Comprehensive BPMN Case Study: Water Delivery Process

Key Concepts of BPMN

1. 1. Pools and Lanes:
      • • Pools represent participants or organizations involved in the process. In the diagram, there are two pools: “Customer” and “True Aquila Water Company.”
      • • Lanes divide pools into subprocesses or roles within the organization. Here, the “True Aquila Water Company” pool is divided into lanes for “Customer Service Assistant,” “Logistics Manager,” and “Delivery Worker.”

1. 1. Events:
      • • Events are represented by circles and indicate something that happens during the process. They can be start events (green circle with a thin border), intermediate events, or end events (red circle with a thick border).
      • • In the diagram, the start event is “Place Order” (green circle), and the end event is “Deliver Water” (red circle).

1. 1. Activities:
      • • Activities are tasks or work performed within the process, represented by rectangles with rounded corners. Examples include “Verify Customer Identity,” “Create Customer Account,” and “Arrange Delivery.”

1. 1. Gateways:
      • • Gateways, shown as diamonds, control the flow of the process, typically representing decisions or branching points. The diamond in the diagram labeled “Customer Exist?” is a decision point.

1. 1. Sequence Flows:
      • • Arrows connect activities, events, and gateways, showing the order of execution. Solid arrows indicate the primary flow, while dashed arrows may represent message flows or optional paths.

1. 1. Message Flows:
      • • Dashed arrows represent the exchange of information or messages between pools or lanes. In the diagram, dashed arrows connect the “Customer” pool to the “Customer Service Assistant” lane, indicating communication (e.g., phone calls or emails).

1. 1. Artifacts:
      • • Artifacts provide additional information about the process, such as annotations or data objects. The diagram includes annotations like “Over 90% of requests are made by phone call, 10% by email” and data objects like “Purchase Order [Created],” “Purchase Order [To be Assigned],” and “Purchase Order [To be Delivered].”

Interpretation of the Water Delivery Process Diagram

The BPMN diagram models the process of a customer placing an order for water delivery with True Aquila Water Company. Below is a step-by-step interpretation of the process:

1. 1. Initiation by the Customer:
      • • The process begins with the customer initiating an order through the “Place Order” start event. The annotation indicates that over 90% of orders are placed via phone calls, with 10% via email, suggesting a preference for direct communication.

1. 1. Customer Verification by Customer Service Assistant:
      • • The order is received by the “Customer Service Assistant” lane within True Aquila Water Company.
      • • The assistant performs the “Verify Customer Identity” activity to confirm the customer’s details.
      • • A gateway (“Customer Exist?”) follows, representing a decision point:
          • • If the customer does not exist (No), a new “Create Customer Account” activity is triggered to register the customer.
          • • If the customer already exists (Yes), the process moves forward.

1. 1. Order Forwarding and Processing:
      • • After verifying or creating the customer account, the “Forward Order” activity is performed, scheduled for “On Next Wednesday,” indicating a planned delivery date.
      • • A “Purchase Order [Created]” data object is generated during this step, representing the documentation of the order.

1. 1. Logistics Management:
      • • The order is passed to the “Logistics Manager” lane, where the “Arrange Delivery” activity is executed. This involves coordinating the logistics for water delivery.
      • • The “Purchase Order [To be Assigned]” data object is updated to reflect the order’s status as it moves toward delivery.

1. 1. Delivery Execution:
      • • The order is then handled by the “Delivery Worker” lane, where the “Deliver Water” end event occurs, marking the completion of the process.
      • • The “Purchase Order [To be Delivered]” and “Purchase Order [Completed]” data objects track the order’s progression and final status.

Analysis and Key Insights

1. 1. Process Efficiency:
      • • The process is streamlined, with clear roles (Customer Service Assistant, Logistics Manager, Delivery Worker) and a logical sequence of activities.
      • • The decision gateway (“Customer Exist?”) ensures that new customers are properly onboarded, preventing delays or errors.

1. 1. Communication Channels:
      • • The annotation about order placement (90% phone, 10% email) highlights the company’s reliance on direct communication, which may influence customer satisfaction and response times.

1. 1. Scheduling and Timing:
      • • The “On Next Wednesday” annotation suggests a fixed delivery schedule, which could be a bottleneck if customers require more flexibility. This might warrant further analysis to optimize delivery timing.

1. 1. Data Management:
      • • The use of “Purchase Order” data objects at different stages (Created, To be Assigned, To be Delivered, Completed) ensures transparency and tracking throughout the process, supporting accountability and auditability.

1. 1. Potential Improvements:
      • • The fixed delivery date (Next Wednesday) could be made more flexible to accommodate urgent orders.
      • • Automating the “Verify Customer Identity” and “Create Customer Account” steps with a customer portal could reduce manual effort and errors.
      • • Real-time tracking of deliveries could enhance customer experience by providing updates on order status.
