The purpose of the assignment is how an architect designs a system with vague requirements, misleading use cases. Because of this reason SUN is asking for
assumptions doc, otherwise they would have asked just provide us class diagram, sequence/activity diagrams and Component diagram.
Keep in mind, you solution should just
meet the requirements. They look for the approach of the solution rather than the solution itself.
Good luck.
