6- Adam Johnson

In our team's redesign of YouTube, I feel the mental model is fairly obvious.  After our initial concept and sketch was tested by a user, they brought to our attention a problem (can't slide between YouTube and iTunes audio player).  Therefore, we took our initial redesign, along with the new knowledge we obtained from the user's comments, and implemented another feature (added the swipe ability) we felt necessary.  This was her thoughts, or mentality when using her design and a feature that would make her "feel good and competent" as Hoekman suggests (we just happened to agree with it being correct as well).  This in it's totality is the mental model of our redesign.  I feel this mental model contrasts the programmer's model in that the user provided nothing besides an idea, or a thought.  We took that thought, agreed with it, and would then proceed to write up some pseudo-code to pass onto an actual programmer to code and make it "come to life".  The implementation model would entail things such as specific details (as in utilization of if/then statements versus while statements or which language to write the new feature in, etc.).
