Key Elements of BPMN

BPMN diagrams consist of four main categories of elements:

BPMN Notation Cheat Sheet

1. Flow Objects:

   • Events: Represented by circles, events indicate occurrences that affect the flow of the process. They can be start, intermediate, or end events.
   • Activities: Shown as rounded-corner rectangles, activities represent tasks performed within the process. They can be tasks or sub-processes.
   • Gateways: Diamonds that control the flow of the process based on conditions or decisions. Types include exclusive, parallel, and inclusive gateways.

2. Connecting Objects:
   

   

   BPMN Message Flow

   • Sequence Flows: Solid arrows indicating the order of activities.
   • Message Flows: Dashed arrows representing communication between participants.
   • Associations: Dotted lines linking artifacts to flow objects.

3. Swimlanes:

   • Pools: Represent major participants in a process.
   • Lanes: Subdivisions within pools that further categorize roles or responsibilities.

BPMN Notation: Balancing Simplicity and Complexity

BPMN notation is designed to be both simple and flexible, allowing for the representation of complex processes without compromising the clarity and familiarity of the diagrams. Within the fundamental categories of elements, additional details and variations can be incorporated to meet the needs of more intricate scenarios.

The table below illustrates how events in BPMN can be depicted using basic elements combined with additional variations. This approach enables BPMN to handle complexity while maintaining the notation’s core look and feel, ensuring that diagrams remain accessible and understandable.

This balance between simplicity and complexity makes BPMN a versatile tool for modeling a wide range of business processes, from straightforward workflows to highly detailed and intricate operations.

BPMN Example – Order Processing

The diagram is a Business Process Model and Notation (BPMN) diagram that illustrates a process for handling customer orders, specifically for a water delivery service. Let’s break down the key BPMN concepts and elements depicted in the diagram:

Key BPMN Elements in the Diagram

1. Pools and Lanes:

   • Pools: Represent major participants in the process. In this diagram, there are two pools: “Customer” and “The Tiny Aqua Bottled Water Company.”
   • Lanes: Subdivisions within pools that categorize activities by role or responsibility. The company pool is divided into “Customer Service Assistant,” “Logistic Department Manager,” and “Worker.”

2. Events:

   • Start Event: Represented by a green circle labeled “Place Order.” This event triggers the start of the process when a customer places an order.
   • Intermediate Event: The clock symbol indicates a timer event labeled “On Next Wednesday,” which signifies a delay or scheduled action.
   • End Event: Represented by a red circle labeled “Deliver Water,” marking the conclusion of the process when water is delivered.

3. Activities (Tasks):

   • Tasks: Represented by rounded-corner rectangles, these are the actions performed within the process. Examples include “Verify Customer Identity,” “Create Customer Account,” “Forward Order,” “Arrange Delivery,” and “Deliver Water.”

4. Gateways:

   • Exclusive Gateway: Represented by a diamond shape labeled “Customer Exist?”, this gateway controls the flow based on whether the customer already exists in the system. Depending on the condition, the process branches into either creating a new customer account or forwarding the order.

5. Artifacts:

   • Data Objects: Represented by folded-corner rectangles, these indicate documents or data involved in the process. Examples include “Purchase Order [To be Assigned],” “Purchase Order [To be Delivered],” and “Purchase Order [Completed].”
   • Annotations: The text box provides additional information, noting that over 90% of requests are made by phone call, with 10% by email.

6. Sequence Flow:

   • Solid arrows indicate the order of activities. The flow starts with placing an order, moves through verifying customer identity, and branches based on whether the customer exists. It continues through creating accounts or forwarding orders, arranging delivery, and concludes with delivering water.

Process Flow Interpretation

1. Order Placement:

   • The process begins when a customer places an order, indicated by the start event.

2. Customer Verification:

   • The customer service assistant verifies the customer’s identity.
   • If the customer exists, the order is forwarded. If not, a new customer account is created.

3. Order Processing:

   • Orders are scheduled to be forwarded on the next Wednesday, as indicated by the intermediate timer event.
   • The logistic department manager arranges the delivery of the water.

4. Delivery:

   • The worker delivers the water, marking the end of the process.
