What is BPMN ? Business Process Modeling Notation Developed by Business Process Management Initiative (BPMI),and is currently maintained by the Object Management Groupsince the two organizations merged in 2005 Supports business process management for technical andbusiness users Bridge communication gap between business process design andimplementation
What? BPMN is simple Process diagrams business people like Less complex (business likes that too) Under the covers, technical enough for techies
What Does BPMN Not Do? State transitions Functional decomposition Organizational hierarchies Data modeling
What is BPMN Like? Similar to flowcharts and UML Activity diagrams Flow of activities with various messaging and data Can be used for service orchestration in SOA
Primary Components
Why BPMN? Standard notation Model concepts and/or implementation ofbusiness process Models high-level process concepts Notation is not complex
Issues With BPMN Limited complexity Process/conversation oriented Very high level Cannot see details of tasks or data
Solving BPMN Issues ViaUML BPMN as an extension to UML Enhanced ability to implement complexity Link implementation with orchestration Greater tool support Fill in gaps with details state, decomposition, data,implementationsBPMN for UML specification in progress at OMG
Executable VersesNon-executable Process flows can be executable or non executable Executable process follows specific rules Formal condition expressions are typically not includedin non-executable form Executable does not have Manual, Abstract, and othernon-execution elements
BPMN Diagram Zoo Process – Flow of activity, decisions, dataand events Collaboration – Conversations andinteractions (also process) Choreography – Tasks performed byparticipants and how participantscoordinate interactions via messages.

Understanding Collaborations
BPMN Choreography Sequence of interactions between Participants. Choreographies exist outside of or in between Pools. A Choreography Task is an atomic Activity in a ChoreographyProcess. The task represents an Interaction, which is one or two Messageexchanges between two Participants. Helps to show who initiates the activity and the first message.

Process Symbols
Activities Work that is performed within a Business Process. Activity can be atomic or non-atomic (compound) High-level, so does not describe the activity detail (notthe job of BPMN) Three types: Task, Sub-process, and Transaction
Activiy Symbols
Task Symbols (1 of 2)
Task Symbols (2 of 2)
What are Sub Processes? Is in the context of the process and can access thecontextual data. Can be expanded or collapsed to show detail of thesub-process or to hide the detail. Sub process MUST define an internal process with astart and end event. A sub process is only reusable within the parentprocess (i.e. it is not reusable in the overall design).
Sub Process Symbols
Gateways Gateways are used to control how SequenceFlows interact as they converge and divergewithin a Process. Capable of consuming or generating additionaltokens. Define decisions/branching (exclusive,inclusive, and complex), merging, forking, andjoining.
Gateway Symbols
About Data Symbols Data Objects provide information about whatActivities require and/or what they produce Represent a singular object or a collection ofobjects Data Input and Data Output provide the sameinformation for Processes
Data
Event Symbols Types
Start Events
Intermediate Events
End Events End Event indicates where a Process will end. In terms of Sequence Flows, the End Event ends the flow of theProcess, and thus, will not have any outgoing Sequence Flows. No Sequence Flow can connect from an End Event. Depending on the type, other rules are enforced (like errorhandling and/or how the process is terminated).
End Event Symbols
End Events (1 of 3)
End Events (2 of 3)

Pools A Pool is the graphical representation of a Participant ina Collaboration. It also acts as a “swimlane” and a graphical containerfor partitioning a set of Activities from other Pools Usually in the context of B2B situations Pool MAY have internal details, in the form of theProcess that will be executed Pool MAY have no internal details, i.e., it can be a"black box."
Lanes Lane (Swimlane) is a sub-partition within a Process Extend the entire length of the Process Lanes are used to organize and categorize Activities

CONDITIONAL FLOW
Default Sequence Flow
Exception Flow
Data Flow
Compensation Flow
Message Flows Flow of Messages between two Participants that are prepared tosend and receive them. A Message Flow MUST connect two separate Pools. They connect either to the Pool boundary or to Flow Objects withinthe Pool boundary. They MUST NOT connect two objects within the same Pool.
Message Flows
Message Flow Between Lanes
Data Associations Data Associations are used to move data between Data Objects,Properties, and inputs and outputs of Activities, Processes, andGlobalTasks. Tokens do not flow along a Data Association, and as a result theyhave no direct effect on the flow of the Process. Used for retrieving data from Data Objects or Process Data Inputsto fill the Activities inputs and push the output values from theexecution of the Activity back into Data Objects or Process DataOutputs.
