Use Case Diagram for the Amazon Locker Service

Let’s build the use case diagram of the Amazon Locker System and understand the relationship between its main actors and functions. First, we’ll define the different elements of our system, followed by the complete use case diagram.

System

Our system is the Amazon Locker system. It manages automated package deliveries and returns via secure locker locations.

Actors

Now, we’ll define the main actors of our Amazon Locker system.

Primary actors

• Customer: This is an Amazon customer who ordered a package delivered to the Amazon Locker. The customer is responsible for selecting and booking a locker location for their order delivery. This actor can enter the code at the locker to retrieve their product, request a return, and drop off the package at the locker.

• Delivery person: This actor can also enter the code and add the product to the locker so the “Customer” can pick it up. This actor can also pick up a returned package from the locker. The delivery person uses unique, one-time codes for each delivery or return.
