I definitely would have presented more fundamentally different designs, rather than modifications on a single theme. By the end of the iterative process, the end product was quite different(probably a good thing), but many of the changes occurred very late in the process. Also, in an attempt to save work, prototypes were done in swing, as to use them in the final design. It might have been more effective to do the products in an easier prototyping tool such as Flex in order to test more prototypes. In addition, we learned the value of testing and prototyping. Many issues that we hadn't thought we brought out by these processes and led to a much better design in the end.
