Examples

Consider the following sample procurement Process from the Buyer perspective (see Figure 10.24).

Figure 10.24 – Procurement Process Example

The Process comprises of two User Tasks

•Approve Order: After the quotation handling, the order needs to be approved by some regional manager to continue with the order and shipment handling.

•Review Order: Once the order has been shipped to the Buyer, the order and shipment documents will be reviewed again by someone.

The details of the Resource and resource assignments are not shown in the BPMN above. See below XML sample of the “Buyer” Process for the Resource usage and resource assignments for potential owners.
