Hello, Believe it or not I am still working on the old scea exam so the question is related to the old exam. What I wanted to know is how bad is it to digress from the provided BODM (Business Object Domain model)? More specifically I wanted to modify the meaning of Itinerary. From the provided use case descriptions it seems like an Itinerary can be purchased which does not make sense to me. So I wanted to fix this problem by introducing some new objects. Obviously this will cause all my sequence diagrams to use slightly different language than the gives use case descriptions.
from my point of view it is very important that your assignments meets all the requirements. To me, the BDM (which I have interpreted as from a customers perspective) is a requirement and has to be met.
If You browse this forum You'll find that some Ranchers changed BDOM and passed the exam, but majority (f.e. me :]) stuck with it. There are plenty of forum topics covering this area of assignment. Good luck and hurry, because You're running out of time.
