PHASE 3: DELIVERY PROCESS When the driver arrives to pick up the flowers from the store, the store sends a Pickup Confirmation event; when the driver delivers the flowers, the person receiving them confirms by signing the driver’s mobile device, and this generates a Delivery Confirmation event. Both Pickup Confirmation and Delivery Confirmation events have associated timestamps, and this allows the system to generate alert events. A Pickup Alert is generated if a Pickup Confirmation wasn’t reported within 5 minutes of the committed pickup time.
