return in online shopping use case diagram

I'm conviced that C is the correct one, but I want to hear your thoughts on A and B. The question is to get the functional and non functional requirements: in the functional of the Customer I have 'request a refund' and the functional for the Admin is 'process refunds', I considered the Admin as the secondary actor since he/she responds to initiated use case from the Customer (primary).ġ- Can I consider the Admin as a primary actor since he/she has some use cases that he/she can initiate ?Ģ- Which of the following use case diagrams that describes the system are correct ? (I made 3 of them but I'm uncertain) This system should have a fast response time and should tolerate common types of faults. The requirements at the client side are no more than a web-browser and a reasonable amount of memory on a computing device. It should also conform to the company standard STD0945. The system should conform to all applicable local and international laws. The system has an administration backend that allows administrators to add new products, manage inventory and process customer’s refunds if they existed as well.

It shall provide to customers a set of shipment methods, which are ground via local shipment agencies, next business day via DHL.

It provides a secure form of credit card payment service. Customer can place an order and enter his shipping details, credit card information. This system allows customers to browse the store catalog, pick the items, and put them in an e-cart.

I have a problem statement that describes an online E-commerce system:Īn E-commerce software system is going to be developed.
