My teacher just gave me a task to create a use case diagram based on her given use cases and I have 2 actors which is Admin and Inventory officer and they are most likely the same to each other, but I'm not sure enough if I'm doing it right.
This is the use cases my teacher gave to me:
Administrator(Actor) Add User Account Update User Account Deactivate User Account View User Account Add User Group Update User Group Remove User Group View User Group Add Vendor Update Vendor Deactivate Vendor View Vendor Add Location Update Location Deactivate Location View Location Add Product Category Update Product Category Remove Product Category View Product Category Add Product Update Product Deactivate Product View Product Add Status Update Status View Status Create Purchase Requisitions Modify Purchase Requistions Submit Purchase Requisitions View Purchase Requistions Cancel Purchase Order Send Purchase to Supplier View Purchase Orders View Purchase Requisitions Cancel Purchase RequisitionsWithdraw Items Receive Items View Inventory View Notifications Exipiration Alerts View Product Updates View Product Updates View Supplier Updates View Location Updates View Cancelled Purchase Requisitions View Approved Purchase Requisitions View Purchase Orders View Withdrawn items View Received Items View Aging of Purchase Requisitions Report View Purchase Requisitions by Status Report View Aging of Purchase Orders View Purchase Order Status View Inventory Report View Vendor List report View Location List report View Product List report My question is do I need to improve my work? Or it's all good to go?
