Data Object (Artifact)
