Subject: Question on uc3 again...
Question follows uc3 ubl diagram Consider the flow back through “Add Detail”
activity. An Order Response message is sent. A Receive Response activity occurs
leading to an update order choice. Why do we have three choices at “update order”? I
think there should just be “Cancel Order” or “Change Order”
The “Accept Order” activity produces no message,
while the other two produce the changed order message or the cancel order
message. What is the Seller expected to do if the Buyer enters the
Accept Order state? (A time out will lead to a performance failure…) It would make more sense to me if we reached Order Accepted by
going back to the Seller and then Receiving his Order Response Simple (or by
agreement, response not required.) |
