Well, you can assume anything you want with the assignment as the architect - just document it.
That being said... I'd recommend reading the requirements carefully a few times before you decide on one solution over another. As stated in the documentation Sun provides, you're not allowed to rewrite the FFMS - they just did that "six months prior" and aren't interested. But obviously, you're going to have to do something to allow for reward travel in some means other than the current system of checking it across two different systems.
Just some food for thought, and trying not to bias you one way or another.
