The document describes a delivery agent system. It discusses how the system works by managing orders from when a customer places an order until the items are delivered. Delivery managers are responsible for scheduling deliveries and assigning couriers. The system uses an evolutionary process model to allow for user feedback. The objectives are to deliver products, support couriers, and ensure a good customer experience. Delivery agents collect and deliver packages. The system provides benefits like easier order management but also risks like data security issues. It has future potential to improve delivery accuracy and support online shopping.
