The iterative design process was useful, because it allowed us to make changes rapidly and then get feedback to double check that we had actually made an improvement with that change. If we were to do this again, we would probably investigate which technologies to use more carefully. For all of us this was our first time using cssCSS, javascript, or phpPHP, and while we got the work done, we had to spend more time learning the technology than we would have liked. However, now that we know the technology better, it would be useful to run more high fidelity tests, because we believe the feedback from testing phases that actually involved a computer (heuristic evaluation and final user testing) to be the most valuable and actionable. For example, even though our paper prototype had radio buttons on the filter tab, none of our test subjects commented on them, and this was likely due to the low fidelity of paper. Again, web Web prototyping is so quick, that we think it might have been more useful to test a wire-frame prototype a little earlier on.
