Use case for Deliver Order

Question

I have an assignment where i have to create use cases for the deliver order. So here's a summary, the delivery driver said he was given 3 shipping receipts from his company to pick up stocks at the warehouse. He usually arrives at the warehouse at 8am and gives the shipping receipt to the warehouse manager and wait for them to load the stocks in the truck. Once all stocks are in his truck, he then go the first store as stated in his time sheet/schedule. When he arrived there, he gives a shipping receipt for the store manager to sign and then gives a copy to him and he kept a copy as well. After that, he left the store and go onto the next. I did my use cases using visio and this is what i got. Please help me with this as i would gladly appreciate it! Please click on this to see my use case

Answer 1

Well, although this is more a review, rather than a real question, here are some observations:

• Some of your UCs are no UCs:
  • Look at time sheet is merely a step in the including UC, not a UC itself.
  • Similarly Goto Store and Leave Store. They are just actions in scenarios of other UCs, not UCs on their own.
• You don't <<include>> an actor. You might just use a simple association. I prefer to stereotype them with <<secondary>> or use directed and undirected associations to differentiate between primary and secondary actor relations. However, placing secondary actors just to the right of the boundary seems to be common practice.
• Generally you should ask "what is the added value" and create UCs from that, rather than placing single steps of scenarios like handing out receipts or going to a store. So it's Deliver goods, Create invoice and the like which are real UCs.

I did not read your description. Instead I'd recommend to look into Bittner/Spence on how to write good use cases. Cockburn is ok too, but I prefer B/S.
