BPMN 2.0 Basics
Business Process Model and Notation (BPMN) is a unified graphical notation standard crucial for visualizing business processes in a structured manner. BPMN 2.0, being the most widely adopted version, enables better collaboration between business and technical users alike.
Purpose of BPMN:
- Standard Visual Language: It bridges communication gaps across various departments, ensuring all stakeholders understand the process flows.
- Facilitation of Automation: The modeling is geared towards automating processes efficiently.
- Clear Documentation: It documents processes for training, compliance, and improvement purposes.
Core BPMN 2.0 Elements:
- Flow Objects:
- Events: Represent occurrences that affect the flow (e.g., start, end events).
- Activities: Tasks or subprocesses that need execution.
- Gateways: Decision points that determine the branching of flows.
- Connecting Objects:
- Sequence Flows: Indicate the order of activities.
- Message Flows: Illustrate communication between different participants.
- Associations: Connect text annotations or artifacts to the main diagram.
- Swimlanes:
- Pools and Lanes: Used to depict different participants and subdivide roles/departments.
- Artifacts:
- Data Objects: Illustrate inputs or outputs of a process.
- Text Annotations: Provide additional commentary.
- Groups: Visual organization of components without altering the flow.
Example BPMN Flow:
- Simple Order Process: Starts with receiving an order, validating it, deciding if stock is available, then either packing and shipping the order or notifying the customer.
Through using BPMN, Business Analysts can distinguish between the AS-IS (current) and TO-BE (future) process models, which together highlight areas for improvement and efficiency, leveraging the BPMN visual structure to engender clearer communication and decision-making.
