address the question “how well your solution works?”. If you have done
experiments to quantitatively evaluate your method, describe the experiment design (justify why you’ve
chosen to design your experiment in this way, not another way, and discuss what questions can be
answered by doing such an experiment). If you have developed a system, show some sample results of
your system. If you have opinions collected from users about your system, discuss what the users have
said and whether they indicate that your system is useful. Also discuss any deficiency of your system or
additional challenges that still have to be solved.
