Case Study: ITECH2002 System Modeling - Fulfillment by Amazon (FBA)

This case study examines the Fulfillment by Amazon (FBA) subsystem, focusing on the use cases of creating an item list and item registration on the Amazon website from a reseller's perspective. It details the process of a reseller creating a shipping plan, Amazon verifying the list, and the reseller registering items. The study includes extended use case descriptions for both scenarios, outlining success and failure conditions, triggering events, actors, and flow of events. Furthermore, it presents activity diagrams and sequence diagrams illustrating the processes, a prototype of the item list creation interface, and a test plan for product registration. The case study also references academic sources related to Amazon and its ecosystem.
