Ambiguity - Use Cases

[Muhammad Asif]

At the end of Prepare Itinerary it is stated that after the customer has selected flights, seats and confirmed the itinerary, the pay for itinerary use case is executed. The Pay for itinerary use case however says, that other use cases send priced itinerary.

The million dollar question is when is the itinerary priced?

Also, please note that the Price Itinerary use case says that the prepare Itinerary use case sends the prepared itinerary as input. ?

Any body having same sort of confusion ?

Hi,

If you look at the basic flow of the Prepare Itinerary use case, the system prices the itinerary AFTER the customer selects seats and BEFORE the customer confirms the itinerary.

The Use Case diagram should give you a clue. Notice that the Price Itinerary is included in the Prepare Itinerary.

I hope that helps.

The last line of the Basic flow in 'Prepare Itenary Use Cases' says:

System sends the priced itinerary to Pay for Itinerary Use Case

I think the above statement should clarify your question.

Bear in mind that there is supposed to be some ambiguity. Part of the assignment is deciding how to handle that ambiguity and documenting the assumptions you've made on that basis.

In this case, though, the provided information's not quite so unclear, depending on your reading - just look at every bit of information they provide from as many angles as you can, document what you think is unclear, and make sure that you can reason through what you decide to do based on those assumptions and ambiguities.

Thanks a lot for the detailed response. I really like the way you explain things
