BPMN 2.0 Descriptive Constructs
1 like3,125 views
The document provides an overview of descriptive constructs in BPMN 2.0 including activities, connecting objects, events, gateways, pools, lanes, artifacts, and data objects. It presents examples of processes for course enrollment and book borrowing. Key recommendations are that a process model should have a start and end event and all branches should be closed. The document is intended as lecture notes for a class on BPMN 2.0 descriptive constructs.

- 6. 6Jarrar © 2015 BPMN 2.0 Modeling Constructs BPMN 2.0 has a set of modeling elements such as: Activities Connecting objects Start events End events Artifacts Gateways Swimlanes (pool/lane, …) Data objects Throwing intermediate events Catching intermediate events
- 7. 7Jarrar © 2015 BPMN Descriptive Elements The selected BPMN 2.0 descriptive elements in this course are contained in this lecture slides. Descriptive elements are the basic BPMN symbols that can be used to model a business process.
- 8. 8Jarrar © 2015 Activities The task is a unit of work – the job to be performed. Task can be performed by human, system or even it can be an entire process.
- 9. 9Jarrar © 2015 Connecting Constructs Sequence Flow define the execution order of activities. Message Flow symbolizes information flow across organizational boundaries. Basic rules: attached to pools, activities or message events. The order of message exchanges can be specified by combining the message flow and sequence flow.
- 10. 10Jarrar © 2015 Start Events Un-typed start event typically marks the standard start of a process. Start Message Event, a process instance is started on receive of a message. Start Timer Event, a process instance is started on cyclic timer events, points in time, after time spans or time outs.
- 11. 11Jarrar © 2015 End Events The un-typed end event typically marks the standard end of a process. End Message Event, at the end of the process, a message is sent. Terminate End Event, triggering the immediate termination of a process instance. All steps in execution of parallel branches are terminated.

- 13. 13Jarrar © 2015 Example: Book Borrowing Validation
- 14. 14Jarrar © 2015 Example: Start Timer Event
- 15. 15Jarrar © 2015 Some Rules of Thumb There are a set of tips and rules to have a valid process models, below are two of them: Process model should have start and end event. All process branches should be closed. More rules to be provided as progressing with the course.
- 16. 16Jarrar © 2015 Artifacts Any text can be associated with a text annotation to provide additional documentation. Group Any arbitrary set of objects can be defined as group to show that they are logically together.
- 17. 17Jarrar © 2015 Gateways Data-based exclusive (XOR) gateway When splitting, it routes the sequence flow to exactly one of the outgoing branches based on conditions. When merging, it waits one incoming branch to complete before triggering the outgoing flow .
- 18. 18Jarrar © 2015 Gateways Parallel Gateway When splitting, the sequence flow, all outgoing branches are activated simultaneously. When merging, parallel branches it waits for all incoming branches to complete before triggering the outgoing flow.
- 19. 19Jarrar © 2015 Pool Pools represent responsibilities for activities in a process. Pool represent whole organization units.
- 20. 20Jarrar © 2015 Lanes Lanes same as pools represent responsibilities for activities in a process. However, lanes subdivide pools or other lanes hierarchically.
- 21. 21Jarrar © 2015 Collapsed Pool Collapsed pools hide all internals of the contained processes.
- 22. 22Jarrar © 2015 Data Objects Data object represents information flowing through the process, such as business documents, emails or letters. Data store, a place where the process can read or write data, e.g. a database or a filling cabinet. It persists beyond the lifetime of the process instance.
